Unable to Deploy Helm with Latest Image

[ch8zer]

I've been trying to deploy the chart with the latest image, but haven't been able to do so successfully. What happens is the app is deployed, but I get the following (from the browser):

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

Looking at the logs:

I've been combing past posts, and the docs. I've tried enabling huge pages, and anything else that I found but I can't find the root cause of this issue.

I've also tried port-forwarding as the documentation suggests.

Is this a bug known with the latest image?

Here is my PVC:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: cloud-pvc
  namespace: lab
  labels:
    app: media
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi

My values.yaml, deployed with helm install cloud nextcloud/nextcloud --namespace lab --values values.yaml

 image:
  repository: nextcloud
  tag: stable-apache
  pullPolicy: Always

ingress:
  enabled: true
  annotations:
    kubernetes.io/ingress.class: traefik
    cert-manager.io/cluster-issuer: letsencrypt-example
    traefik.ingress.kubernetes.io/frontend-entry-points: http,https
  hosts:
    - host: cloud.example.com
      paths:
      - path: /
  tls:
  - secretName: cloud-tls
    hosts:
      - cloud.example.com

nextcloud:
  host: cloud.example.com
  username: admin

  user: cloud
  password: cloud
  database: clouddb
  existingSecret:

redis:
  enabled: true
  usePassword: false

service:
  type: ClusterIP

  accessMode: ReadWriteOnce
  size: 10Gi

Just to try and root cause the issue:

• I can still reproduce this if I use the internal database
• This config does work if I use the current, older, image tag

I'm running on k3s

I could fix the problem AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 10.42.2.113 . Set the 'ServerName' directive globally to suppress this message with the following lines at my values.yaml file:

lifecycle:
  postStartCommand: ["/bin/sh", "-c", "echo \"ServerName 172.16.4.35\" | tee -a /etc/apache2/apache2.conf"]

172.16.4.35 is the IP from metalLB Maybe this can help you.

I am experiencing this same issue, using the stable image tag. I get 500 responses but no errors or useful information in the logs.

[evatikiotis]

same for me

I suggest trying the vanilla helm installation and then add on the values.yml one by one to see which one breaks it.
