* change default `/opt/local-path-provisioner` path to `/var/local-path-provisioner` * change default `/opt/local-path-provisioner` path to `/var/local-path-provisioner`
* make `local-path` storage class the default storage class (optional) * make `local-path` storage class the default storage class (optional)
* label the `local-path-storage` namespace as privileged to allow privileged pods to be scheduled there * label the `local-path-storage` namespace as privileged to allow privileged pods to be scheduled there
As for the `hostPath` mounts (see above), this will require the `kubelet` to bind mount the node's folder you chose (eg: `/var/local-path-provisioner`).
Otherwise, you'll have erratic behavior, especially when using the `subPath` statement in a `volumeMount`, which may lead to data loss and/or data never freed after PV deletion.
```yaml
machine:
kubelet:
extraMounts:
- destination: /var/local-path-provisioner
type: bind
source: /var/local-path-provisioner
options:
- bind
- rshared
- rw
```
