Simplified monorepo with docker compose for local development, CI and production

Docker Compose is often treated as a “local-only” tool, while CI pipelines reimplement the same logic with custom scripts and duplicated image definitions. That duplication causes drift, surprises, and unnecessary complexity.

Using multi-stage Dockerfiles combined with build targets selected via environment variables, Docker Compose can become the single source of truth for:

local development
production-like local testing
CI build
CI push

No separate compose files. No duplicated CI job definitions per image.
