I'm testing the new Openshift platform based on Docker and Kubernetes.

I've created a new project from scratch, then when I try to deploy a simple MongoDB service (as well with a python app), I got the following errors in the Monitoring section in Web console:

Unable to mount volumes for pod "mongodb-1-sfg8t_rob1(e9e53040-ab59-11e6-a64c-0e3d364e19a5)": timeout expired waiting for volumes to attach/mount for pod "mongodb-1-sfg8t"/"rob1". list of unattached/unmounted volumes=[mongodb-data]
Error syncing pod, skipping: timeout expired waiting for volumes to attach/mount for pod "mongodb-1-sfg8t"/"rob1". list of unattached/unmounted volumes=[mongodb-data]

It seems a problem mounting the PVC in the container, however the PVC is correctly created and bounded:

oc get pvc

Returns:

NAME           STATUS    VOLUME         CAPACITY   ACCESSMODES   AGE
mongodb-data   Bound     pv-aws-9dged   1Gi        RWO           29m

I've deployed it with the following commands:

oc process -f openshift/templates/mongodb.json | oc create -f -

oc deploy mongodb --latest

The complete log from Web console:

The content of the template that I used is:

Is there any issue with my template ? Is it a OpenShift issue ? Where and how can I get further details about the mount problem in OpenShift logs ?
