Hi Team,
I wanted to understand how the ca certificate in the kubernetes cluster is created / generated when a new cluster is brought up ?. Is there any document or guide which explains this ca certificate generation for a new kubernetes cluster.
Also whenever we create a service account, I see a secret is created which has below fields under the data.
ca.crt, namespace, token
Can someone explain how the data in ca.crt field is populated by kubernetes ?
