Docker Compose
==============
![Docker Compose](logo.png?raw=true "Docker Compose Logo")

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 [the list of features](docs/index.md#features).

Compose is great for development, testing, and staging environments, as well as
CI workflows. You can learn more about each case in
[Common Use Cases](docs/index.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:

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

For more information about the Compose file, see the
[Compose file reference](docs/compose-file.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
