Error updating Endpoint Slices for Service nextcloud/nextcloud

[papanito]

The nextcloud pod does not start but eventually fails. I can see this event logged:

8m40s       Warning   FailedToUpdateEndpointSlices   service/nextcloud                Error updating Endpoint Slices for Service nextcloud/nextcloud: Error deleting nextcloud-lv57c EndpointSlice for Service nextcloud/nextcloud: endpointslices.discovery.k8s.io "nextcloud-lv57c" not found

The pod itself stuck at

Initializing nextcloud 19.0.0.8 ...

Reproduction steps

Installation using the helm chart and the values.yml given below

helm upgrade nextcloud nextcloud/nextcloud --namespace nextcloud -f nextcloud.values.yml

kubectl version

Additional info

Interestingly is also, that I only see one mariadb-pod where I would expect a master and a slave according to my initial tries, using the helm chart from the previous repo

Hoi, coming into this pretty late, so please bare with me :)

Since this setup is out of date, would you mind testing with a recent version of kubernetes and the latest version of the helm chart? We've also updated our stock values.yaml here: https://github.com/nextcloud/helm/blob/master/charts/nextcloud/values.yaml

If the problem persists, please post your current values.yaml and the error you're getting now, and I'll take a look :)

I'm going to close this as stale as it's been a year with no reply. If you want to test with the latest version of the chart (which includes more recent version of mariadb too) and let us know if it's still broken in a new Issue, we'd love to help you out.

One last thing: if you do open a new issue, it would be helpful to get the output of your nextcloud pod logs, as well as what it actually says in the nextcloud level log, which you can learn more about setting here: https://github.com/nextcloud/helm/tree/main/charts/nextcloud#logging
