You might want to have a look at rhuss/docker-maven-plugin. It allows a seamless integration for using docker as your deployment unit:

• Use a standard Maven assembly descriptor for building images with docker:build, so you generated WAR file or your Microservice can be easily added to a Docker image.
• You can push the created image with docker:push
• With docker:start and docker:stop you can utilize your image during unit tests.

This plugin comes with a comprehensive documentation, if there are any open questions, please open an issue.

And as you might have noticed, I'm the author of this plugin ;-). And frankly, there are other docker-maven-plugins out there, which all have a slightly different focus. For a simple check, you can have a look at shootout-docker-maven which provides sample configurations for the four most active maven-docker-plugins.

The workflow then simply shifts the artifact boundary from WAR/EAR files to Docker images. mvn docker:push moves them to a Docker registry from where it is pulled during the various testing stages used in a continuous delivery pipeline.
