I Built a Production Web App in One Weekend (Docker GRADUATION)

📄 Zusammenfassung

Now it's time to snap all those pieces together into one real, multi-service application, packaged and shipped to a real server with a real URL. Here's what you're building: four containers, one Compose file, one server, one URL. Notice the details that matter: the API image is pinned to a real semver tag, never latest, secrets live in a .env file outside of git, every service has a restart policy, the API has a real healthcheck, and pgdata is the one named volume that survives a redeploy. Twelve real skills — running containers, persisting data with volumes, writing production Dockerfiles, composing multi-service stacks, pushing to Hub, GHCR or ECR, multi-stage builds with a non-root USER, triaging with logs and exec, deploying over SSH to a real server. Before you go, here's the whole series compressed onto one page — eighteen commands that cover ninety percent of what you'll ever do with Docker.
