This ensures that users get a good error message early on when trying
to do something that isn't okay:
$ kubectl create -f csi-hostpath-driverinfo.yaml
The CSIDriver "hostpath.csi.k8s.io" is invalid: spec.volumeLifecycleModes: Unsupported value: "foobar": supported values: "persistent", "ephemeral"
Using a "normal" CSI driver for an inline ephemeral volume may have
unexpected and potentially harmful effects when the driver gets a
NodePublishVolume call that it isn't expecting. To prevent that mistake,
driver deployments for a driver that supports such volumes must:
- deploy a CSIDriver object for the driver
- list "ephemeral" as one of the supported modes
The default is "persistent", so existing deployments continue to work
and are automatically protected against incorrect usage.
This commit contains the API change. Generated code and manual code
which uses the new API follow.
This PR is the first step to transition CSINodeInfo and CSIDriver
CRD's to in-tree APIs. It adds them to the existing API group
“storage.k8s.io” as core storage APIs.
