mvn clean install have requirements not indicated

[apupier]

it seems that mvn clean install requires to have Docker and/or OpenShift installed.

It would be nice either to:

• get rid of this dependency (seems to be the best for easy use of the project)
• explain requirements in README (is it really Docker or OpenShift as requirements?)

stack when running "mvn clean install":

@apupier Is this still an issue? I think the openshift profile fixed this?
