multi-stage-dockerfile — Skills

What it does

Use a builder stage for compilation, dependency installation, and other build-time operations

Use a separate runtime stage that only includes what's needed to run the application

Copy only the necessary artifacts from the builder stage to the runtime stage

Use meaningful stage names with the AS keyword (e.g., FROM node:18 AS builder)

Place stages in logical order: dependencies → build → test → runtime

Start with official, minimal base images when possible

Specify exact version tags to ensure reproducible builds (e.g., python:3.11-slim not just python)

Build optimized, secure multi-stage Dockerfiles for any language or framework.
