Arquillian Cube is an Arquillian extension that can be used to manager Docker containers from Arquillian.
With this extension you can start a Docker container(s), execute Arquillian tests and after that shutdown the container(s).
The first thing you need to do is add Arquillian Cube dependency. This can be done by using Arquillian Universe approach:
Then you have three ways of defining the containers you want to start.
The first approach is using docker-compose format. You only need to define the docker-compose file required for your tests, and Arquillian Cube automatically reads it, start all containers, execute the tests and finally after that they stop and remove them.
In previous example a docker compose file version 2 is defined (it can be stored in the root of the project, or in src/{main, test}/docker or in src/{main, test}/resources and Arquillian Cube will pick it up automatically), creates the defined network and start the service defined container, executes the given test. and finally stops and removes network and container. The key point here is that this happens automatically, you don't need to do anything manual.
The second approach is using Container Object pattern. You can think of a Container Object as a mechanism to encapsulate areas (data and actions) related to a container that your test might interact with. In this case no docker-compose is required.
In this case you are using annotations to define how the container should looks like. Also since you are using java objects, you can add methods that encapsulates operations with the container itself, like in this object where the operation of checking if a file has been uploaded has been added in the container object.
Finally in your test you only need to annotate it with @Cube annotation.
Notice that you can even create the definition of the container programmatically:
In this case a Dockerfile file is created programmatically within the Container Object and used for building and starting the container.
In this case the approach is very similar to the previous one, but you are using a DSL to define the container.
You've got three ways, the first one is the standard one following docker-compose conventions, the other ones can be used for defining reusable pieces for your tests.

The third way is using Container Object DSL. This approach avoids you from creating a Container Object class and use annotations to define it. It can be created using a DSL provided for this purpose:
