Overview
Dev Containers define reproducible development environments in Docker. Open a repo in VS Code or GitHub Codespaces and get the exact same environment — tools, extensions, settings pre-installed.
Instructions
Step 1: Basic Config
json
// .devcontainer/devcontainer.json — Dev environment definition
{
"name": "My Project",
"image": "mcr.microsoft.com/devcontainers/typescript-node:20",
"features": {
"ghcr.io/devcontainers/features/docker-in-docker:2": {},
"ghcr.io/devcontainers/features/github-cli:1": {}
},
"forwardPorts": [3000, 5432],

"esbenp.prettier-vscode"
],
"settings": { "editor.formatOnSave": true }
}
}
}
Step 2: With Database
yaml
# .devcontainer/docker-compose.yml
services:
app:
image: mcr.microsoft.com/devcontainers/typescript-node:20
volumes: [../:/workspace:cached]
command: sleep infinity
db:
image: postgres:16
environment:
POSTGRES_PASSWORD: postgres
POSTGRES_DB: myapp
volumes: [pgdata:/var/lib/postgresql/data]
volumes:

Guidelines
- New developer: clone → open in VS Code → "Reopen in Container" → ready.
- Features marketplace adds tools without custom Dockerfiles.
- Works with GitHub Codespaces — same config, cloud-hosted.
