5.2.3.3. HostPathProvisioner object node placement rule example

You can edit the HostPathProvisioner object directly or by using the web console.

After you deploy a virtual machine (VM) with the HPP storage class, you can remove the hostpath provisioner pod from the same node by using the node selector. However, you must first revert that change, at least for that specific node, and wait for the pod to run before trying to delete the VM.

You can configure node placement rules by specifying nodeSelector, affinity, or tolerations for the spec.workload field of the HostPathProvisioner object that you create when you install the hostpath provisioner.

Example HostPathProvisioner object with nodeSelector rule:

apiVersion: hostpathprovisioner.kubevirt.io/v1beta1
kind: HostPathProvisioner
metadata:
  name: hostpath-provisioner
spec:
  imagePullPolicy: IfNotPresent
  pathConfig:
    path: "</path/to/backing/directory>"
    useNamingPrefix: false
  workload:
    nodeSelector:
      example.io/example-workloads-key: example-workloads-value

Workloads are placed on nodes labeled example.io/example-workloads-key = example-workloads-value.
