Original GitHub issue: https://github.com/open-webui/helm-charts/issues/210

The clusterDomain setting in the Helm chart is not correctly applied to the Redis sub-chart. When specifying a custom cluster domain, such as:

clusterDomain: cluster.test.local
redis-cluster:
  enabled: true

The expected domain should be used for the Redis service discovery. However, the resulting configuration still defaults to cluster.local, as seen in the generated environment variable:

- name: REDIS_MASTER_HOST
  value: open-webui-redis-master-0.open-webui-redis-headless.open-webui.svc.cluster.local

Workaround:

clusterDomain: cluster.test.local
redis-cluster:
  enabled: true
  clusterDomain: cluster.test.local

Redis sub-chart has been removed due to Bitnami chart changes, this is no longer relevant.
