General:

• none of the sidecars use CSI_ENDPOINT

external-provisioner:

• Do we need to setup -provisioner?
• Shouldn't csi-provisioner.go:96 of the provisioner use the name from returned by the endpoint?
• Got error:

$ kk logs csi-mock-driver-0 csi-external-provisioner
container_linux.go:247: starting container process caused "exec: \"/opt/csi-flex/flex-provision\": stat /opt/csi-flex/flex-provision: no such file or directory"

driver-registrar

• What is the expected yaml/spec for this?
• Error

* $ kk logs csi-mock-driver-0 csi-driver-registrar
E1207 05:25:14.707114       1 main.go:65] Node name not found. The environment variable KUBE_NODE_NAME is empty.

flexdriver

• Why does the flexdriver use "Biderectional"

csi-attacher

• All works
