You just need to install docker for linux (I will provide soon the instructions for windows users).
If you need to add insecure registries host on your Docker daemon to pull images from your private repository you can follow this link.
You can run local integration tests by activating docker profile during Maven build. This profile will activate Fabric8 plugin that will pull and run in containers following services from dockerhub public repository:
- mysql
- mongo
- redis
Then build will trigger integration tests against these running containers.
Finally at the end of integration-phase running containers are automatically stopped. For more details please see this post
