Define and run multi-container applications with Docker

Hard-coding the API version to '1.18' with the docker-py constructor will cause the docker-py logic at https://github.com/docker/docker-py/blob/master/docker/client.py#L143-L146 to always fail, which will cause authentication issues if you're using a remote daemon using API version 1.19 - regardless of the API version of the registry. Allow the user to set the API version via an environment variable. If the variable is not present, it will still default to '1.18' like it does today.

Docker Compose
(Previously known as Fig)
Compose is a tool for defining and running multi-container applications with Docker. With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running.
Compose is great for development environments, staging servers, and CI. We don't recommend that you use it in production yet.
Using Compose is basically a three-step process.
- Define your app's environment with a
Dockerfileso it can be reproduced anywhere. - Define the services that make up your app in
docker-compose.ymlso they can be run together in an isolated environment: - Lastly, run
docker-compose upand Compose will start and run your entire app.
A docker-compose.yml looks like this:
web:
build: .
ports:
- "5000:5000"
volumes:
- .:/code
links:
- redis
redis:
image: redis
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
Installation and documentation
- Full documentation is available on Docker's website.
- If you have any questions, you can talk in real-time with other developers in the #docker-compose IRC channel on Freenode. Click here to join using IRCCloud.
