What is Docker Compose?

A tool for defining and running multi-container Docker applications using a YAML configuration file.

Docker Compose defines multi-container applications in a docker-compose.yml file. Services, networks, and volumes are declared, and a single command (docker compose up) starts everything. This is ideal for development environments and simple deployments.

A typical configuration includes application server, database, cache (Redis), and reverse proxy containers with defined dependencies, environment variables, port mappings, and volume mounts.
