Docker Compose

Define, configure, and run multi-container Docker applications using a single YAML file.

Docker Compose streamlines multi-container application management: it uses a declarative YAML file (typically `compose.yaml`) to specify all services, networks, and volumes for your application stack. This configuration allows developers to build, start, and stop the entire environment—for instance, a web service linked to a Redis cache and a PostgreSQL database—with one command: `docker compose up`. It’s the essential tool for efficient local development, testing, and CI/CD workflows, ensuring consistency across environments.
