Docker
用容器打包并交付一切。
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.

准备好证明自己了吗？
三场考试正等着你：铜牌、银牌和金牌。
学完后你将能够
- Explain images, containers and layers, and run any service with
docker run - Write fast, cache-friendly Dockerfiles and small multi-stage images for Go and Node.js
- Run a full stack (website, API and PostgreSQL) from one
compose.yaml - Keep data, configuration and secrets safe with volumes, environment variables and secret files
- Ship images pinned by digest, then read logs, set limits and debug containers in production
- Know what Kubernetes adds, and when one Compose host is enough
学习旅程
1 第 1 单元Containers from zero
What Docker solves, images versus containers, and the commands you will type every day.
0 / 32 第 2 单元Building images
Write Dockerfiles, understand layers, and make rebuilds take seconds.
0 / 33 第 3 单元Production-ready images
Multi-stage builds, distroless and scratch, non-root users, healthchecks and scanning.
0 / 34 第 4 单元One stack, one command
Describe the website, the API and PostgreSQL in one compose.yaml, with networks and volumes.
0 / 35 第 5 单元Config, secrets and releases
Pass configuration safely, never bake secrets into images, and release images pinned by digest.
0 / 36 第 6 单元Running in production
Logs, resource limits and debugging, then what Kubernetes adds on top of containers.
