description Docker Compose (v2) Overview

While not an orchestrator for production clusters, Docker Compose remains the gold standard for defining and running multi-container applications locally. Its v2 integration with the Docker CLI makes defining complex local stacks (database, backend, frontend) incredibly straightforward. It is indispensable for development environments and integration testing before deploying to a full cluster.

help Docker Compose (v2) FAQ

What changed from Docker Compose v1 to Docker Compose v2?

Docker Compose v2 is integrated into the Docker CLI as docker compose, while v1 used the separate docker-compose command. V2 follows the Compose Specification and is the version Docker actively expects modern projects to use.

Is Docker Compose v2 meant to replace Kubernetes?

No, Docker Compose v2 is mainly for defining and running multi-container apps on one Docker host, especially local development stacks. Kubernetes is built for cluster scheduling, scaling, and production orchestration across many nodes.

What file does Docker Compose v2 read?

Compose v2 commonly reads compose.yaml or docker-compose.yml in the project directory. A typical file defines services such as a web app, Postgres, Redis, and a worker process.

Which command starts a Compose v2 stack in the background?

The usual command is docker compose up -d. Developers then use commands like docker compose logs, docker compose ps, and docker compose down to inspect or stop the stack.
