  ## Init container Security Context
  ## Note: the chown of the data folder is done to securityContext.runAsUser
  ## and not the below volumePermissions.securityContext.runAsUser
  ## When runAsUser is set to special value "auto", init container will try to chwon the
  ## data folder to autodetermined user&group, using commands: `id -u`:`id -G | cut -d" " -f2`
  ## "auto" is especially useful for OpenShift which has scc with dynamic userids (and 0 is not allowed).
  ## You may want to use this volumePermissions.securityContext.runAsUser="auto" in combination with
  ## pod securityContext.enabled=false and shmVolume.chmod.enabled=false
  ##
  securityContext:
    runAsUser: 0
