I think this is because USER is reserved variable (it contains the name of the user that runs the container). Since in OpenShift the container is running as random UID and the PHP image does not have nss_wrapper to assign a "name" to the random UID, that variable is empty. We can add nss_wrapper to the image to populate that var.
