missing prefix on k8s 1.24

[cschmatzler]

Hi! First of all:

Client Version: v1.24.2
Kustomize Version: v4.5.4
Server Version: v1.24.2

As described in #80, the missing prefix hcloud:// is caused by the missing --cloud-provider=external flag. As the README also states, though, this flag has been removed in k8s 1.24. Unfortunately, I am getting this same error on the newer version of Kubernetes. Since the flag has been removed, I am unsure on how to proceed here getting the CCM set up.

E0711 18:28:16.043416       1 node_controller.go:237] hcloud/instances.InstanceExistsByProviderID: missing prefix hcloud://

The --cloud-provider=external flag has not been removed for kubelet, it is only deprecated (see https://github.com/kubernetes/kubernetes/pull/110066 for some background).

I have the same issue. I can confirm that --cloud-provider=external flag has been added at kubeadm init stage.

Any ideas anyone?

Cluster version is 1.24.3.

OK, I think the reason for this is because the --cloud-provider=external flag is being set by the systemd drop-in as per the instructions, however is being unset by the following file: /etc/sysconfig/kubelet.

I've done the following:

yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes

systemctl enable --now kubelet
systemctl enable --now containerd
systemctl enable --now docker

cat > /etc/sysconfig/kubelet <<EOF
KUBELET_EXTRA_ARGS=--cloud-provider=external
EOF

systemctl restart kubelet

Don't forget to do this on both the leaders and all workers otherwise it will cause errors.

My issues are now gone.
