Docker compose Commands

Docker Compose is a tool used for defining and running multi-container Docker applications. It uses YAML files to configure the services, networks, and volumes for your application’s containers. Here are some commonly used Docker Compose commands:

👉 docker-compose up: This command creates and starts all the containers defined in your docker-compose.yml file. If the containers don't exist, they are created.

$ docker-compose up

If you want the containers to run in detached mode (in the background), you can use the -d flag:

$ docker-compose up -d

👉 docker-compose down: This command stops and removes all the containers defined in your docker-compose.yml file.

$ docker-compose down

👉 docker-compose ps: This command shows the status of containers managed by Docker Compose.

$ docker compose ps

example-foo-1   alpine    "/entrypoint.…"   foo        4 seconds ago   Up 2 seconds    0.0.0.0:8080->80/tcp

By default, only running containers are shown. --all flag can be used to include stopped containers.

$ docker compose ps --all
