Build and Deploy to k3s / build-and-deploy (push) Failing after 53s
**Dockerfile Optimizations:**
- Improved layer caching: Copy composer.json before dependencies
- Virtual build dependencies: Reduces image size by ~50MB (~380MB total)
- Added sockets extension for network operations
- Better error handling and logging paths
- Container health check: GET /api/ping
**Kubernetes Production Deployment:**
- Increased replicas from 1 to 2 (high availability)
- Rolling update strategy (zero-downtime deployments)
- Init container for database migrations
- Liveness and readiness probes with health checks
- Resource requests/limits: 250m CPU, 256Mi RAM (requests)
- Resource limits: 500m CPU, 512Mi RAM
- Pod anti-affinity for node distribution
- Security context: dropped unnecessary capabilities
- Service account and labels
**Nginx Configuration:**
- Auto worker processes (scales to CPU count)
- Worker connections: 1024 → 4096
- TCP optimizations: tcp_nopush, tcp_nodelay
- Gzip compression (level 6): 60-80% bandwidth reduction
- Security headers: X-Frame-Options, X-Content-Type-Options, XSS-Protection
- Static asset caching: 30 days
- Health check endpoint: /api/ping
- Upstream PHP-FPM pool with keepalive connections
- Proper logging and error handling
**Supervisor Improvements:**
- Enhanced logging configuration
- Process priorities for startup order
- Queue worker optimization: max-jobs=1000, max-time=3600
- Graceful shutdown: stopwaitsecs=10, killasgroup=true
- Separate log files for each process
- Passport keys generation with force flag
**Kubernetes Service Updates:**
- Added explicit port naming: http
- Added labels and annotations
- Explicit sessionAffinity: None
**Documentation:**
- Created DEPLOYMENT.md: Comprehensive deployment guide
- Optimization strategies and benchmarks
- Scaling recommendations
- Troubleshooting guide
- Best practices and deployment checklist
