Important
📣 Docker Compose is now included as part of the https://hub.docker.com/_/docker 🎉

This image contains Compose v1, which has reached end of life (EOL) and is no longer supported. This image’s tags are frozen and are not updated.

If you want to use Compose directly from a container you can use the https://hub.docker.com/_/docker:

>docker run --rm -it docker compose version`   
Docker Compose version v2.20.2`  

If you want to embed Compose inside your own image, you can use the https://hub.docker.com/repository/docker/docker/compose-bin/general to copy the Compose binary into your image:

# syntax=docker/dockerfile:1
FROM my-image
COPY --from=docker/compose-bin:v2.20.2 /docker-compose /usr/bin/compose
RUN compose version

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application's services. Then, using a single command, you create and start all the services from your configuration. To learn more about all the features of Compose see https://github.com/docker/docker.github.io/blob/master/compose/overview.md#features.

Compose is great for development, testing, and staging environments, as well as CI workflows. You can learn more about each case in https://github.com/docker/docker.github.io/blob/master/compose/overview.md#common-use-cases.

Using Compose is basically a three-step process.

1. Define your app's environment with a Dockerfile so it can be reproduced anywhere.
2. Define the services that make up your app in docker-compose.yml so they can be run together in an isolated environment.
3. Lastly, run docker-compose up and Compose will start and run your entire app.

A docker-compose.yml looks like this:

version: '2'

services:
  web:
    build: .
    ports:
     - "5000:5000"
    volumes:
     - .:/code
  redis:
    image: redis

For more information about the Compose file, see the https://github.com/docker/docker.github.io/blob/master/compose/compose-file/compose-versioning.md

Compose has commands for managing the whole lifecycle of your application:

• Start, stop and rebuild services
• View the status of running services
• Stream the log output of running services
• Run a one-off command on a service
