This project contains the quickstarts for the fabric8 project.
If you wish to push docker images to a private or public registry you will need to add a section to your ~/.m2/settings.xml file with a login/pwd:
<servers>
<server>
<id>192.168.59.103:5000</id>
<username>jolokia</username>
<password>jolokia</password>
</server>
...
</servers>
For local containers they can be dummy login/passwords. For more details see the docker maven plugin docs
