How to use ReadWriteMany and ReadOnlyMany in JuiceFS

JuiceFS supports ReadWriteMany and ReadOnlyMany access method.

ReadWriteMany

You can use static provision or dynamic provision . We take static provision as example:

The process of creating a secret is the same as the static provision document.

Set ReadWriteMany in both PersistentVolume and PersistentVolumeClaim:

kubectl apply -f - <<EOF
---
apiVersion: v1
kind: PersistentVolume
metadata:
name: juicefs-pv
labels:
juicefs-name: ten-pb-fs
spec:
capacity:
storage: 10Pi
volumeMode: Filesystem
accessModes:
- ReadWriteMany
persistentVolumeReclaimPolicy: Retain
csi:
driver: csi.juicefs.com
volumeHandle: test-bucket
fsType: juicefs
nodePublishSecretRef:
name: juicefs-secret
namespace: default
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: juicefs-pvc
namespace: default
spec:
accessModes:
- ReadWriteMany
volumeMode: Filesystem
storageClassName: ""
resources:

volumeMounts:
- mountPath: /data

EOF

ReadOnlyMany

The process of creating a secret is the same as the static provision document.

Set ReadOnlyMany in both PersistentVolume and PersistentVolumeClaim:

kubectl apply -f - <<EOF

juicefs-name: ten-pb-fs
