Docker Compose v2

Docker Compose is a tool for running multi-container applications on Docker defined using the Compose file format. A Compose file is used to define how the one or more containers that make up your application are configured. Once you have a Compose file, you can create and start your application with a single command: docker-compose up.

Where to get Docker Compose

Windows and macOS

Docker Compose is included in Docker Desktop for Windows and macOS.

Linux

You can download Docker Compose binaries from the release page on this repository.

Copy the relevant binary for your OS under $HOME/.docker/cli-plugins/docker-compose (might require to make the downloaded file executable with chmod +x)

Quick Start

Using Docker 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 Compose file looks like this:

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