/**
 * OpenShift runs containers with a custom UID, overridding the UID defined in docker images.
 * This is an example of how to run docker images from DockerHub in OpenShift. It comes with no warranty.
 *
 * Define HOME for containers running in OpenShift
 * Define user.home system property for maven as it relies on /etc/passwd to infer its value
