Alex Szakaly 0cf34953ff contrib: add control-plane toleration for open-vm-tools 
From Kubernetes v1.20.0 Release notes:
The label applied to control-plane nodes "node-role.kubernetes.io/master"
is now deprecated and will be removed in a future release after a GA
deprecation period.

Introduce a new label "node-role.kubernetes.io/control-plane" that will
be applied in parallel to "node-role.kubernetes.io/master" until the
removal of the "node-role.kubernetes.io/master" label.

open-vm-tools

This should allow end-users to gracefully reboot or shutdown Kubernetes nodes (incuding control planes) running on vSphere Hypervisor.

Furthermore, it is also mandatory to have open-vm-tools installed on your Kubernetes nodes to use vSphere Cloud Provider (i.e. determinte virtual machine's FQDN).

Remarks:

  • spec.template.spec.hostNetwork: true: correctly report node IP address; required
  • spec.template.spec.hostPID: true: send the right signal to node, instead of killing the container itself; required
  • spec.template.spec.priorityClassName: system-cluster-critical: critical to a fully functional cluster
  • spec.template.spec.securityContext.privileged: true: gain more privileges than its parent process; required
