For some reason, while trying to create a deployment with a configmap
mounted as a volume, I will _sometimes_ have a pod stuck in
ContainerCreating and describing the pod gives an error like so:
FirstSeen LastSeen Count From SubobjectPath Type Reason Message

Any thoughts would be appreciated, more details below.
Here's my yaml file:
apiVersion: extensions/v1beta1

replicas: 2
template:

mountPath: /etc/core-config
volumes:
- name: core-config-files-v

and output of kubectl describe configmaps core-config-files:
