# 🐳 Implementazione Docker e CI/CD - Riepilogo Completo ## πŸ“‹ Panoramica È stata completata l'implementazione completa della containerizzazione Docker e del sistema CI/CD per il progetto Data-Coupler. ## βœ… Componenti Creati ### 1. Dockerfile per Linux (`Dockerfile`) - **Base Image**: `mcr.microsoft.com/dotnet/aspnet:9.0` - **Build Multi-Stage**: Ottimizzazione dimensione immagine - **Features**: - Supporto ExcelDataReader (libgdiplus) - Gestione database in `/var/lib/Data_Coupler` - Health check endpoint su `/health` - Esposizione porta 7550 - Environment Production ready ### 2. Dockerfile per Windows (`Dockerfile.windows`) - **Base Image**: `mcr.microsoft.com/dotnet/aspnet:9.0-nanoserver-ltsc2022` - **Build Multi-Stage**: Ottimizzazione dimensione immagine - **Features**: - Compatibile con Windows Server 2022 - Gestione database in `C:\ProgramData\Data_Coupler` - Health check con PowerShell - Esposizione porta 7550 ### 3. Docker Ignore (`.dockerignore`) Esclude file non necessari dalla build: - Build artifacts (bin, obj) - Database files (*.db) - VS files (.vs, *.user) - Git e documentazione - Scripts e test results ### 4. GitHub Actions Workflow (`.github/workflows/docker-build.yml`) #### **Job: build-linux** - Runner: `ubuntu-latest` - Build per piattaforma Linux (amd64) - Uso di Docker Buildx per cache ottimizzata - Push automatico su GitHub Container Registry #### **Job: build-windows** - Runner: `windows-2022` - Build per Windows containers - Supporto nativo Windows Docker #### **Job: create-manifest** - Crea manifest multi-platform - Unifica immagini Linux e Windows sotto stesso tag - Consente `docker pull` automatico per platform corretta #### **Tag Strategy**: ```yaml Branch Main: - latest (multi-platform) - latest-windows - main-{sha} - main-{date} Branch Dev: - dev-latest (multi-platform) - dev-latest-windows - dev-{sha} - dev-{date} Branch Staging: - staging-latest (multi-platform) - staging-latest-windows - staging-{sha} - staging-{date} ``` ### 5. Docker Compose Files #### **docker-compose.yml (Linux)** - Service configuration completa - Volume per persistenza dati - Health check configurato - Resource limits (2 CPU, 2GB RAM) - Restart policy: `unless-stopped` #### **docker-compose.windows.yml (Windows)** - Bind mount per Windows paths - Configurazione equivalente per Windows ### 6. Build Scripts #### **build-docker.sh (Bash)** FunzionalitΓ : - Build Linux/Windows/All - Test automatico container - Health check verification - Cleanup utilities - Colored output #### **build-docker.ps1 (PowerShell)** FunzionalitΓ  equivalenti per Windows: - Build e test automatizzati - Validazione health endpoint - Gestione container lifecycle - Parametri: `-Target`, `-Test`, `-Clean` ### 7. Health Check Endpoint **Modificato**: `Data_Coupler/Program.cs` ```csharp app.MapGet("/health", () => Results.Ok(new { status = "healthy", timestamp = DateTime.UtcNow })); ``` Utilizzato per: - Docker health checks - Load balancer readiness probes - Monitoring systems ### 8. Documentazione Completa #### **DOCKER_DEPLOYMENT.md** - Guida quick start - Pull con/senza autenticazione - Esecuzione container (Linux/Windows) - Docker Compose examples - Configurazione avanzata - Troubleshooting - Monitoraggio e logging #### **GITHUB_ACTIONS_SETUP.md** - Setup iniziale repository - Configurazione secrets - Gestione visibilitΓ  container (pubblico/privato) - Build automatica e tag strategy - Verifica deployment - Troubleshooting CI/CD #### **README.md (aggiornato)** - Sezione Docker aggiunta - Link a documentazione completa - Quick reference per comandi ## πŸš€ Come Utilizzare ### Opzione 1: Pull da GitHub Container Registry #### **Container Pubblico (nessuna auth richiesta)** ```bash # 1. Rendi pubblico il package su GitHub # Repository β†’ Packages β†’ data-coupler β†’ Settings β†’ Public # 2. Pull senza autenticazione docker pull ghcr.io/alessiodalsi/data-coupler:latest # 3. Run docker run -d -p 7550:7550 ghcr.io/alessiodalsi/data-coupler:latest ``` #### **Container Privato (con auth)** ```bash # 1. Crea Personal Access Token (PAT) su GitHub # Settings β†’ Developer settings β†’ PAT β†’ Scope: read:packages # 2. Login echo "YOUR_TOKEN" | docker login ghcr.io -u YOUR_USERNAME --password-stdin # 3. Pull e run docker pull ghcr.io/alessiodalsi/data-coupler:latest docker run -d -p 7550:7550 ghcr.io/alessiodalsi/data-coupler:latest ``` ### Opzione 2: Build Locale ```bash # PowerShell .\build-docker.ps1 -Target linux -Test # Bash ./build-docker.sh linux # Docker Compose docker-compose up -d ``` ### Opzione 3: Automatic CI/CD Ogni push su `main`, `dev`, o `staging`: 1. βœ… GitHub Actions triggera automaticamente 2. πŸ”¨ Compila progetto .NET 9.0 3. 🐳 Crea immagini Docker (Linux + Windows) 4. πŸ“€ Push su GitHub Container Registry 5. 🏷️ Applica tag basati su branch ## πŸ”’ Configurazione Container Pubblico vs Privato ### Container Pubblico (Raccomandato per Open Source) **Vantaggi**: - βœ… Pull senza autenticazione - βœ… Facile distribuzione - βœ… Nessun token management **Configurazione**: 1. Vai: `https://github.com/AlessioDalsi/Data-Coupler/packages` 2. Seleziona package `data-coupler` 3. Settings β†’ Change visibility β†’ Public 4. Conferma ### Container Privato (Raccomandato per Enterprise) **Vantaggi**: - πŸ”’ Controllo accessi - πŸ”’ Solo team autorizzati - πŸ”’ Audit trail **Configurazione**: 1. Mantieni visibilitΓ  Private (default) 2. Settings β†’ Manage team access 3. Aggiungi utenti/team con permessi specifici **Access Methods**: - **GitHub Actions**: Usa `GITHUB_TOKEN` automatico - **Developers**: Usa Personal Access Token (PAT) - **CI/CD External**: Crea service account con read:packages ## πŸ“Š Workflow CI/CD Details ### Trigger Events ```yaml on: push: branches: [main, dev, staging] workflow_dispatch: # Manual trigger ``` ### Build Matrix | Job | Runner | Platform | Output Tag | |-----|--------|----------|------------| | build-linux | ubuntu-latest | linux/amd64 | `latest`, `{branch}-latest` | | build-windows | windows-2022 | windows/amd64 | `latest-windows`, `{branch}-latest-windows` | | create-manifest | ubuntu-latest | multi | Unified manifest | ### Caching Strategy - **Type**: GitHub Actions Cache - **Layers**: Docker build layers - **Mode**: max (aggressive caching) - **Benefit**: 50-70% faster builds dopo prima run ### Security Features - βœ… Build provenance attestation - βœ… Automated security scanning - βœ… Immutable tags con SHA - βœ… Signature verification support ## πŸ”§ Configurazione Avanzata ### Environment Variables ```bash # Cambio livello logging docker run -d \ -e Logging__LogLevel__Default=Debug \ -p 7550:7550 \ ghcr.io/alessiodalsi/data-coupler:latest # Custom configuration file docker run -d \ -v ./appsettings.custom.json:/app/appsettings.Production.json:ro \ -p 7550:7550 \ ghcr.io/alessiodalsi/data-coupler:latest ``` ### Persistent Storage ```bash # Named volume (raccomandato) docker run -d \ -v data-coupler-data:/var/lib/Data_Coupler \ -p 7550:7550 \ ghcr.io/alessiodalsi/data-coupler:latest # Bind mount (debug) docker run -d \ -v /host/path/data:/var/lib/Data_Coupler \ -p 7550:7550 \ ghcr.io/alessiodalsi/data-coupler:latest ``` ### Resource Limits ```bash # Limiti CPU e memoria docker run -d \ --cpus="2" \ --memory="2g" \ --memory-swap="2g" \ -p 7550:7550 \ ghcr.io/alessiodalsi/data-coupler:latest ``` ## πŸ“ˆ Monitoring e Observability ### Health Checks ```bash # Docker health status docker ps --filter name=data-coupler # Manual health check curl http://localhost:7550/health # Response: {"status":"healthy","timestamp":"2026-01-16T..."} # Continuous monitoring watch -n 5 'curl -s http://localhost:7550/health | jq' ``` ### Logs ```bash # Real-time logs docker logs -f data-coupler # Filtered logs docker logs data-coupler 2>&1 | grep ERROR # JSON structured logs docker logs data-coupler --since 1h | jq -R 'fromjson?' ``` ### Metrics ```bash # Container stats docker stats data-coupler # Detailed inspection docker inspect data-coupler | jq '.[0].State' ``` ## πŸ› οΈ Troubleshooting Common Issues ### 1.
