I find the documentation at https://github.com/jenkinsci/kubernetes-plugin quite unclear when it comes to step by step configuration of external Jenkins master.
What are the exact steps that need to be followed? I have installed the Kubernetes plugin and I have tried to supply some cluster info, but I have got lost there.
For Name I have taken the output from kubectl config view --raw, specifically the context for the given cluster and the cluster name part.
For Kubernetes URL I have set the IP address from the Server field in the same output from above.
Kubernetes server certificate key - for this part I have initially tried to follow the same pattern from above and take the value of the certificate-authority-data field, but I got an "Error testing connection https://XX.XXX.XXX.XX: java.security.cert.CertificateException: Could not parse certificate: java.io.IOException: Empty input", so I have attempted to convert that value with echo "the field value here" | base64 -d > ca.crt and use that, but it failed again and I have also got it form the UI for GKE show cluster ceritficate section, all of them give me failure on testing connection with the error from above.
I couldn't really go past this point, but I see everything being quite unclear forward, so I would appreciate a step-by-step recommendation or any guide that I am missing.
