# Docker Operations Comprehensive Docker patterns for building, running, and composing containerized applications. ## Dockerfile Best Practices | Practice | Do | Don't | |----------|------|-------| | Base image | `FROM node:20-slim` | `FROM node:latest` | | Layer caching | Copy dependency files first, then source | `COPY . .` before `RUN install` | | Package install | `apt-get update && apt-get install -y ... && rm -rf /var/lib/apt/lists/*` | Separate `RUN` for update and install | | User | `USER nonroot` (create if needed) | Run as root in production | | Multi-stage | Separate build and runtime stages | Ship compiler toolchains | | Secrets | `--mount=type=secret` (BuildKit) | `COPY .env .` or `ARG PASSWORD` | | ENTRYPOINT vs CMD | `ENTRYPOINT` for fixed binary, `CMD` for defaults | Relying on shell form for signal handling | | WORKDIR | `WORKDIR /app` | `RUN cd /app && ...` | | .dockerignore | Include `.git`, `node_modules`, `__pycache__` | No .dockerignore at all | | Labels | `LABEL org.opencontainers.image.*` | No metadata | ## Multi-Stage Build Decision Tree Choose your runtime base image by language: ``` Go ──────────── CGO disabled? ──── Yes ──► scratch or distroless/static No ───► distroless/base or alpine Rust ─────────── Static musl? ──── Yes ──► scratch or distroless/static No ───► distroless/cc or debian-slim Node.js ──────── Need native? ──── Yes ──► node:20-slim ...

docker-patterns

Docker and container best practices for writing efficient, secure, production-ready images. Use this skill whenever you are writing or editing a Dockerfile or docker-compose.yml, configuring devcontainers, debugging a failing container build, shrinking image size, speeding up build times, or hardening a container against security vulnerabilities. If Docker is in scope, load this skill first.

dockerfile-best-practices

Write or review a Dockerfile and compose setup for a production service: multi-stage builds that ship only the runtime, pinned base images, layer order for cache hits, non-root user, minimal image size, correct signal handling and health checks, secrets kept out of layers, and language-specific patterns for Node, Python, Go, and Java. Use when containerising a service, when images are large or slow to build, when a container ignores SIGTERM, or when a security scan flags the image.
