Frequently Asked Questions

Docker Compose defines multi-container applications in YAML. It lets you configure services, networks, and volumes in one file, then start everything with 'docker-compose up'.

Version 3 is recommended for most use cases. Version 3.8 is latest for Docker Engine. Compose V2 with 'docker compose' (no hyphen) doesn't require version field.

Services on the same network can reach each other by service name. Use 'depends_on' to control startup order, though it doesn't wait for service readiness.

'image' pulls from a registry. 'build' builds from a Dockerfile. You can use both: build for development, image for production deployments.

Use volumes. Named volumes persist data between container restarts. Bind mounts map host directories to containers for development.

Compose automatically loads .env file variables. Use ${VAR} syntax in compose.yml to reference them. Great for environment-specific configs.

Use 'ports: - 8080:80' to map host:container. Only services that need external access need port mapping; internal services communicate via network.

restart: always restarts on failure or Docker restart. Use 'unless-stopped' to keep running unless manually stopped. 'on-failure' only restarts on errors.

Use 'environment:' with KEY=value pairs, or 'env_file:' to load from .env files. Variables can reference other compose variables with ${VAR}.

Yes, use docker-compose.override.yml for local overrides, or -f flag to specify multiple files. Later files override earlier ones.
