Implement Lab 02 with Docker bridge networks simulating VPC/Subnets. Test Infrastructure (RED phase): - 6 bash test scripts for network creation, isolation, INF-02 compliance - Fail-fast orchestration with run-all-tests.sh - Quick validation script for development Documentation (Diátaxis framework): - 3 tutorials: VPC creation, container deployment, isolation verification - 4 how-to guides: create network, inspect config, test isolation, cleanup - 3 reference docs: Docker network commands, Compose syntax, VPC mapping - 1 explanation: Docker ↔ VPC parallels (PARA-01/02/03/04) Infrastructure (GREEN phase): - docker-compose.yml with VPC networks (10.0.1.0/24, 10.0.2.0/24) - 5 services: web, app, db, test-public, test-private - INF-02 compliant: 127.0.0.1 bindings only, no 0.0.0.0 - Private network with --internal flag - Multi-homed app container (public + private networks) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

How-To: Creare una Rete Docker Personalizzata
Guida rapida per creare reti Docker bridge con subnet personalizzate.
Comando Rapido
# Crea rete con subnet personalizzata
docker network create --driver bridge --subnet 10.0.1.0/24 --gateway 10.0.1.1 my-custom-network
Sintassi Completa
docker network create [OPTIONS] NETWORK
Options:
--driver bridge # Driver di rete (default: bridge)
--subnet SUBNET # CIDR block (es. 10.0.1.0/24)
--gateway GATEWAY # Gateway IP (es. 10.0.1.1)
--internal # Isola la rete (no accesso esterno)
--attachable # Permette container stand-alone di collegarsi
Esempi
Rete Pubblica Standard
docker network create --driver bridge \
--subnet 10.0.1.0/24 \
--gateway 10.0.1.1 \
my-public-network
Rete Privata Isolata
docker network create --driver bridge \
--subnet 10.0.2.0/24 \
--gateway 10.0.2.1 \
--internal \
my-private-network
Rete Multi-Subnet
docker network create --driver bridge \
--subnet=10.0.10.0/24 \
--gateway=10.0.10.1 \
--subnet=10.0.20.0/24 \
--gateway=10.0.20.1 \
my-multi-network
Verifica
# Lista reti
docker network ls
# Ispeziona rete
docker network inspect my-custom-network
# Rimuovi rete
docker network rm my-custom-network
