[JoeyC-Dev]

What type of PR is this?
/kind documentation

What this PR does / why we need it:
Customer may use bool instead of string in yaml configuration and will cause the error below:

Error from server (BadRequest): error when creating "test.yaml": PersistentVolume in version "v1" cannot be handled as a PersistentVolume: json: cannot unmarshal bool into Go struct field CSIPersistentVolumeSource.spec.csi.volumeAttributes of type string  

Add a reminder will help.

This works:

  csi:
    volumeAttributes:
      mountWithWorkloadIdentityToken: 'true'

This doesn't work:

  csi:
    volumeAttributes:
      mountWithWorkloadIdentityToken: true

Hi @JoeyC-Dev. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
