Dockerfile best practices, CI testing patterns, and Docker Compose orchestration.\n\n## Features\n\n- **Dockerfile Best Practices** - Multi-stage builds, layer optimization, security\n- **CI Testing Patterns** - Test Docker images reliably in CI pipelines\n- **Docker Compose** - Service orchestration, health checks, networking\n- **Docker Bake** - Multi-platform builds with BuildKit\n- **Security** - Vulnerability scanning, non-root users, secret management\n\n## Automatic Triggers\n\nThis skill activates automatically when working with:\n\n| File Pattern | Description |\n|--------------|-------------|\n| `Dockerfile`, `Dockerfile.*`, `*.dockerfile` | Container image definitions |\n| `docker-compose.yml`, `compose.yml` | Multi-container orchestration |\n| `docker-bake.hcl` | BuildKit bake configurations |\n| `.dockerignore` | Build context optimization |\n\n## Installation\n\n### Marketplace (Recommended)\n\nAdd the [Netresearch marketplace](https://github.com/netresearch/claude-code-marketplace) once, then browse and install skills:\n\n```bash\n# Claude Code\n/plugin marketplace add netresearch/claude-code-marketplace\n```\n\n### npx ([skills.sh](https://skills.sh))\n\nInstall with any [Agent Skills](https://agentskills.io)-compatible agent:\n\n```bash\nnpx skills add https://github.com/netresearch/docker-development-skill --skill docker-development\n```\n\n### Download Release\n\nDownload the [latest release](https://github.com/netresearch/docker-development-skill/releases/latest) and extract to your agent's skills directory.\n\n### Git Clone\n\n```bash\ngit clone https://github.com/netresearch/docker-development-skill.git\n```\n\n### Composer (PHP Projects)\n\n```bash\ncomposer require netresearch/docker-development-skill\n```\n\nRequires [netresearch/composer-agent-skill-plugin](https://github.com/netresearch/composer-agent-skill-plugin).\n## Usage\n\nThe skill activates automatically when working on:\n- Dockerfile development\n- Docker Compose configurations\n- Docker Bake multi-platform builds\n- CI/CD pipelines for container images\n- Container troubleshooting\n\n### Example Prompts\n\n- \"Create a multi-stage Dockerfile for a Node.js app\"\n- \"Set up GitHub Actions to build and push Docker images\"\n- \"Why is my nginx config test failing in CI?\"\n- \"Add health checks to my docker-compose.yml\"\n- \"Create a docker-bake.hcl for multi-platform builds\"\n\n## Key Patterns\n\n### Testing Images with Entrypoints\n\n```bash\n# Bypass entrypoint for direct testing\ndocker run --rm --entrypoint php myimage -v\n```\n\n### Testing nginx Configs in Isolation\n\n```bash\n# Mock upstream DNS\ndocker run --rm --add-host backend:127.0.0.1 nginx-image nginx -t\n```\n\n### Compose Validation in CI\n\n```bash\n# Create .env before validation\ncp .env.example .env\nsed -i 's/PLACEHOLDER/test_value/g' .env\ndocker compose config \u003e /dev/null\n```\n\n## References\n\nExtended documentation in `skills/docker-development/references/`:\n\n- `ci-testing.md` -
