Arbiter crashloop on chart 8.0.0+

lzoeckle commented 7 months ago

Name and Version

bitnami/mongodb-sharded:8.0.2

What architecture are you using?

amd64

What steps will reproduce the bug?

I believe I'm running into the same bug as this previous issue, but with the sharded chart. See https://github.com/bitnami/containers/issues/63885

My values.yaml look like:

image:
  tag: 7.0.7-debian-12-r0
  pullPolicy: IfNotPresent
  debug: true
shards: 4
defaults: &defaults
  resources:
    requests:
      cpu: 20m
      memory: 256Mi
    limits:
      cpu: 500m
      memory: 512Mi
mongos:
  replicaCount: 1
  <<: *defaults
configsvr:
  replicaCount: 3
  <<: *defaults
shardsvr:
  dataNode:
    replicaCount: 2
    <<: *defaults
  arbiter:
    replicaCount: 1
    <<: *defaults

What is the expected behavior?

The arbiter should start successfully.

What do you see instead?

Crashloop with the error mkdir: cannot create directory '/bitnami/mongodb/data/db': Read-only file system

If I update the arbiter to include

containerSecurityContext:
    readOnlyRootFilesystem: false

I see mkdir: cannot create directory '/bitnami/mongodb/data/db': Permission denied instead.

Additional information

It looks like the same volumeMounts entry may be missing from the arbiter's statefulset.yaml, as in the other bug.

Adding here, I was able to get things running by including

extraVolumeMounts:
      - mountPath: /bitnami/mongodb
        name: empty-dir
        subPath: app-volume-dir

in shardsvr.arbiter.
