Docker Compose
🤩 **
** Compose V2 is on its way! We are currently polishing the next generation of Docker Compose, to be released soon...
- Read more on RC1 announcement.
- Check the v2 branch on this repo.
We are working towards providing an easy way to install Compose V2 on Linux. Once this is available, Compose V2 will be marked as generally available, our current target for this is the end of October.
⏳
V1 vs V2 transition "Generally Available" will mean:
- New features and bug fixes will only be considered in the V2 codebase
- Users on Mac/Windows will be defaulted into Docker Compose V2, but can still opt out through the UI and the CLI. This means when running
docker-compose
you will actually be runningdocker compose
- Our current goal is for users on Linux to receive Compose v2 with the latest version of the docker CLI, but is pending some technical discussion. Users will be able to use compose switch to enable redirection of
docker-compose
todocker compose
- Docker Compose V1 will continue to be maintained regarding security issues
- v2 branch will become the default one at that time
docker-compose
to docker compose
. We want to make it as easy as possible to switch and not break any ones scripts. We will follow up with a blog post in the next few months with more information of an exact timeline of V1 being marked as deprecated and end of support for security issues. We’d love to hear your feedback! You can provide it here.
About
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
.
Compose files can be used to deploy applications locally, or to the cloud on Amazon ECS or Microsoft ACI using the Docker CLI. You can read more about how to do this:
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.
Using pip
If your platform is not supported, you can download Docker Compose using pip
:
pip install docker-compose
Note: Docker Compose requires Python 3.6 or later.
Quick Start
Using Docker Compose is basically 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
You can find examples of Compose applications in our Awesome Compose repository.
For more information about the Compose format, see the Compose file reference.
