Rainbond docking with external storage configuration

If no storage is configured when the cluster is initialized, NFS is installed as storage by default.

This article introduces three ways to connect to external：

  • Docking with Alibaba Cloud NAS
  • Docking GlusterFS
  • Docking other StorageClass

Docking with Alibaba Cloud NAS​

  • First, you need to create a NAS in Alibaba Cloud, you can refer to Alibaba CloudFile Storage NASdocument

Modify the following parameters during cluster initialization, refer toCluster initialization configuration.

Obtain the server address on the Alibaba Cloud NAS page and replace the following NAS_SERVER_ADDR.

apiVersion: rainbond.io/v1alpha1
kind: RainbondCluster
metadata:
  name: rainbondcluster
  namespace: rbd-system
spec:
  rainbondVolumeSpecRWX:
    csiPlugin: 
      aliyunNas: {}
    storageClassParameters:
      mountOptions: 
      - "nolock,tcp ,noresvport"
      - "vers=4"
      - "minorversion=0"
      - "rsize=1048576"
      - "wsize=1048576"
      - "timeo=600"
      - "retrans=2"
      - "hard"
      parameters: 
        volumeAs: subpath
        archiveOnDelete: "true"
        server: <NAS_SERVER_ADDR>

Docking with GlusterFS​

Refer to theGluster Distributed Storagedocument for installation.

After the installation is complete, modify the following parameters during cluster initialization, refer toCluster initialization configuration.

Get storageClassName by command kubectl get sc Replace GFS_CLASS_NAME.

If there are mount parameters, please specify them in storageClassParameters.

apiVersion: rainbond.io/v1alpha1
kind: RainbondCluster
metadata:
  name: rainbondcluster
  namespace: rbd-system
spec:
  rainbondVolumeSpecRWX:
    storageClassName: <GFS_CLASS_NAME>
    storageClassParameters: {}
    # mountOptions: 
    # - "vers=4 "

Docking with other StorageClass​

To connect to other StorageClasses, Rainbond's requirements are as follows：

  • The PV created by StorageClass must be spec.nfs spec.glusterfs, the following is example：
spec:
  accessModes:
  - ReadWriteMany
  capacity:
    storage: 1Gi
  # nfs or glusterfs
  nfs:
    path: /export/pvc-94cd9160-adba-4950-a7b0-ed6779ec13fb
    server: 10.43.92.23
  persistentVolumeReclaimPolicy: Retain
  storageClassName: rainbondvolumerwx
  volumeMode: Filesystem

If the above content confirms that there is no problem, modify the following parameters during cluster initialization, refer tocluster initialization configuration.

Get storageClassName by command kubectl get sc Replace CLASS_NAME.

If there are mount parameters, please specify them in storageClassParameters.

apiVersion: rainbond.io/v1alpha1
kind: RainbondCluster
metadata:
  name: rainbondcluster
  namespace: rbd-system
spec:
  rainbondVolumeSpecRWX:
    storageClassName: <CLASS_NAME>
    storageClassParameters: {}
    # mountOptions: 
    # - "vers=4 "
