Is it safe to commit `certificate-authority-data`?

1

Dear All,
I am trying to understand what the field certificate-authority-data is for in the kubeconifg.yml file.

Following the k8s hosting guide, after I run the command:

fly ext k8s create

I am left with a kubeconfig.yml file, which looked like this:

apiVersion: v1
clusters:
  - name: fks-merman-rime-polished-star-804
    cluster:
      certificate-authority-data:<long_private_key_looking_value>
      server: https://fks-merman-rime-polished-star-804.flycast:6443
      extensions:
        - name: client.authentication.k8s.io/exec
          extension:
            org: merman-rime
contexts:
- context:
    cluster: fks-merman-rime-polished-star-804
    user: default
  name: default
current-context: default
kind: Config
preferences: {}
users:
  - name: default
    user:
      exec:
        command: fly
        args:
          - ext
          - k8s
          - kubectl-token
        apiVersion: client.authentication.k8s.io/v1
        provideClusterInfo: true
        interactiveMode: Never

Am I supposed to commit this file to source control? What does certificate-authority-data field do?
