Docker

무엇이든 컨테이너에 담아 배포하세요.

Docker packs your app and everything it needs into one standard package, an image, so it runs the same way on your laptop, in CI and on the production server. Teams use it to run websites, APIs, databases and caches as separate containers, and to pin production images by digest.

This track starts with your first docker run and takes you through fast, small Dockerfiles, multi-stage builds, Compose with networks and volumes, secrets done right, releases pinned by digest, and debugging in production. At the end you will see what Kubernetes adds on top.
