Initialize Docker Environment

You are initializing a Docker environment for a project. Follow these steps:

1. Analyze the Project

First, examine the current project to determine:

• Primary language and framework (check for package.json, requirements.txt, composer.json, go.mod, etc.)
• Required services (database, cache, queue, etc.)
• Existing Docker files (if any)

2. Consult Documentation

Read the relevant documentation files:

• skills/docker-docs/references/02-dockerfile.md for Dockerfile patterns
• skills/docker-docs/references/03-compose-fundamentals.md for compose structure
• skills/docker-docs/references/05-databases.md if database is needed
• skills/docker-docs/references/10-architecture.md for project structure

3. Generate Files

Create the following files based on project type:

Dockerfile

• Use appropriate base image for the language
• Multi-stage build for smaller images
• Non-root user for security
• Health check
• Proper COPY order for layer caching

docker-compose.yaml

• No version field (modern compose)
• Health checks for all services
• Dependencies with conditions
• Named volumes for persistence
• Proper networking (internal for databases)

.dockerignore

• Exclude node_modules, .git, .env, logs, etc.

.env.example

• Document all required environment variables
• Include sensible defaults where appropriate

4. Provide Usage Instructions

After generating files, explain:

• How to start services: docker compose up -d
• How to view logs: docker compose logs -f
• How to stop services: docker compose down
• Development workflow tips
