Containerization with Docker and docker-compose creates reproducible development environments by defining your app's runtime, dependencies, and services in a Dockerfile and docker-compose.yml. This Skill generates both files plus environment variable templates, ensuring consistent builds across local and CI environments for Go, TypeScript, and Python services.

Environment variables configure service behavior without hardcoding secrets or configuration. This Skill creates .env.example templates and variable definitions alongside your Docker setup, documenting required variables and their purposes so team members can replicate your local environment accurately.

Yes. Docker-compose orchestrates multiple containers as a single reproducible environment. This Skill configures docker-compose.yml to coordinate your API, worker, batch, or CLI service with dependencies like Postgres and Redis, enabling full-stack local development and testing before deployment.

Gate 1 of the development cycle requires Docker configuration, docker-compose setup, and environment documentation. This Skill validates your existing files, creates or updates Dockerfile and docker-compose.yml as needed, and verifies builds succeed—preparing your service for consistent local and CI deployment readiness.

Yes. This Skill applies across Go, TypeScript, and Python for API, worker, batch, and CLI service types. It standardizes container builds and orchestration regardless of language, handling implementation files, new dependencies, and environment needs uniformly.

This Skill checks for existing Docker configuration files and determines whether to create new ones or update existing files based on your current state. It validates file existence, performs automated and manual verification of builds and service health, and reports changes in a structured output.
