I have the same issue. It worked flawlessly before, and it seems that nothing has changed really.

I checked the Docker image, but that didn't change.

Going by this StackOverflow thread it seems to be a permission issue. Not sure how it arises though. I'll check it.

I managed to fix my issue:

Check the user-id of the pgadmin user, using:

$ cat /etc/passwd
...
pgadmin:x:5050:5050::/home/pgadmin:/bin/ash

In this case it is 5050.

Temporarily edit the deployment for getting a editable pod for chowning the /var/lib/pgadmin directory. It is best to back up the image name or command beforehand, or be able to redeploy the chart.

spec:
  template:
    spec:
      containers:
      - image: alpine:latest
        command: ["tail", "-f", "dev/null"]

Now a new pod will be deployed, which you can access using:

$ kubectl -n <namespace> exec -it <pod> sh

Then from this shell you can chown the directory to the correct user-id:

# chown -R 5050:5050 /var/lib/pgadmin

Still it would be better to have this chart resolve this issue automatically.
