Install and configuring KKP on on-premises

[udupicloud]

Hi everyone,

I am new to KKP and have basic knowledge of deployments in K8s for a year.
Please help me.

When I run to setup the KKP on on-premises. I get below given error. How do I fix it.

ceph@node3:~$ ./kubermatic-installer deploy --config examples/kubermatic.example.yaml --helm-values examples/values.example.yaml --storageclass azure --kubeconfig ~/.kube/config

Currently I am deploying on 2 nodes, once things goes good will add additional and also move to cloud.

Thanks and Regards,
Mark.

Can you post your KubermaticConfiguration (please remove credentials and secrets first)?
