Pydio Cells - Helm Chart

I really like the idea of pydio cells and would like to deploy it on my k8s cluster. However the helm chart which I found at Pydio | Kubernetes Quick install seems unusable to me. Because I have found no way to use my own clusterissuer for the creation of TLS certificates. Furthermore, when I have enabled the ingress in the helm chart, I got an error that there is already an ingress class with the name nginx.

So is it possible to somehow not deploy a clusterissuer and a nginx controller, because I think most k8s users will already have those in their setup.

The error is the following when installing it with the following values.


Error: INSTALLATION FAILED: Unable to continue with install: IngressClass "nginx" in namespace "" exists and cannot be imported into the current release: invalid ownership metadata; annotation validation error: key "" must equal "cells": current value is "ingress-nginx"; annotation validation error: key "" must equal "pydio": current value is "ingress-nginx"

Additionally, some vault webhooks are created which prevent from replicasets to work unless they are deleted when pydio cells is uninstalled using helm
