 The Minishift VM contains a Docker daemon, which you can use to build the AWX images. This is generally the approach you should take, and we recommend doing so. To use this instance, run the following command to setup your environment:
- 
+
 ```bash
 # Set DOCKER environment variable to point to the Minishift VM
 $ eval $(minishift docker-env)
