Static Provisioning Subpath

Persisten volume can be provisioned as a subpath in juicefs filesystem.

Patches

Ensure you have already get familiar with static-provisioning example.

Patch the persistent volume spec with csi/volumeAttributes/subPath. The subPath must pre-exist.

apiVersion: v1
kind: PersistentVolume
metadata:
  name: juicefs-aws-us-east-1
spec:
  csi:
    volumeAttributes:
      subPath: fluentd

Apply the configurations

Build the example with kustomize and apply with kubectl

kustomize build | kubectl apply -f -

or apply with kubectl >= 1.14

kubectl apply -k .

Check JuiceFS filesystem is used

After the objects are created, verify that pod is running:

>> kubectl get pods

Also you can verify that data is written onto JuiceFS filesystem:

>> kubectl exec -ti juicefs-app -- tail -f /data/out.txt

Check that file is created under the subpath in JuiceFS console.
