I want to try out the csi smb driver in a local kind cluster, but I receive an error, where the local smb server cannot be found.
I followed the tutorial at the GitHub repository for installing the smb driver, a local smb server and using it with a storageclass
But when I provision a PVC, it fails with this error message:
failed to provision volume with StorageClass "smb":
rpc error: code = Internal desc = failed to mount smb server: rpc error:
code = Internal desc = volume(smb-server.default.svc.cluster.local/share#pvc-d886cbbb-a8a3-4411-9871-e089634ec50b#) mount "//smb-server.default.svc.cluster.local/share" on "/tmp/pvc-d886cbbb-a8a3-4411-9871-e089634ec50b" failed with mount failed: exit status 1
Mounting command: mount Mounting arguments: -t cifs -o dir_mode=0777,file_mode=0777,uid=1001,gid=1001,<masked> //smb-server.default.svc.cluster.local/share /tmp/pvc-d886cbbb-a8a3-4411-9871-e089634ec50b
Output: mount error: could not resolve address for smb-server.default.svc.cluster.local: Unknown error
And there is this error message in the csi-smb-controller pod log:
E0910 13:40:48.719478 1 controller.go:957] error syncing claim "d886cbbb-a8a3-4411-9871-e089634ec50b": failed to provision volume with StorageClass "smb": rpc error: code = Internal desc = failed to mount smb server: rpc error: code = Internal desc = volume(smb-server.default.svc.cluster.local/share#pvc-d886cbbb-a8a3-4411-9871-e089634ec50b#) mount "//smb-server.default.svc.cluster.local/share" on "/tmp/pvc-d886cbbb-a8a3-4411-9871-e089634ec50b" failed with mount failed: exit status 1

But the used service is present in my kind cluster:
kubectl get service -A simon@edora
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 20m
default smb-server ClusterIP 10.96.24.87 <none> 445/TCP 19m
kube-system kube-dns ClusterIP 10.96.0.10 <none> 53/UDP,53/TCP,9153/TCP 20m
When I try to access the share with smbclient in an ubuntu pod, it connects, but I get a NT_STATUS_ACCESS_DENIED error when trying to list the root directory:
# smbclient -U USERNAME //smb-server.default.svc.cluster.local/share
Password for [WORKGROUP\USERNAME]:
Try "help" to get a list of possible commands.
smb: \> ls
NT_STATUS_ACCESS_DENIED listing \*
