I want to connect to my kubernetes nodes (GKE) using SSH CA certificates, but in order to do so, I need to put the SSH CA public key on my fleet and add the path to the file in my sshd_config in every of my instances that gets created for kubernetes.
How should I do this? With the startup script? Or is it anything better?
Also, if I put this line on the sshd_config and I don't add any other public SSH Key, I won't have any user by default to log in.
