Environment Setup Scripts - -**Script 1: Environment Check (`scripts/check-env.sh`)** -- Verifies Docker Engine version -- Verifies Docker Compose V2 availability -- Checks for required network utilities -- Reports available system resources -- Exits with clear error messages if requirements not met - -**Script 2: Environment Reset (`scripts/reset-env.sh`)** -- Stops all running Docker containers -- Removes all Docker networks -- Removes all Docker volumes (with confirmation) -- Provides clean slate for next lab - -**Script 3: Docker Compose Validation (`scripts/validate-compose.sh`)** -- Runs `docker compose config` on specified compose file -- Validates YAML syntax -- Reports configuration errors before deployment - -### 5. README Structure - -**Required sections:** -1. Project overview (what and why) -2. Prerequisites (Docker, utilities) -3. Quick start (clone, check environment) -4. Lab overview (5 labs briefly described) -5. Git workflow brief -6. Troubleshooting pointers - -**Tone:** Direct, simple, technically accurate (per PRD requirements) - ---- - -## Validation Architecture - -### Testing Approach for Phase 1 - -Since this phase sets up infrastructure and tooling, validation focuses on: - -1. **Script Validation:** Each script must: - - Execute without errors on a properly configured system - - Provide clear error messages when requirements aren't met - - Be idempotent where applicable (reset-env.sh) - - Exit with appropriate status codes - -2. **Structure Validation:** - - All required directories exist - - README.md is accessible and complete - - Scripts are executable (`chmod +x`) - -3. **Documentation Validation:** - - README accurately describes setup process - - Setup instructions can be followed by a new student - - Prerequisites are clearly stated - -### "Done" Criteria - -**Success Criterion 1:** Studente può clonare la repository e trovare istruzioni chiare per configurare Docker Engine >= 24.0 e Compose V2 -- **Validation:** README contains clear Docker installation/verification instructions -- **Test:** New user can clone repo and follow instructions successfully - -**Success Criterion 2:** Studente può eseguire script di verifica ambiente che controlla Docker, utility di rete, e risorse minime -- **Validation:** `scripts/check-env.sh` exists and runs successfully -- **Test:** Script reports all required components correctly - -**Success Criterion 3:** Studente può eseguire comando di reset completo ambiente (cleanup volumi, reti) -- **Validation:** `scripts/reset-env.sh` exists and cleans all Docker artifacts -- **Test:** After running, `docker ps` shows no containers, `docker network ls` shows only default networks - -**Success Criterion 4:** Ogni file docker-compose.yml può essere validato con `docker compose config` prima dell'uso -- **Validation:** `scripts/validate-compose.sh` exists and validates compose files -- **Test:** Script catches YAML errors and configuration issues - -**Success Criterion 5:** Repository ha struttura chiara con cartelle `labs/`, `how-to-guides/`, `reference/` -- **Validation:** All directories exist with appropriate placeholder files -- **Test:** Directory structure matches planned layout - ---- - -## Specific Ideas - -### Script Headers (for consistency) - -All scripts should include: -```bash -#!/bin/bash -# Laboratori Cloud - [Script Purpose] -# Part of: "Corso Soluzioni Cloud" -# -# Description: [What this script does] -# Usage: [command] [options] -``` - -### README Template - -```markdown -# Laboratori Cloud - Corso Soluzioni Cloud - -Simulazione pratica di servizi cloud usando Docker locale. - -## Prerequisiti - -- Docker Engine >= 24.0 -- Docker Compose V2 -- Utility: netcat, curl, iproute2 - -## Quick Start - -1.

All setup elements are required before labs can begin. - ---- - -## Implementation Notes - -### Safety First Considerations - -- `reset-env.sh` should require confirmation before destructive operations -- Scripts should not run as root unless absolutely necessary -- Validation scripts should check for potential conflicts (port conflicts, existing containers) - -### Little Often Approach - -- Create one script at a time -- Validate each script before moving to next -- Commit after each working script - -### Double Check Verification - -- After setup, run `check-env.sh` to verify everything works -- Test `reset-env.sh` on a clean system to ensure it doesn't break anything -- Validate README instructions by following them literally -

-```markdown -# Explanation: Parallelismi tra Docker Permissions e AWS IAM - -In questo documento esploreremo come i permessi Docker e la gestione utenti Linux simulano i concetti di Identity and Access Management (IAM) nei cloud provider come AWS. Comprendere questi parallelismi ti aiuterà a trasferire le conoscenze acquisite localmente agli ambienti cloud reali. - -## Cos'è IAM? - -**IAM (Identity and Access Management)** è il framework che controlla: -- **Identity:** Chi sei (autenticazione) -- **Access:** Cosa puoi fare (autorizzazione) - -AWS IAM, Azure IAM, Google Cloud IAM sono tutti basati sullo stesso concetto fondamentale: le identità hanno permessi specifici su risorse specifiche. - ---- - -## Il Parallelismo Fondamentale - -### Utente Linux = IAM User - -| Locale | Cloud | -|--------|-------| -| Un utente Linux (`lab01_student`) | Un IAM User (`alice`) | -| Può fare login al sistema | Può fare login ad AWS | -| Ha UID univoco | Ha User ID univoco (AIDAI...) | -| Appartiene a gruppi | Appartiene a IAM Groups | - -**Similitudine:** Entrambi rappresentano un'identità umana o di servizio che può autenticarsi. - -**Differenza:** Gli utenti Linux sono locali a una singola macchina, gli IAM Users sono globali all'account AWS. - -### Gruppo Linux = IAM Group - -| Locale | Cloud | -|--------|-------| -| Gruppo `docker` | IAM Group `Developers` | -| Membri ereditano permessi del gruppo | Membri ereditano policies del gruppo | -| Utente può essere in multipli gruppi | Utente può essere in multipli gruppi | -| `groups user` mostra membrianze | `aws iam list-groups-for-user` | - -**Similitudine:** I gruppi rendono facile gestire i permessi per molti utenti. Aggiungi un utente al gruppo e ha automaticamente tutti i permessi del gruppo. - -**Differenza:** I gruppi Linux sono definiti localmente, i gruppi IAM sono definiti centralmente e possono avere utenti跨-region. - -### Socket Docker = Service Endpoint - -| Locale | Cloud | -|--------|-------| -| `/var/run/docker.sock` | AWS API endpoint (`https://ec2.amazonaws.com`) | -| Accessibile solo con permessi corretti | Accessibile solo con credenziali valide | -| `chmod 660` limita l'accesso | IAM policies limitano l'accesso | - -**Similitudine:** Entrambe sono risorse protette che richiedono autorizzazione per essere utilizzate. - -**Differenza:** Il socket Docker è un file Unix locale, gli API endpoint sono servizi web remoti. - -### Permessi File = IAM Policy - -| Locale | Cloud | -|--------|-------| -| `rw-rw----` su socket | JSON policy con `Effect: Allow/Deny` | -| Utente deve essere nel gruppo `docker` | Utente deve avere policy permessiva | -| `chmod` cambia permessi | `AttachUserPolicy` assegna policy | - -**Similitudine:** Entrambi definiscono regole esplicite su chi puo fare cosa. - -**Differenza:** I permessi Linux sono semplici (read/write/execute), le IAM policies sono espressioni complesse con condizioni, wildcard, e resource-level permissions. - ---- - -## Esempio Pratico: Setup di un Nuovo Sviluppatore - -### Scenario Locale - -```bash -# 1. Crea utente per il nuovo sviluppatore -sudo useradd -m -s /bin/bash mario_rossi - -# 2. Aggiungi al gruppo docker (permette di lanciare container) -sudo usermod -aG docker mario_rossi - -# 3. Verifica -groups mario_rossi -# Output: mario_rossi : mario_rossi docker - -# 4. Mario ora puo lanciare container -sudo -u mario_rossi docker run alpine whoami -``` - -### Scenario Cloud AWS (Equivalente) - -```bash -# 1. Crea IAM User per il nuovo sviluppatore -aws iam create-user --user-name mario_rossi - -# 2. Crea gruppo per sviluppatori (se non esiste) -aws iam create-group --group-name Developers - -# 3. Allega policy al gruppo (permette di usare EC2/containers) -aws iam attach-group-policy \ - --group-name Developers \ - --policy-arn arn:aws:iam::aws:policy/PowerUserAccess - -# 4.

Mario ora puo lanciare istanze EC2 (equivalente a container) -aws ec2 run-instances --image-id ami-12345 ... -``` - -**Parallelismo:** -- Entrambi iniziano creando un'identità -- Entrambi usano gruppi per gestire i permessi -- Entrambi verificano l'appartenenza al gruppo -- Entrambi ora possono lanciare risorse (container/EC2) - ---- - -## Il Principio del Minimo Privilegio - -### Locale: Non-Root Containers - -**Perché non root?** -- Root in container = root sull'host (se vulnerabilità kernel) -- Root puo leggere/scrivere qualsiasi file -- Root puo modificare configurazioni di sistema - -**Soluzione locale:** -```dockerfile -# Dockerfile con utente non-root -FROM alpine:3.19 -RUN adduser -D -u 1000 appuser -USER appuser -CMD ["sh", "-c", "whoami"] -``` - -**Verifica:** -```bash -docker exec container whoami -# Output: appuser (NON root) -``` - -### Cloud: IAM Policies Restrittive - -**Perché policy minime?** -- Chiave compromessa = danno limitato -- Principio di least privilege -- Audit e compliance requirements - -**Soluzione cloud:** -```json -{ - "Version": "2012-10-17", - "Statement": [ - { - "Effect": "Allow", - "Action": [ - "s3:GetObject", - "s3:PutObject" - ], - "Resource": "arn:aws:s3:::my-bucket/*" - } - ] -} -``` - -**Verifica:** -```bash -# Simula accesso dell'utente -aws iam simulate-principal-policy \ - --policy-source-arn arn:aws:iam::123456789012:user/mario_rossi \ - --action-names s3:DeleteBucket \ - # Output: Decision: Deny (policy non permette DeleteBucket) -``` - -**Parallelismo:** -- Entrambi limitano cosa l'identità puo fare -- Entrambi riducono la superficie di attacco -- Entrambi sono verificabili tramite test - ---- - -## Differenze tra Locale e Cloud - -### 1. Scope dei Permessi - -| Locale | Cloud | -|--------|-------| -| Permessi validi solo su questa macchina | Permessi validi per tutto l'account AWS | -| Utente locale accede solo a risorse locali | IAM user accede a risorse globali | -| Gruppi definiti in `/etc/group` | Gruppi definiti in IAM (centralizzato) | - -**Implicazione:** Nel cloud, un utente con permessi S3 puo accedere a tutti i bucket S3 nell'account, non solo a quelli "vicini" come nel filesystem locale. - -### 2. Complessità delle Policy - -| Locale | Cloud | -|--------|-------| -| Semplice: lettura/scrittura/esecuzione | Complesso: conditions, IP restrictions, MFA | -| Basato su owner/group/other | Basato su JSON con wildcards | -| Binario: o hai permesso o no | Granulare: resource-level, tag-based, time-based | - -**Esempio Cloud (non possibile localmente):** -```json -{ - "Effect": "Allow", - "Action": "s3:*", - "Resource": "*", - "Condition": { - "IpAddress": { - "aws:SourceIp": ["203.0.113.0/24"] - }, - "DateGreaterThan": { - "aws:CurrentTime": "2024-01-01T00:00:00Z" - }, - "Bool": { - "aws:MultiFactorAuthPresent": "true" - } - } -} -``` - -**Implicazione:** Le IAM policies sono piu potenti ma anche piu complesse da capire e debuggare. - -### 3. Audit e Logging - -| Locale | Cloud | -|--------|-------| -| `/var/log/auth.log` per login sudo | CloudTrail per tutte le chiamate API | -| `last` mostra ultimi login | IAM Access Analyzer mostra attivita | -| Manuale correlare eventi | Ricerche automatiche su CloudTrail Logs | - -**Implicazione:** Nel cloud hai audit trail automatico, completo e ricercabile. Localmente devi configurare e mantenere i log. - -### 4. Autenticazione - -| Locale | Cloud | -|--------|-------| -| Password, SSH key | Access Key ID, Secret Access Key, Session Token | -| Password scade mai (default) | Access keys devono essere ruotate regolarmente | -| MFA non disponibile | MFA obbligatorio per root/users in molte organizzazioni | - -**Implicazione:** Nel cloud, l'autenticazione e piu sicura di default (rotazione automatica, MFA, sessioni temporanee). - ---- - -## Comandi Equivalenti: Quick Reference - -| Operazione | Locale | Cloud AWS | -|------------|--------|-----------| -| **Crea utente** | `sudo useradd -m user` | `aws iam create-user --user-name user` | -| **Aggiungi a gruppo** | `sudo usermod -aG docker user` | `aws iam add-user-to-group --group-name Developers --user-name user` | -| **Verifica permessi** | `groups user` | `aws iam list-attached-user-policies --user-name user` | -| **Test accesso** | `sudo -u user docker ps` | `aws sts get-caller-identity` | -| **Eleva privilegi** | `sudo command` | `aws sts assume-role` | -| **Revoca permessi** | `sudo gpasswd -d user docker` | `aws iam detach-user-policy --user-name user --policy-arn ...` | -| **Elimina utente** | `sudo userdel user` | `aws iam delete-user --user-name user` | - ---- - -## Best Practices Transferibili - -### 1. Mai Usare Root per Lavoro Normale - -**Locale:** -```bash -# SBAGLIATO: Log in come root -ssh root@server - -# GIUSTO: Log in come utente normale, usa sudo quando serve -ssh user@server -sudo command -``` - -**Cloud:** -```bash -# SBAGLIATO: Usa root account AWS (l'email con cui ti sei registrato) -# Mai usare root account per operazioni quotidiane - -# GIUSTO: Crea IAM User con permessi limitati -aws iam create-user --user-name daily-ops-user -aws iam attach-user-policy --user-name daily-ops-user --policy-arn ... -``` - -### 2. Usa Gruppi per Gestire Permessi - -**Locale:** -```bash -# Invece di dare permessi a ogni singolo utente -sudo usermod -aG docker user1 -sudo usermod -aG docker user2 -sudo usermod -aG docker user3 - -# Tutti automaticamente ereditano i permessi del gruppo docker -``` - -**Cloud:** -```bash -# Invece di attachare policy a ogni singolo utente -aws iam create-group --group-name Developers -aws iam attach-group-policy --group-name Developers --policy-arn ... -aws iam add-user-to-group --group-name Developers --user-name user1 -aws iam add-user-to-group --group-name Developers --user-name user2 - -# Tutti automaticamente ereditano le policies del gruppo Developers -``` - -### 3. Verifica i Permessi - -**Locale:** -```bash -# Verifica che l'utente abbia i permessi corretti -groups user -id user -sudo -u user docker ps -``` - -**Cloud:** -```bash -# Verifica che l'utente abbia le policies corrette -aws iam list-attached-user-policies --user-name user -aws iam simulate-principal-policy --policy-source-arn ... --action-names s3:GetObject -``` - ---- - -## Conclusione - -I concetti che hai imparato in questo lab - utenti, gruppi, permessi - si applicano direttamente ad AWS IAM e altri cloud provider. La differenza principale e la scala e la complessita: nel cloud, questi concetti sono potenziati con condizioni granulari, audit automatico, e credenziali ruotabili. - -Quando lavorerai con AWS IAM, ricorda: -- IAM User = Utente Linux (identità) -- IAM Group = Gruppo Linux (raccolta di utenti con stessi permessi) -- IAM Policy = Permessi file/socket (regole di accesso) -- Service Endpoint = Socket Docker (risorsa protetta) - -Comprendendo questi parallelismi, sarai in grado di applicare le conoscenze locali al cloud con fiducia. - ---- - -## Approfondimenti - -- [AWS IAM Documentation](https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction.html) -- [IAM Best Practices](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) -- [Tutorial: Permessi Docker](../tutorial/02-docker-group-permissions.md) -- [Reference: Tabella Parallelismi](../reference/iam-parallels.md) -``` - -Key points: -- Clear explanation of IAM concepts -- Side-by-side comparisons -- Practical examples -- Best practices transferable to cloud -- Links to AWS documentation -- Covers PARA-01 (Docker mapped to IAM), PARA-03 (differences documented), PARA-04 (commands shown) - - - test -f labs/lab-01-iam/explanation/docker-iam-parallels.md && grep -q "IAM\|AWS\|differenza\|difference" labs/lab-01-iam/explanation/docker-iam-parallels.md && wc -l labs/lab-01-iam/explanation/docker-iam-parallels.md | awk '{if($1>=80) print "PASS"; else print "FAIL: Explanation too short ("$1" lines, expected 80+)"}' - - Explanation document created with IAM parallels and local-cloud differences - - - - - -1.

Building custom authentication layers teaches wrong lessons about using established security patterns. - -## Common Pitfalls - -### Pitfall 1: Group Membership Requires Re-Login -**What goes wrong:** User added to docker group but `docker ps` still fails with "permission denied" -**Why it happens:** Group membership is evaluated at login; current session doesn't see new groups -**How to avoid:** Teach students to use `newgrp docker` OR `su - user` OR logout/login -**Warning signs:** "Got permission denied while trying to connect to the Docker daemon socket" - -### Pitfall 2: Testing as Wrong User -**What goes wrong:** Test passes when run as root but fails as regular user -**Why it happens:** Root can bypass Docker socket permissions -**How to avoid:** All tests MUST run as non-privileged user, use `sudo -u student1` for testing -**Warning signs:** Test passes with `sudo` but fails without it - -### Pitfall 3: Insufficient Verification of Non-Root Execution -**What goes wrong:** Container configured with `USER` directive but still running as root -**Why it happens:** Dockerfile USER directive not applied, or docker compose `user` override missing, or container switches back to root -**How to avoid:** Always verify with `docker exec whoami` AND `docker inspect | grep User` -**Warning signs:** Container process shows as root in `docker top` or `docker inspect` - -### Pitfall 4: Socket Permissions After Docker Restart -**What goes wrong:** Docker daemon restart changes socket permissions -**Why it happens:** Docker daemon may reset socket ownership on restart -**How to avoid:** Document that docker group membership persists but socket may need verification -**Warning signs:** Previously working docker commands fail after `sudo systemctl restart docker` - -## Code Examples - -Verified patterns from official sources: - -### Creating Non-Root Dockerfile -```dockerfile -# Source: Docker security best practices -FROM alpine:3.19 - -# Create non-root user with specific UID/GID for consistency -RUN addgroup -g 1000 appgroup && \ - adduser -D -u 1000 -G appgroup appuser - -# Switch to non-root user BEFORE any operations that don't require root -USER appuser - -# Verify non-root execution -CMD ["sh", "-c", "echo 'Running as:' && whoami"] -``` - -### Verifying Container User Runtime -```bash -# Source: Docker CLI documentation -# Method 1: Execute whoami inside container -docker exec whoami -# Expected output: appuser (NOT root) - -# Method 2: Inspect container configuration -docker inspect --format='{{.State.User}}' -# Note: May show empty if using docker compose user directive - -# Method 3: Check process on host -docker top -# Look at USER column - should show UID (e.g., 1000), NOT 0 (root) - -# Method 4: Comprehensive check script -#!/bin/bash -container_name=$1 -actual_user=$(docker exec $container_name whoami) -echo "Container running as: $actual_user" -if [ "$actual_user" = "root" ]; then -

-## State of the Art - -| Old Approach | Current Approach | When Changed | Impact | -|--------------|------------------|--------------|--------| -| Rootful Docker only | Rootless Docker available | Docker 19.03+ | Labs can now demonstrate true non-root Docker daemon | -| `--user` flag only | User namespaces + userns-remap | Docker 1.10+ | Multiple isolation layers for defense-in-depth | -| Manual test scripts | BATS framework adoption | 2020+ | Professional-grade test infrastructure for bash | - -**Deprecated/outdated:** -- **Docker socket as `chmod 777`:** NEVER use, completely bypasses security -- **Running daemons as root inside container:** Violates security best practices -- **Using `--privileged` flag:** Defeats container isolation, only for edge cases in advanced labs -

-**Success Criteria 2:** Studente comprende il parallelismo tra utenti Linux/permessi Docker e IAM Users/Roles in cloud -- **How to verify:** Explanation document includes mapping table comparing Linux concepts to AWS IAM -- **Manual check:** Review `explanation/docker-iam-parallels.md` for explicit parallels -- **Test command:** None — conceptual understanding verified through documentation quality - -**Success Criteria 3:** Nessun container gira come root (principio minimo privilegio verificato) -- **How to verify:** Automated test checks `docker exec whoami` returns non-root -- **Test command:** `bash tests/02-non-root-test.sh` -- **Manual check:** `docker inspect` shows User field set, docker-compose.yml has `user:` directive - -**Success Criteria 4:** Lab include Tutorial, How-to Guides, Reference, Explanation (Diátaxis completo) -- **How to verify:** File structure check confirms all 4 document types exist -- **Manual check:** Review each document for Diátaxis compliance -- **Test command:** `find labs/lab-01-iam -name "*.md" | grep -E "(tutorial|how-to|reference|explanation)"` -

-### TDI Methodology Verification - -**RED Phase (Pre-Implementation):** -- Test scripts are written BEFORE docker-compose.yml or Dockerfiles -- Tests explicitly fail when run against non-existent infrastructure -- Example: `test_01-user-creation-test.sh` checks for users that don't exist yet - -**GREEN Phase (Implementation):** -- Minimum infrastructure created to make tests pass -- docker-compose.yml includes `user:` directive for all services -- Test execution produces all PASS results - -**REFACTOR Phase (Optimization):** -- Test coverage remains 100% after optimizations -- Documentation improvements don't break existing tests -- Security enhancements (e.g., user namespaces) are tested before deployment - -### INF-01 Verification (No Root Containers) - -**Automated Verification:** -```bash -# Test runs for every container defined in docker-compose.yml -for service in $(docker compose ps --services); do - container_name=$(docker compose ps -q $service) - actual_user=$(docker exec $container_name whoami 2>/dev/null) - if [ "$actual_user" = "root" ]; then - echo "FAIL: $service running as root" - exit 1 - fi -done -echo "PASS: All containers running as non-root" -``` - -**Manual Verification:** -1. Check docker-compose.yml for `user:` directive on all services -2. Run `docker compose ps` to get container names -3. Run `docker top ` and verify USER column != root -4. Run `docker inspect ` and verify Config.User is set - -**Continuous Verification:** -- Quick test runs on every commit during development -- Full test suite runs before merging lab branch to main -- Phase gate requires 100% PASS rate for all tests - -## Open Questions - -1. **Should we teach rootless Docker in Lab 1?** - - What we know: Rootless Docker is more secure but adds complexity (uidmap, slirp4netns, etc.) - - What's unclear: Is it too advanced for first lab? - - Recommendation: Teach standard docker group model in Lab 1, mention rootless as "advanced topic" in Explanation - -2. **How to handle the "newgrp" limitation in automated tests?** - - What we know: Group membership requires re-login to take effect - - What's unclear: Best practice for automated testing without interactive login - - Recommendation: Test group membership with `groups` command, not actual Docker access, or use `sg docker -c "docker ps"` - -3. **What UID/GID should we use for non-root containers?** - - What we know: Common practice is 1000:1000, but may conflict with host users - - What's unclear: Should we use specific UIDs to avoid conflicts? - - Recommendation: Use 1000:1000 for simplicity, document potential conflicts in troubleshooting guide - -## Sources - -### Primary (HIGH confidence) -- Docker Engine Security Documentation - https://docs.docker.com/engine/security/ -

Cross-Reference Link Integrity - -**Test:** Click all markdown links in documentation files to verify they resolve correctly -**Expected:** All relative links should point to existing files -**Why human:** Link validation requires filesystem context that grep cannot fully verify - -### 4. IAM Parallel Pedagogical Value - -**Test:** Review explanation/docker-iam-parallels.md for clarity and educational value -**Expected:** Parallels should be accurate and helpful for someone learning IAM concepts -**Why human:** Subjective assessment of educational quality requires human judgment - -### Gaps Summary - -No gaps found.

-### Pattern 1: VPC Simulation with Custom Bridge Networks -**What:** Create isolated networks that simulate VPC and subnets using explicit CIDR blocks -**When to use:** All multi-tier applications requiring network segmentation -**Example:** -```yaml -# Source: Docker Compose networking documentation -# https://docs.docker.com/compose/networking/ - -networks: - # Simulates VPC with public subnet - vpc-public: - driver: bridge - name: lab02-vpc-public - ipam: - config: - - subnet: 10.0.1.0/24 - gateway: 10.0.1.1 - - # Simulates VPC with private subnet - vpc-private: - driver: bridge - name: lab02-vpc-private - ipam: - config: - - subnet: 10.0.2.0/24 - gateway: 10.0.2.1 - internal: true # Blocks external internet access - -services: - # Web server in public subnet - web: - image: nginx:alpine - networks: - - vpc-public - ports: - - "127.0.0.1:8080:80" # INF-02: Only expose on localhost, NOT 0.0.0.0 - - # Database in private subnet - db: - image: postgres:16-alpine - networks: - - vpc-private - # No ports exposed - private network only -``` - -### Pattern 2: Network Isolation Verification -**What:** Test that containers on different networks cannot communicate -**When to use:** TDD RED phase, verification of INF-02 compliance -**Example:** -```bash -# Source: Docker bridge network documentation -# https://docs.docker.com/engine/network/drivers/bridge/ - -#!/bin/bash -# Test 1: Containers in same network can communicate -docker run -d --name container1 --network vpc-public alpine sleep 3600 -docker run -d --name container2 --network vpc-public alpine sleep 3600 - -docker exec container1 ping -c 2 container2 -# Expected: SUCCESS (containers in same network can communicate) - -# Test 2: Containers in different networks are isolated -docker run -d --name container3 --network vpc-private alpine sleep 3600 - -docker exec container1 ping -c 2 container3 -# Expected: FAILURE (different networks are isolated) - -# Test 3: Private network not accessible from host -docker exec container3 wget -O- http://container2 -# Expected: FAILURE (private network isolation) -``` - -### Pattern 3: VPC Nomenclature Mapping -**What:** Use cloud-style naming for local networks to teach parallelism -**When to use:** All network definitions in docker-compose.yml -**Example:** -```yaml -# Cloud-style naming for local networks -networks: - # Naming convention: -- - lab-vpc: # Simulates VPC - driver: bridge - ipam: - config: - - subnet: 10.0.0.0/16 # VPC CIDR block - - public-subnet-1a: # Subnet name includes AZ simulation - driver: bridge - ipam: - config: - - subnet: 10.0.1.0/24 # Public subnet CIDR - - private-subnet-1a: - driver: bridge - internal: true # No internet gateway (private subnet) - ipam: - config: - - subnet: 10.0.2.0/24 # Private subnet CIDR -``` - -### Anti-Patterns to Avoid -- **Using default bridge network:** No DNS resolution, poor isolation, not production-grade -- **Exposing private ports on 0.0.0.0:** Violates INF-02, allows external access to private services -- **Mixing public/private services in same network:** Breaks isolation model, defeats learning objective -- **Using `--link` flag:** Legacy feature, user-defined networks provide automatic DNS -- **Skipping network tests:** TDD approach requires RED→GREEN→REFACTOR for network setup - -## Don't Hand-Roll - -| Problem | Don't Build | Use Instead | Why | -|---------|-------------|-------------|-----| -| Network isolation | Custom iptables rules | Docker bridge networks | Built-in isolation, battle-tested, easier to debug | -| DNS resolution | Custom /etc/hosts management | Docker embedded DNS | Automatic service discovery, no manual updates | -| IP allocation | Custom IP assignment scripts | Docker IPAM | Prevents conflicts, handles subnet calculations | -| Network testing | Custom ping wrappers | Standard tools: ping, curl, nc | Students already know these tools, portable | - -**Key insight:** Docker's networking primitives are sufficient for VPC simulation. Building custom network layers teaches the wrong lesson about using platform-provided isolation. - -## Common Pitfalls - -### Pitfall 1: Default Bridge Network Limitations -**What goes wrong:** Students use default bridge, find containers can't resolve each other by name -**Why it happens:** Default bridge doesn't have embedded DNS; requires --link (legacy) or IP addresses -**How to avoid:** Always create custom networks with `docker network create` or `networks:` in Compose -**Warning signs:** Using IP addresses to connect containers, "name resolution failed" errors - -### Pitfall 2: Publishing Private Network Ports on 0.0.0.0 -**What goes wrong:** `ports: ["8080:80"]` publishes on all interfaces, violating INF-02 -**Why it happens:** Default port binding is 0.0.0.0 (all interfaces) if not specified -**How to avoid:** Always use explicit binding: `ports: ["127.0.0.1:8080:80"]` for private services -**Warning signs:** Services accessible from outside host, `netstat -tlnp` shows 0.0.0.0:8080 - -### Pitfall 3: Not Verifying Isolation Before Deployment -**What goes wrong:** Containers deployed, then discovered they can communicate across networks -**Why it happens:** Network isolation not tested in RED phase, only verified after setup -**How to avoid:** Write isolation tests FIRST (RED), then deploy containers (GREEN) -**Warning signs:** No test files in labs/lab-02-network/tests/ before writing docker-compose.yml - -### Pitfall 4: Confusion Between Container and Host Networking -**What goes wrong:** Students think `localhost` inside container reaches host services -**Why it happens:** `127.0.0.1` inside container refers to container, not host -**How to avoid:** Teach that `host.docker.internal` (Docker Desktop) or host gateway IP bridges the gap -**Warning signs:** "Connection refused" when container tries to connect to localhost services - -### Pitfall 5: Network Cleanup Between Tests -**What goes wrong:** Previous test networks interfere with new tests -**Why it happens:** Networks not removed between test runs, container references stale -**How to avoid:** Always run `docker compose down -v` to remove networks, include cleanup in tests -**Warning signs:** "Network already exists" errors, IP conflicts in subnet allocation -

-### Integration with Phase 2 (IAM Lab) - -**Phase 2 Integration Points:** -- Non-root containers from Lab 1 should be used in Lab 2 networks -- Docker socket access from Lab 1 enables network management in Lab 2 -- Test infrastructure patterns from Lab 1 (RED→GREEN→REFACTOR) apply to Lab 2 - -**Requiring Phase 2:** -- Student must have Docker access configured (Lab 1 success) -- Student must understand container execution (Lab 1 concept) - -**Building on Phase 2:** -- Lab 2 introduces complexity: multiple containers + networks (vs single container in Lab 1) -- Lab 2 requires verification of network isolation (new testing concept) -- Lab 2 introduces infrastructure as code (docker-compose.yml for networks) - -### Success Criteria Validation - -**Success Criteria 1:** Studente può creare reti Docker bridge isolate per simulare VPC e Subnets -- **How to verify:** Student creates docker-compose.yml with custom networks, verifies with `docker network ls` -- **Test command:** `bash tests/01-network-creation-test.sh` -- **Manual check:** `docker network inspect lab02-vpc-public` shows custom subnet - -**Success Criteria 2:** Reti private non espongono porte sull'host (max 127.0.0.1, mai 0.0.0.0) -- **How to verify:** Test checks docker-compose.yml for 0.0.0.0 bindings, verifies only 127.0.0.1 used -- **Test command:** `bash tests/inf-02-compliance-test.sh` -- **Manual check:** `netstat -tlnp` shows no 0.0.0.0 bindings for private services - -**Success Criteria 3:** Studente comprende il parallelismo tra Docker Bridge Networks e VPC cloud -- **How to verify:** Explanation document maps bridge networks → VPC, subnets → Subnets -- **Manual check:** Review `explanation/docker-network-vpc-parallels.md` -- **Test command:** None — conceptual understanding verified through documentation - -**Success Criteria 4:** Studente può verificare isolamento tra reti con test di connettività -- **How to verify:** Student runs ping/curl/netcat between containers, observes failures across networks -- **Test command:** `bash tests/02-isolation-verification-test.sh` -- **Manual check:** Student demonstrates `docker exec container1 ping container2` fails across networks - -**Success Criteria 5:** Lab include Documentazione Diátaxis completa con nomenclatura cloud -- **How to verify:** All 4 document types present, use VPC/subnet terminology consistently -- **Manual check:** File structure + content review for cloud terminology -- **Test command:** `find labs/lab-02-network -name "*.md" | grep -E "(tutorial|how-to|reference|explanation)"` - -## Open Questions - -1. **Should we simulate multiple Availability Zones?** - - What we know: AWS uses AZs for high availability, but Docker is single-host - - What's unclear: Would creating multiple "subnet-1a", "subnet-1b" networks be misleading? - - Recommendation: Include AZ naming convention for terminology learning, but document limitation (single host = no real AZ isolation) - -2. **How to handle DNS resolution testing in automated tests?** - - What we know: User-defined networks provide automatic DNS, default bridge doesn't - - What's unclear: Best way to test DNS in isolation verification? - - Recommendation: Use `docker exec container ping -c 1 other_container` which tests both DNS and connectivity - -3. **Should we implement NAT Gateway simulation?** - - What we know: AWS VPCs use NAT gateways for private subnet internet access - - What's unclear: Can Docker networks simulate NAT behavior without iptables complexity? - - Recommendation: Document as difference between local and cloud, don't implement (adds complexity without learning value) - -4. **What subnet CIDR pattern should we standardize on?** - - What we know: AWS uses 10.0.0.0/16 for VPC, 10.0.X.0/24 for subnets - - What's unclear: Should we match this exactly or use different ranges to avoid conflicts? - - Recommendation: Use 10.0.X.0/24 pattern matching AWS, document in ARCHITECTURE.md for future labs - -## Sources -

Lab Initialization:** -``` -Student → git checkout lab-XX-network - ↓ -Student → docker compose up -d - ↓ -Docker Compose → Parse compose.yml - ↓ -Docker Engine → Create networks (public, private-a, private-b) - ↓ -Docker Engine → Create volumes (data-b, logs) - ↓ -Docker Engine → Start containers (attach to networks) - ↓ -Containers → Internal DNS resolution (service names) -``` - -**2.

Containers in different networks cannot communicate unless explicitly connected. - -**When:** All network labs, security isolation demonstrations, multi-tier applications. - -**Example:** -```yaml -# docker-compose.yml -networks: - public-subnet: - driver: bridge - ipam: - config: - - subnet: 10.0.1.0/24 - private-subnet: - driver: bridge - internal: true # No internet access - ipam: - config: - - subnet: 10.0.2.0/24 - -services: - web-server: - networks: - - public-subnet - - private-subnet # Can talk to both - database: - networks: - - private-subnet # Only private -``` - -### Pattern 2: Resource Limits for Compute Quota - -**What:** Enforce CPU and memory limits at container level to simulate cloud instance sizes (t3.micro, t3.small, etc.). - -**When:** Compute labs, performance testing, resource isolation demos. - -**Example:** -```yaml -services: - app-tier: - deploy: - resources: - limits: - cpus: '0.5' # 0.5 vCPU = t3.micro equivalent - memory: 512M # 512MB RAM - reservations: - cpus: '0.25' - memory: 256M -``` - -### Pattern 3: Healthcheck for Service Readiness - -**What:** Use built-in HEALTHCHECK directive to ensure services are ready before dependent containers start. - -**When:** Multi-tier applications, database-dependent services, testing labs. - -**Example:** -```yaml -services: - postgres: - healthcheck: - test: ["CMD", "pg_isready", "-U", "admin"] - interval: 5s - timeout: 3s - retries: 5 - - app: - depends_on: - postgres: - condition: service_healthy -``` - -### Pattern 4: Volume Initialization with Seed Data - -**What:** Use init containers or volume pre-population to create databases with initial schema/data. - -**When:** Database labs, storage testing, demonstration environments. - -**Example:** -```yaml -services: - db-init: - image: postgres:15 - volumes: - - db-data:/var/lib/postgresql/data - - ./init.sql:/docker-entrypoint-initdb.d/init.sql - environment: - POSTGRES_DB: labdb - POSTGRES_USER: admin - POSTGRES_PASSWORD: secret -``` - -### Pattern 5: Test Container Pattern - -**What:** Create lightweight "probe" containers to verify network isolation and connectivity. - -**When:** Network labs, security testing, isolation verification. - -**Example:** -```yaml -# test-connectivity.yml -services: - probe-public: - image: nicolaka/netshoot - networks: - - public-subnet - command: | - sh -c "nc -zv web-server 80 && - nc -zv minio 9000 && - ! nc -zv database 5432" # Should fail -``` - -## Anti-Patterns to Avoid - -### Anti-Pattern 1: Using Default Bridge Network - -**What:** Not defining custom networks, letting containers use the default `bridge` network. - -**Why bad:** Containers communicate without restriction, no DNS resolution by name, poor security simulation. - -**Instead:** Always create named bridge networks with explicit subnets. - -### Anti-Pattern 2: Running Containers as Root - -**What:** Not specifying `user:` directive in Dockerfile or compose file. - -**Why bad:** Security vulnerability, violates cloud best practices (no root in production). - -**Instead:** Use `user: "1000:1000"` or create users in Dockerfile. - -### Anti-Pattern 3: Exposing All Ports to Host - -**What:** Using `ports: ["8080:8080"]` for all services. - -**Why bad:** Port conflicts, security exposure, breaks isolation simulation. - -**Instead:** Only expose public-facing services.

-### Pitfall 1: Data Loss on Container Restart - -**What goes wrong:** -Students lose all their work when containers are restarted or removed. Database data, uploaded files, and configuration changes disappear because data was written to the container's writable layer instead of volumes. - -**Why it happens:** -- Beginners don't understand Docker's layered filesystem -- Tutorials often skip volume configuration for simplicity -- The difference between `docker stop` vs `docker rm` isn't clear -- Anonymous volumes vs named volumes confusion - -**How to avoid:** -- Always use named Docker volumes for persistent data -- Explicitly declare volumes in `docker-compose.yml` under the top-level `volumes` key -- Teach volume lifecycle: volumes persist after container removal -- Use `--mount` flag syntax (more explicit) instead of `-v` for beginners - -**Warning signs:** -- No top-level `volumes:` section in docker-compose.yml -- Using inline volume paths like `./data:/app/data` without explaining persistence -- Labs that work once but fail on restart -- Students asking "where did my data go?" - -**Phase to address:** -Lab 1 (IAM & Sicurezza) - Introduce volume concepts early -Lab 4 (Storage) - Critical for object storage persistence -Lab 5 (Database) - Essential for database data persistence - ---- - -### Pitfall 2: Networking Confusion - Localhost vs Container Names - -**What goes wrong:** -Students try to connect to services using `localhost` or `127.0.0.1` instead of container service names. Connections fail because containers have isolated network stacks. - -**Why it happens:** -- Mental model from local development doesn't translate to containers -- Docker's embedded DNS isn't explained -- Students don't understand that each container has its own `localhost` -- Confusion between exposed ports and published ports - -**How to avoid:** -- Teach Docker's internal DNS resolution first -- Always use service names for inter-container communication -- Create network diagrams showing container isolation -- Explain `EXPOSE` (docs) vs `-p` (publish) difference clearly - -**Warning signs:** -- Connection refused errors when using localhost -- Students asking "why can't I connect to the database?" -- Mixing up `localhost` inside container vs `localhost` on host -- Port mapping confusion (internal vs external ports) - -**Phase to address:** -Lab 2 (Network) - Core networking concepts -Lab 5 (Database) - Application-to-database connections - ---- - -### Pitfall 3: OOM Killer - Resource Exhaustion - -**What goes wrong:** -Containers or the entire Docker daemon are killed by the kernel's OOM (Out Of Memory) killer. Students lose work and the lab environment becomes unstable. - -**Why it happens:** -- No memory limits set in docker-compose -- Multiple containers compete for host memory -- Students' machines have limited RAM (8GB or less) -- Memory leaks in student code go unchecked - -**How to avoid:** -- Always set `mem_limit` in docker compose for each service -- Use `deploy.resources.limits.memory` in compose file format v3+ -- Monitor with `docker stats` -- Teach students to check container resource usage -- Provide minimum host requirements (16GB RAM recommended) - -**Warning signs:** -- Containers randomly exit with code 137 -- Host system becomes slow -- `docker ps` shows containers restarting repeatedly -- System logs mention "OOM killer" - -**Phase to address:** -Lab 3 (Compute) - Resource limits are essential here -All labs - Enforce resource limits from the start - ---- - -### Pitfall 4: Security Misconfiguration - Running as Root - -**What goes wrong:** -Containers run as root by default, creating security vulnerabilities and permission issues with volume mounts. - -**Why it happens:** -- Docker's default behavior is root unless specified otherwise -- Base images often set `USER root` -- Beginners don't understand Linux user permissions -- Volume permission errors seem "easier" to fix with root - -**How to avoid:** -- Always specify `user:` directive in docker compose or Dockerfile -- Create non-root users in Dockerfiles -- Teach Linux permission basics alongside Docker -- Use Docker's user namespaces for advanced labs - -**Warning signs:** -- Permission denied errors with volumes -- Files created as root on host system -- Security warnings in `docker inspect` -- Running commands with `sudo` inside containers - -**Phase to address:** -Lab 1 (IAM & Sicurezza) - User permissions and security basics - ---- - -### Pitfall 5: Port Conflicts and Binding Issues - -**What goes wrong:** -Multiple students' labs conflict when using default ports. Services fail to start because ports are already in use. - -**Why it happens:** -- Hardcoded default ports (3306, 5432, 8080, etc.) -- Multiple labs running simultaneously -- Not teaching port mapping flexibility -- Students don't know how to check occupied ports - -**How to avoid:** -- Use non-standard ports in examples (e.g., 5433 instead of 5432) -- Teach students to check port usage: `netstat -tuln` or `ss -tuln` -- Document all port mappings in lab materials -- Provide scripts to detect port conflicts - -**Warning signs:** -- "port already allocated" errors -- Services failing to start silently -- Students reporting "it worked yesterday but not today" -- Multiple labs can't run simultaneously - -**Phase to address:** -Lab 2 (Network) - Port mapping and exposure -All labs - Use unique port ranges per lab - ---- - -### Pitfall 6: depends_on Without Readiness Checks - -**What goes wrong:** -Services start but fail because dependencies aren't ready. Applications crash trying to connect to databases that are still initializing. - -**Why it happens:** -- `depends_on` only waits for containers to start, not be ready -- Databases need time to initialize (can take 10-30 seconds) -- No healthcheck or readiness probe configured -- Students assume "started" = "ready to accept connections" - -**How to avoid:** -- Implement healthchecks for all services -- Use restart policies with delays -- Teach the difference between "running" and "healthy" -- Provide example healthcheck scripts for common services - -**Warning signs:** -- Intermittent connection failures on lab startup -- "Connection refused" errors that go away with manual retry -- Services exiting and restarting -- Need to manually restart containers to make things work - -**Phase to address:** -Lab 3 (Compute) - Health checks and service readiness -Lab 5 (Database) - Database initialization timing - ---- - -### Pitfall 7: Orphaned Resources - Disk Space Exhaustion - -**What goes wrong:** -Students' disk space fills up with stopped containers, unused volumes, and dangling images. Docker becomes unusable. - -**Why it happens:** -- Students never clean up resources -- No teaching of `docker system prune` -- Volumes aren't removed when containers are deleted -- Image layers accumulate during development - -**How to avoid:** -- Teach cleanup commands in every lab -- Provide cleanup scripts -- Use `--rm` flag for one-off containers -- Explain volume lifecycle and manual removal -- Monitor disk usage in lab instructions - -**Warning signs:** -- Disk space warnings on host system -- `docker system df` shows large unused space -- Slow container startup due to image bloat -- "No space left on device" errors - -**Phase to address:** -Lab 1 (IAM & Sicurezza) -

use specific versions | -| Exposing all ports | "It just works" | Security issues, port conflicts | NEVER - expose only what's needed | - -## Integration Gotchas - -Common mistakes when connecting to external services. - -| Integration | Common Mistake | Correct Approach | -|-------------|----------------|------------------| -| MinIO (S3) | Using AWS endpoint `s3.amazonaws.com` | Use `http://localhost:9000` or container service name | -| MinIO Console | Confusing port 9000 (API) with 9001 (Console) | Document both ports clearly, separate service configs | -| PostgreSQL | Using default port 5432 (causes conflicts) | Use 5433 or other non-standard port | -| MySQL | Not setting `MYSQL_ROOT_PASSWORD` env var | Always set required environment variables | -| Redis | Using default port 6379 (may conflict) | Use non-standard port or proper networking | -| Networks | Using legacy `--link` flag | Use user-defined networks and service names | -| Volumes | Bind mounting to non-existent host paths | Create host directories first or use named volumes | -| DNS | Using `/etc/hosts` inside containers | Use Docker's embedded DNS with service names | - -## Performance Traps - -Patterns that work at small scale but fail as usage grows. - -| Trap | Symptoms | Prevention | When It Breaks | -|------|----------|------------|----------------| -| No resource limits | Works with 1-2 containers, host crashes at 5+ | Always set CPU and memory limits | 3-5 containers on 8GB RAM | -| Single bridge network | Fine for simple apps, confusing for complex | Use multiple networks for isolation | 5+ services with different security needs | -| tmpfs for data | Fast but data loss on restart | Use named volumes for persistence | Immediately on container restart | -| Logging to json-file without rotation | Works initially, disk fills up | Set `max-size` and `max-file` options | After running labs repeatedly | -| Building images in Compose | Slow rebuilds, large layers | Use multi-stage builds, .dockerignore | After 3-4 iterations | -| Running everything on default network | Works until naming conflicts arise | Use custom networks per lab | When running multiple labs simultaneously | - -## Security Mistakes - -Domain-specific security issues beyond general web security. - -| Mistake | Risk | Prevention | -|---------|------|------------| -| Mounting Docker socket (`/var/run/docker.sock`) | Container breakout, root on host | NEVER do this in educational context | -| Running containers as root | Privilege escalation vulnerabilities | Always use `user:` directive | -| Exposing all ports to 0.0.0.0 | Services accessible externally | Bind to 127.0.0.1 or use internal networks | -| Using default credentials | Easy unauthorized access | Require password changes, document security | -| Sharing host PID namespace | Container can see host processes | Never use `pid: host` in labs | -| Ignoring cgroups | No resource isolation = DoS potential | Always set resource limits | -| Using `--privileged` flag | Complete host access | NEVER acceptable, teaches bad practices | -| Not using AppArmor/SELinux profiles | Missing security layer | Enable when available, document why | - -## UX Pitfalls - -Common user experience mistakes in this domain. - -| Pitfall | User Impact | Better Approach | -|---------|-------------|-----------------| -| Silent failures | Students don't know what went wrong | Always provide error messages and logs | -| No progress indicators | Students think labs are broken | Show startup progress, especially for databases | -| Hidden dependencies | Labs fail mysteriously | List all prerequisites clearly, check at startup | -| Complex YAML errors | Students stuck on syntax | Validate YAML before running, provide examples | -| No rollback capability | Mistakes require starting over | Git version control, snapshot instructions | -| Missing cleanup steps | Accumulating cruft, confusion | Provide cleanup scripts for each lab | -| Unclear parallelisms | Students don't see the point | Explicitly map Docker concepts to AWS services | -| Assuming prior knowledge | Beginners get lost | Provide background reading, glossary of terms | - -## "Looks Done But Isn't" Checklist - -Things that appear complete but are missing critical pieces. - -- [ ] **Volume Persistence:** Often missing named volume declarations — verify data survives `docker down` and `docker up` -- [ ] **Network Isolation:** Often missing network per lab — verify containers can't accidentally talk between labs -- [ ] **Health Checks:** Often missing readiness verification — verify `docker ps` shows "healthy" not just "running" -- [ ] **Resource Limits:** Often missing CPU/memory constraints — verify `docker stats` shows limits -- [ ] **Cleanup Scripts:** Often missing tear-down instructions — verify `docker system df` is clean after lab -- [ ] **Error Handling:** Often missing graceful failure modes — verify lab handles common errors (port conflicts, missing volumes) -- [ ] **Cloud Parallels:** Often missing explicit mappings — verify each Docker component maps to a specific AWS service -- [ ] **Diátaxis Documentation:** Often missing explanation documents — verify each lab has all 4 document types - -## Recovery Strategies - -When pitfalls occur despite prevention, how to recover. - -| Pitfall | Recovery Cost | Recovery Steps | -|---------|---------------|----------------| -| Data loss from missing volumes | HIGH | Rebuild from scratch, add volumes, restore from backup if available | -| OOM killer crash | MEDIUM | Add memory limits to all services, restart Docker daemon, free host memory | -| Port conflicts | LOW | Change port mappings, kill conflicting processes, restart services | -| Permission errors | MEDIUM | Add `user:` directive, chown volume directories, rebuild containers | -| Network connectivity issues | LOW | Verify service names, check network attachment, ping between containers | -| Disk space exhaustion | HIGH | Run `docker system prune -a`, remove unused volumes, clear build cache | -| Orphaned containers | LOW | Run `docker container prune`, remove stopped containers manually | -

-**Project:** Laboratori Cloud - Corso Soluzioni Cloud -**Domain:** Educational platform for cloud with practical Docker-based labs -**Researched:** 2026-03-24 -**Confidence:** HIGH - -## Executive Summary - -This is an educational platform for teaching cloud concepts through local Docker-based laboratories, eliminating cloud costs while maintaining professional-grade learning outcomes. Expert-built cloud education platforms use sandbox environments with clear service mappings, explicit troubleshooting guidance, and structured skill progression. The recommended approach combines Docker's container isolation with a rigorous pedagogical framework (Diátaxis) and test-driven infrastructure methodology. - -The research indicates that successful cloud labs require: (1) zero-cost local environments using Docker to simulate AWS services, (2) explicit Docker-to-cloud service mappings (Docker Networks → VPC, MinIO → S3, PostgreSQL → RDS), (3) comprehensive documentation following the Diátaxis framework (Tutorial, How-to, Reference, Explanation) for every lab, and (4) test-driven infrastructure where students write validation scripts before implementing solutions. The key differentiator is the "safety-first" approach that teaches security best practices as core habits rather than afterthoughts. - -Critical risks include data loss from improper volume configuration, OOM killer crashes from missing resource limits, and security vulnerabilities from running containers as root. These are mitigated through mandatory named volumes, enforced CPU/memory limits, and non-root user directives in all lab configurations. The most significant pedagogical risk is students failing to understand the cloud parallels, which is addressed through explicit Explanation documents mapping every Docker component to its AWS equivalent. - -## Key Findings - -### Recommended Stack - -**Core technologies:** -- Docker Engine 28.0+ and Docker Compose V2.36.2+ — Container orchestration foundation, standard market choice with native isolation and rootless support -- PostgreSQL 18.x or MySQL 9.x — Relational database simulating RDS/Aurora with ACID compliance -- MinIO RELEASE.2025+ — S3-compatible object storage with 100% API compatibility for local simulation -- Docker Bridge Networks + iptables — Network isolation simulating VPC/Subnets with NAT and firewall rules - -**Critical stack decisions:** -- Avoid Docker Compose V1 (deprecated) — use V2 integrated syntax -- Always use named volumes (not bind mounts) for data persistence -- Enforce resource limits via `deploy.resources.limits` in all services -- Use non-root users via `user:` directive or Dockerfile USER command - -### Expected Features - -**Must have (table stakes):** -- Step-by-step instructions with exact commands — students need unambiguous guidance -- Working test environment — Docker Compose must start without errors -- Work verification via test scripts — automated validation (curl, nc, docker ps) -- Explicit cloud ↔ local parallels — every Docker concept maps to AWS service -- Basic troubleshooting guides — common errors and solutions -- Clear prerequisites — Docker versions, OS requirements, minimum resources -- Environment restoration — reset/cleanup commands for each lab -- Estimated completion time — 1-3 hours per lab typical - -**Should have (competitive differentiators):** -- ZERO cloud costs — only local Docker, no AWS/Azure accounts -- Safety-first excellence — least privilege, network isolation, resource limits taught as core habits -- Complete Diátaxis framework — Tutorial + How-to + Reference + Explanation for EVERY lab -- Test-Driven Infrastructure (TDI) — RED→GREEN→REFACTOR methodology for infrastructure -- Designed incrementality — Labs 1-5 build progressively to complete system -- "Little often" approach — small concepts, frequent practice to avoid overwhelm -- Explicit Double Check — pre-commit checklists for each laboratory -- 1:1 architecture mapping — Docker Networks → VPC, MinIO → S3, PostgreSQL → RDS -- Included test scripts — students learn to validate their own work -- Professional Git workflow — Conventional Commits, per-lab branches - -**Defer (v2+):** -- Official solutions — add after student requests for self-verification -- Auto-correction scripts — helpful but not essential for learning -- Optional challenge labs — for advanced students who find core too easy -- Multi-cloud versions — AWS focus first, Azure/GCP parallels later -- Pre-configured VM — only if setup issues become widespread - -### Architecture Approach - -**Major components:** -1. Docker Engine — Container lifecycle, image management, network isolation -2. Docker Compose — Multi-container orchestration per lab, service dependencies -3. Bridge Networks — VPC/Subnet simulation with network isolation and DNS resolution -4. Named Volumes — Persistent data storage (DB, Object Storage) with data isolation -5. Test Containers — Network connectivity verification and service health checks -6. Student Workspace — Git repo, lab documentation, test scripts - -**Key architectural patterns:** -- Network isolation via multiple bridge networks simulating VPC public/private subnets -- Resource limits enforcing CPU/memory quotas matching cloud instance sizes -- Healthcheck directives ensuring service readiness before dependencies start -- Volume initialization with seed data for database labs -- Test container pattern for isolation and connectivity verification - -**Critical anti-patterns to avoid:** -- Default bridge network (no isolation, poor DNS) -- Running as root (security vulnerability, violates cloud best practices) -- Exposing all ports to host (port conflicts, security exposure) -- Anonymous volumes (difficult management, can't backup easily) -- No resource limits (unrealistic behavior, no quota simulation) - -### Critical Pitfalls - -1. **Data loss on container restart** — Always use named Docker volumes with explicit declarations in top-level `volumes:` section; teach volume lifecycle and persistence early - -2. **Networking confusion (localhost vs container names)** — Teach Docker's internal DNS resolution first; always use service names for inter-container communication; create network diagrams showing container isolation - -3. **OOM killer (resource exhaustion)** — Always set `mem_limit` and CPU limits in docker-compose; monitor with `docker stats`; recommend 16GB RAM minimum for host - -4. **Running as root** — Always specify `user:` directive in docker compose or Dockerfile; teach Linux permission basics alongside Docker; never use `--privileged` flag - -5. **Port conflicts and binding issues** — Use non-standard ports in examples (5433 instead of 5432); teach students to check port usage; document all port mappings; provide conflict detection scripts - -6. **depends_on without readiness checks** — Implement healthchecks for all services; use restart policies with delays; teach difference between "running" and "healthy" - -7. **Orphaned resources (disk space exhaustion)** — Teach cleanup commands in every lab; provide cleanup scripts; use `--rm` flag for one-off containers; explain volume lifecycle - -## Implications for Roadmap - -Based on research, suggested phase structure: - -### Phase 1: Lab 01 - IAM & Security -**Rationale:** Foundation for all subsequent labs; introduces Docker basics, Linux permissions, volume concepts, and security-first mindset that prevents critical pitfalls #1, #3, #4 -**Delivers:** Docker environment setup, user permissions basics, named volume introduction, cleanup procedures -**Addresses:** Table stakes (step-by-step instructions, working environment, troubleshooting, prerequisites) -**Avoids:** Data loss on restart, running as root, orphaned resources, permission errors -**Features:** Framework Diátaxis (4 docs), test scripts with TDI methodology, Git workflow, cloud parallels (Linux users → IAM Users) - -### Phase 2: Lab 02 - Network -**Rationale:** Core cloud concept (VPC) and critical prerequisite for Labs 3-5; addresses networking confusion (pitfall #2) and port conflicts (pitfall #5) -**Delivers:** Docker bridge networks, VPC/subnet simulation, DNS resolution, network isolation, port mapping -**Uses:** Docker Bridge Networks, iptables for NAT/firewall simulation -**Implements:** Network isolation pattern, test container pattern for connectivity verification -**Avoids:** Networking confusion, port conflicts, default bridge network anti-pattern -**Features:** Network diagrams, isolation verification tests, routing table explanations - -### Phase 3: Lab 03 - Compute -**Rationale:** Simulates EC2/VM with resource limits; introduces healthchecks preventing pitfall #6; builds on Lab 2 networking -**Delivers:** Containers with CPU/memory limits, healthcheck implementation, service dependencies -**Uses:** Resource limits pattern, healthcheck pattern -**Implements:** Compute quota simulation, service readiness verification -**Avoids:** OOM killer, depends_on without readiness checks, no resource limits -**Features:** Resource monitoring with docker stats, healthcheck test scripts - -### Phase 4: Lab 04 - Storage -**Rationale:** Simulates S3 (MinIO) + Block Storage (Volumes); volume persistence is critical (pitfall #1); independent from Lab 3 but depends on Lab 2 networking -**Delivers:** MinIO S3-compatible storage, named volume management, volume initialization with seed data -**Uses:** Docker Volumes, MinIO for S3 simulation -**Implements:** Volume initialization pattern, object storage access patterns -**Avoids:** Data loss from missing volumes, anonymous volumes, tmpfs for persistent data -**Features:** S3 API compatibility demonstration, volume persistence verification tests - -### Phase 5: Lab 05 - Database -**Rationale:** Culmination integrating all concepts (Network + Storage + Compute); simulates RDS in private network; demonstrates multi-tier architecture -**Delivers:** PostgreSQL/MySQL in isolated network, application-to-database connections, cross-network communication, data persistence -**Uses:** PostgreSQL/MySQL, named volumes, private networks from Lab 2 -**Implements:** Multi-tier architecture, complete VPC simulation with public/private subnets -**Avoids:** Networking confusion, depends_on without readiness, data loss -**Features:** Complete cloud architecture (VPC + RDS + S3), comprehensive integration tests - -### Phase Ordering Rationale - -- **Lab 1 first** because it establishes foundational security practices and Docker basics that all subsequent labs depend on; skipping this would cause permission errors and security issues throughout -- **Lab 2 before Labs 3-5** because network isolation is a prerequisite for realistic compute, storage, and database simulation; cloud services depend on VPC networking -- **Lab 3 before Lab 5** because compute patterns (healthchecks, resource limits) are needed for database-dependent applications -- **Lab 4 before Lab 5** because storage persistence concepts are needed for database data persistence -- **Lab 5 last** because it integrates all previous concepts (Network + Compute + Storage) into a complete multi-tier cloud architecture - -### Research Flags - -**Phases likely needing deeper research during planning:** -- **Phase 2 (Network):** Complex iptables rules for NAT Gateway simulation may require targeted research during implementation -- **Phase 5 (Database):** Database initialization timing and cross-network connection pooling may need validation research - -**Phases with standard patterns (skip research-phase):** -- **Phase 1 (IAM):** Well-documented Docker security patterns, standard Linux permission practices -- **Phase 3 (Compute):** Established resource limit patterns in Docker Compose, standard healthcheck implementations -- **Phase 4 (Storage):** MinIO documentation is comprehensive, Docker volume patterns are standard - -## Confidence Assessment - -| Area | Confidence | Notes | -|------|------------|-------| -| Stack | HIGH | All technologies verified against official documentation (Docker Engine v28, Compose V2, PostgreSQL 18, MinIO RELEASE.2025) | -| Features | MEDIUM | Based on competitor analysis and educational best practices;

Obiettivo del Progetto -Creare materiale didattico tecnico, strutturato secondo il framework **Diátaxis**, per un corso pratico sulle tecnologie Cloud. I laboratori simuleranno i servizi core di un cloud provider (IAM, Network, Compute, Storage, Database) utilizzando un ambiente locale basato su macchine virtuali (KVM/VirtualBox) e Docker. - -L'output generato dall'LLM dovrà avere un tono diretto, semplice e rigorosamente tecnico. - -## 2. Regole d'Ingaggio per l'Agente LLM (Core Principles) -L'agente LLM incaricato di generare il contenuto deve rispettare tassativamente i seguenti principi nella stesura del codice e dei testi: - -* **Spec-Driven:** Ogni modulo deve iniziare con le specifiche tecniche chiare dell'architettura da realizzare. -* **Infrastructure-TDD (Test-Driven Development):** Prima di fornire i file di configurazione (`docker-compose.yml`, `Dockerfile`, script bash), l'LLM deve fornire i test o i comandi di validazione. Bisogna definire "come testiamo che funzioni" prima di scriverlo. -* **Le 3 Regole d'Oro:** - 1. **Safety first:** Il codice e le architetture devono partire dal principio del minimo privilegio (reti isolate, permessi restrittivi, niente root se non necessario). - 2. **Little often:** I laboratori devono essere incrementali. Piccoli step testabili. - 3. **Double check:** Ogni fase deve concludersi con una verifica esplicita dello stato dell'infrastruttura (connettività, log, processi). -* **Git Flow Avanzato:** Il tutorial deve guidare l'allievo nel versionamento. L'LLM deve suggerire commit atomici utilizzando le convenzioni dei **Conventional Commits** (es. `feat: add private vpc network`, `test: verify db connection via pg_isready`) e indicare le strategie di branching ottimali per isolare i laboratori. - -## 3. Struttura dei Contenuti (Framework Diátaxis) -Per ogni modulo (Lab), l'LLM dovrà produrre 4 artefatti distinti: - -1. **Tutorials (Learning-oriented):** La guida passo-passo che prende per mano l'allievo. Segue la regola del *little often*. Contiene le istruzioni pratiche, i comandi Git e le verifiche (*double check*). -2. **How-to Guides (Goal-oriented):** Ricettari per compiti specifici e slegati dal flusso principale (es. "Come resettare l'ambiente Docker", "Come generare una nuova coppia di chiavi SSH sicure"). -3. **Reference (Information-oriented):** Specifiche tecniche pure. I file `docker-compose.yml` completi, mappe delle reti IP assegnate, tabelle delle porte esposte, spiegazione nuda e cruda dei parametri usati. -4. **Explanation (Understanding-oriented):** Il raccordo concettuale. Spiegazione del parallelismo tra l'infrastruttura locale simulata e i servizi managed reali (es. "Perché questo container MinIO si comporta come un bucket AWS S3"). - -## 4. Specifiche dei Moduli (I Laboratori) - -### Lab 1: IAM & Sicurezza -* **Obiettivo:** Gestione accessi e perimetrazione. -* **Componenti Locali:** Utenti Linux, gruppi, chiavi SSH, permessi Docker socket. -* **Parallelismo Cloud:** AWS IAM, Azure AD, RBAC. -* **Spec-Driven & TDD:** Il test deve provare a eseguire un container privilegiato con un utente non autorizzato e fallire. -* **Git:** Branch `lab-01-iam`. - -### Lab 2: Network -* **Obiettivo:** Isolamento delle risorse e routing. -* **Componenti Locali:** Docker Networks (bridge), configurazione `iptables` per NAT. -* **Parallelismo Cloud:** VPC, Subnets pubbliche/private, Security Groups, NAT Gateway. -* **Spec-Driven & TDD:** I test consistono nell'avviare container sonda (Alpine/Busybox) ed eseguire `ping` e `nc` per verificare che la rete privata non esca su internet se non tramite il NAT, e che le due reti non comunichino senza regole esplicite. -* **Git:** Branch `lab-02-network`. - -### Lab 3: Compute -* **Obiettivo:** Erogazione della potenza di calcolo e containerizzazione. -* **Componenti Locali:** VM (per concetti Hypervisor/IaaS) + Docker (CaaS). Web server leggero (Nginx/Node.js). -* **Parallelismo Cloud:** EC2, Compute Engine, ECS, Fargate. -* **Spec-Driven & TDD:** Configurare i limiti (`cpus`, `mem_limit`) nel Compose. Il test deve essere uno stress-test che causa l'OOM (Out Of Memory) kill del container per dimostrare l'enforcement delle quote. -* **Git:** Branch `lab-03-compute`. - -### Lab 4: Storage -* **Obiettivo:** Persistenza dei dati e object storage. -* **Componenti Locali:** Docker Volumes (Block) e container MinIO (Object). -* **Parallelismo Cloud:** EBS (Block), S3 (Object). -* **Spec-Driven & TDD:** Test API via client CLI (`mc`) per creare un bucket e caricare un file testuale su MinIO. -* **Git:** Branch `lab-04-storage`. - -### Lab 5: Database -* **Obiettivo:** Simulazione di un database gestito e disaccoppiato. -* **Componenti Locali:** Container PostgreSQL/MySQL allocato nella VPC privata con volume persistente. -* **Parallelismo Cloud:** Amazon RDS, Cloud SQL. -* **Spec-Driven & TDD:** Un container applicativo (VPC pubblica) deve eseguire uno script di verifica connessione al DB (VPC privata) all'avvio. Se la connessione fallisce, l'app non si espone (*safety first*). -* **Git:** Branch `lab-05-database`. -
