User setup

kubeadm suports this https://github.com/kubernetes-sigs/cluster-api-provider-vsphere/blob/main/templates/cluster-template.yaml#L184

users:
    - name: capv
      sshAuthorizedKeys:
      - '${VSPHERE_SSH_AUTHORIZED_KEY}'
      sudo: ALL=(ALL) NOPASSWD:ALL

it would be nice to have something similar in the KThreesControlPlane

see: https://github.com/kubernetes-sigs/cluster-api/blob/b587ff982f33a7d22d32991ebbeb9ea20e3be888/bootstrap/kubeadm/api/v1beta1/kubeadmconfig_types.go#L533

Hi. I bumped into the same issue as you, so posting here a workaround.

In either preK3sCommands: or postK3sCommands: block, put something like this

- useradd -m metal3
- echo 'metal3:password' | chpasswd
- usermod -aG sudo metal3
- echo 'metal3 ALL=(ALL) NOPASSWD:ALL' | EDITOR='tee -a' visudo
- mkdir -p /home/metal3/.ssh
- chown metal3:metal3 /home/metal3/.ssh
- chmod 700 /home/metal3/.ssh
- echo '${SSH_AUTHORIZED_KEY}' > /home/metal3/.ssh/authorized_keys
- chown metal3:metal3 /home/metal3/.ssh/authorized_keys
- chmod 600 /home/metal3/.ssh/authorized_keys

I hope it helps!

Yeah, that's what I used as well but it would be nice to have a more native way of doing it like the kubeadm provider supports.
