Ability to change SSH keys after initial cluster deploy

[janpieper]

Description

I just wanted to remove one SSH public key from the servers, but when removing the file from ssh_additional_public_keys, the terraform plan stays empty 🤷 Even adding an SSH key to that list does not have any effect to the plan.

I have the feeling this option is only used for the initial setup. What's the preferred way to manage the SSH keys after the initial setup? 🤔

Kube.tf file

module "k3s" {
  providers = { hcloud = hcloud }

  hcloud_token = local.secrets.hcloud.token

  source = "kube-hetzner/kube-hetzner/hcloud"
  version = "2.16.0"

  ssh_public_key = file(local.ssh_public_key)
  ssh_private_key = data.sops_file.ssh_private_key.raw

  ssh_additional_public_keys = [
    file("../../ssh-keys/a.pub"),
    file("../../ssh-keys/b.pub"),
    file("../../ssh-keys/c.pub"),
  ]

  # ...
}

@janpieper Indeed, the SSH keys are only setup at the initial setup. For now, you would have to do the changes manually, or deploy a new cluster.

Will turn this into a FR.
