Missing tolerations for hcloud-csi-controller Deployment

[geo-schloesser]

TL;DR

The hcloud-csi-node DaemonSet in deploy/kubernetes/hcloud-csi.yml includes tolerations, but the hcloud-csi-controller Deployment doesnt.

This causes the controller to fail scheduling in clusters where control-plane nodes are tainted by default.

I am using version 2.18.3, but the problem still exists in 2.19.1

Expected behavior

kubectl get pods -n kube-system | grep csi

hcloud-csi-controller-xxxxxxxxx-xxxxx 5/5 Running 0 5m
hcloud-csi-node-xxxxx 3/3 Running 0 5m

Observed behavior

kubectl get pods -n kube-system | grep csi

hcloud-csi-controller-xxxxxxxxx-xxxxx 0/5 Pending 0 5m
hcloud-csi-node-xxxxx 3/3 Running 0 5m

Minimal working example

Add the tolerations to the hcloud-csi-controller Deployment

tolerations:
  - key: CriticalAddonsOnly
    operator: Exists
