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 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
.
About update and backward compatibility
Docker Compose V2 is a major version bump release of Docker Compose. It has been completely rewritten from scratch in Golang (V1 was in Python). The installation instructions for Compose V2 differ from V1. V2 is not a standalone binary anymore, and installation scripts will have to be adjusted. Some commands are different.
For a smooth transition from legacy docker-compose 1.xx, please consider installing compose-switch to translate docker-compose ...
commands into Compose V2's docker compose ....
. Also check V2's --compatibility
flag.
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.
Rename the relevant binary for your OS to docker-compose
and copy it to $HOME/.docker/cli-plugins
Or copy it into one of these folders to install it system-wide:
/usr/local/lib/docker/cli-plugins
OR/usr/local/libexec/docker/cli-plugins
/usr/lib/docker/cli-plugins
OR/usr/libexec/docker/cli-plugins
(might require making the downloaded file executable with chmod +x
)
Quick Start
Using Docker Compose is a three-step process:
- Define your app's environment with a
Dockerfile
so it can be reproduced anywhere. - Define the services that make up your app in
docker-compose.yml
so they can be run together in an isolated environment. - 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
