DevContainer Customization Helper

This skill helps users customize their devcontainer by providing examples and guidance for common tasks.

Common Customization Patterns

Adding Packages to Dockerfile

RUN apt-get update && apt-get install -y \
    package-name \
    && apt-get clean && rm -rf /var/lib/apt/lists/*

Adding VS Code Extensions

{
  "customizations": {
    "vscode": {
      "extensions": ["publisher.extension-name"]
    }
  }
}

Adding DevContainer Features

{
  "features": {
    "ghcr.io/devcontainers/features/feature-name:version": {}
  }
}

Setting Environment Variables

{
  "remoteEnv": {
    "VAR_NAME": "value"
  }
}
