How do I obtain Kubernetes CA Certificate?

kubernetes x509certificate hashicorp-vault

This can be found in your kube-system (or any other) namespace by running the following on your default-token secret:

kubectl get secret <secret name> -n <namespace> -o jsonpath="{['data']['ca\.crt']}" | base64 --decode

To find the secret name run kubectl get secret -n kube-system and find the secret that starts with default-token.

This will give you something like:

-----BEGIN CERTIFICATE-----XXXXXXXXXXX....-----END CERTIFICATE-----

When you are entering this certificate, make sure to enter the BEGIN and END header and footer.
