Kamal Deployment

Kamal deploys containerized applications via SSH. It builds Docker images, pushes to registries, and orchestrates zero-downtime deployments using kamal-proxy.

Quick Reference

kamal init              # Create config/deploy.yml and .kamal/secrets
kamal setup             # First-time setup (bootstrap + deploy)
kamal deploy            # Deploy new version
kamal rollback VERSION  # Revert to specific version
kamal app logs -f       # Tail application logs
kamal console           # Rails console (via alias)
