This is just warning showing because kubectl is used against OpenShift. It is just warning, no error.

MongDB error

Looks more like an issue with PV on your cluster setup? Are you using Minishift?

[surajssd]

@kadel yes I tried that on minishift which has no addons enabled!

[kadel]

can't reproduce it :-(
I've tried that on two different minishift versions and on oc cluster up and it worked for me every time

[surajssd]

LGTM, magically works for me!

[cdrage]

LGTM.

(side-bit, we need to get these README's tutorials and such on the site. but that's for later #501 )
