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
