Describe the issue

Dear community,

I run the helm chart version via argoCD:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: translation
  namespace: argocd
  finalizers:
    - resources-finalizer.argocd.argoproj.io
  labels:
    type: translation

spec:
  project: default

  sources:
    - repoURL: "https://helm.weblate.org"
      chart: weblate
      targetRevision: 0.4.29
      helm:
        valueFiles:
          - $values/kubernetes/translation/weblate/values.yaml

    - repoURL: "https://github.com/XXXXX/XXXXXX.git"
      targetRevision: main
      ref: values

  # Destination cluster and namespace to deploy the application
  destination:
    name: in-cluster
    namespace: translation
  # Sync policy
  syncPolicy:
    automated:
      prune: true
      selfHeal: true
      allowEmpty: false
    syncOptions:
      - Validate=true
      - CreateNamespace=true
      - PrunePropagationPolicy=foreground
      - PruneLast=true
    managedNamespaceMetadata:
      labels:
        enviroment: production
        type: translation

and use it stock vaules in the DB and redis setup

  # manually prior starting Weblate.
    userName: ''

    postgresPassword: weblate
    database: weblate
    existingSecret: ''
    secretKeys:
      userPasswordKey: postgresql-password

  db: 1
  enabled: true
  # redis.redisHost -- External redis database endpoint, to be
  # used if `redis.enabled == false`
  # @default -- `None`
  redisHost:

and noticed that the weblate pod fails to start as it tries to connect to redis service with the name translation-weblate-redis-master, however the created service of redis is named translation-redis-master.

File "/usr/local/lib/python3.11/site-packages/django_redis/client/default.py", line 670, in has_key raise ConnectionInterrupted(connection=client) from edjango_redis.exceptions.ConnectionInterrupted: Redis ConnectionError: Error -2 connecting to translation-weblate-redis-master:6379. Name or service not known.

Hi. Do you have this issue also with the most recent helm chart version? (currently 0.4.31)

[sonic-sw]

as I have overwritten the name of the service, I cannot tell you if this is still present in this version.

[Crashdoom]

This does appear to still be happening in the current version of the helm template. The redis pod is created as {helmName}-redis-master-0 and the service as {helmName}-redis-master but weblate seems to be looking for {helmName}-weblate-redis-master by default.

Edit: Same seems to happen with Postgresql as well. Changing redis.redisHost and postgresql.postgresqlHost allows you to workaround the issue in the interim.

This issue is still open, so nobody did fix that. Pull requests are welcome!
