[powerdns-admin] persistence.data.enabled = true fails to work #1556

Closed mitchellim closed 2 years ago

mitchellim commented 2 years ago

Helm chart name

powerdns-admin

Helm chart version

1.1.1

Container name

ngoduykhanh/powerdns-admin

Container tag

v0.2.4

Description

Enabling persistence on data results in pods failing to start the first time due to an inability to write to the PVC due to permissions issues (the app runs as 100:100). The directory isn't mounted in a writable state, however:

/ $ ls -ld data
drwxr-xr-x    2 root     root             2 May  8 01:51 data

Which results in:

It might be just worth having a note in the global values.yaml under the persistence section mentioning that setting podSecurityContext.fsGroup might be necessary? In this case, it would just be:

podSecurityContext:
  fsGroup: 100
