I want register kubernetes-elastic-agents with gocd-server. In the doc https://github.com/gocd/kubernetes-elastic-agents/blob/master/install.md
I need kubernetes security token and cluster ca certificate. My Kubernetes is running. How do I create a security token? Where can I find the cluster ca cert?

There are two answers:
The first is that it's very weird that one would need to manually input those things since they live in a well-known location on disk of any Pod (that isn't excluded via the automountServiceAccountToken field) as described in Accessing the API from a Pod
The second is that if you really do need a statically provisioned token belonging to a ServiceAccount, then you can either retrieve an existing token from the Secret that is created by default for every ServiceAccount, or create a second Secret as described in Manually create a service account API token
The CA cert you requested is present in every Pod in the cluster at the location mentioned in the first link, as well as in the ~/.kube/config of anyone who wishes to access the cluster. kubectl config view -o yaml will show it to you.
