I'm trying to integrate a Kubernetes cluster into gitlab by using the "Add existing Kubernetes cluster" option. This integration is required to configure this cluster as a Runner in gitlab to execute the build.

Below details have been provided for the integration:

Kubernetes cluster name : kube_cluster
API URL : https://ipadress:port ex: https://10.8.9.0:8443
CA certificate:
CA certificate from kubernate cluster
Token: token obtained by below command
kubectl -o json get secret default-xxxxx-ght | jq -r '.data.token' | base64 -d > token.txt

but the integration fails during the Helm installation without a proper error message in git lab. How to solve this issue? Is there a way to find out what is actually failing in background?

Error message:

"Something went wrong while installing Helm Tiller
Can't start installation process"
