Docker Compose deploys multi-container websites with a single configuration file, making setups reproducible across development and production servers.

A typical Compose deployment includes a web service, a database service if needed, shared volumes for persistent data, and a network connecting them.

Writing the Compose file carefully, with pinned image versions and environment variables for secrets, prevents deployment surprises.

Volumes preserve important data such as databases and uploads when containers are recreated during updates.

Updates with Compose are straightforward: pull new images, recreate containers, and verify the site, with a rollback plan if something fails.
