The pods started by mysql operator run as root

The pods started by mysql operator which form the local mysql cluster, run as root. To allow the pods to run in my environment which has PSP enabled, I had to give following PSP config for it to work.

---
apiVersion: policy/v1beta1
kind: PodSecurityPolicy
metadata:
  name: mysql-cluster
  annotations:
    seccomp.security.alpha.kubernetes.io/allowedProfileNames: 'docker/default'
    seccomp.security.alpha.kubernetes.io/defaultProfileName:  'docker/default'
spec:
  privileged: false
  # Required to prevent escalations to root.
  allowPrivilegeEscalation: false
  requiredDropCapabilities:

  - MKNOD

  - 'configMap'
  - 'emptyDir'
  - 'projected'
  - 'secret'
  - 'downwardAPI'
  - 'persistentVolumeClaim'
  - 'hostPath'
  hostNetwork: false
  hostIPC: false
  hostPID: false
  runAsUser:
    rule: 'RunAsAny'
  seLinux:
    rule: 'RunAsAny'
  supplementalGroups:
    rule: 'MustRunAs'
    ranges:
    # Forbid adding the root group.
    - min: 1
      max: 65535
  fsGroup:
    rule: 'MustRunAs'
    ranges:
    # Forbid adding the root group.
    - min: 1
      max: 65535
  readOnlyRootFilesystem: false

If you see specifically I had to allow any user on the pod:

  runAsUser:
    rule: 'RunAsAny'

when it was following the pod would go in crashloopbackoff:

  runAsUser:
    # Require the container to run without root privileges.
    rule: 'MustRunAs'
    ranges:
    - min: 1
      max: 99999

Is there a way to run the services in all the containers to run as non-root?

@AMecea this is still open presslabs/docker-orchestrator#5 can you review that?
