使用存储卷

使用说明

在工作流集群中支持使用OSS存储卷、NAS存储卷和CPFS2.0存储卷。

使用OSS存储卷

1. 使用以下示例代码，创建OSS存储卷。

   更多信息，请参见使用OSS静态存储卷。如果使用其他类型存储卷，请替换对应的参数。

   apiVersion: v1
   kind: Secret
   metadata:
     name: oss-secret
     namespace: default
   stringData:
     akId: <yourAccessKey ID> # akId需要替换为您的AccessKey ID。
     akSecret: <yourAccessKey Secret> # akSecret需要替换为您的AccessKey Secret。
   ---
   apiVersion: v1
   kind: PersistentVolume
   metadata:
     name: pv-oss
     labels:
       alicloud-pvname: pv-oss
   spec:
     capacity:
       storage: 5Gi
     accessModes:
       - ReadWriteMany
     persistentVolumeReclaimPolicy: Retain
     csi:
       driver: ossplugin.csi.alibabacloud.com
       volumeHandle: pv-oss   # 需要和PV名字一致。
       nodePublishSecretRef:
         name: oss-secret
         namespace: default
       volumeAttributes:
         bucket: <your bucket name> # 需要替换为您的Bucket名称。
         url: "oss-<your region id>-internal.aliyuncs.com" # 需要替换<your region id>为您OSS的地域ID，例如华北2（北京）地域为：oss-cn-beijing-internal.aliyuncs.com。
         otherOpts: "-o max_stat_cache_size=0 -o allow_other -o multipart_size=30 -o parallel_count=20"
         path: "/"  #挂载bucket根目录，也可以设置此参数挂载bucket下子目录，例如: path: "testdir/testdir1"
   ---
   apiVersion: v1
   kind: PersistentVolumeClaim
   metadata:
     name: pvc-oss
     namespace: default
   spec:
     accessModes:
       - ReadWriteMany
     resources:
       requests:
         storage: 5Gi
     selector:
       matchLabels:
         alicloud-pvname: pv-oss

2. 使用以下示例代码，创建工作流使用存储卷。

   apiVersion: argoproj.io/v1alpha1
   kind: Workflow
   metadata:
     generateName: volumes-existing-
     namespace: default
   spec:
     entrypoint: volumes-existing-example
     volumes:
     # Pass my-existing-volume as an argument to the volumes-existing-example template.
     # Same syntax as k8s Pod spec.
     - name: workdir
       persistentVolumeClaim:
         claimName: pvc-oss
   
     templates:
     - name: volumes-existing-example
       steps:
       - - name: generate
           template: whalesay
       - - name: print
           template: print-message
   
     - name: whalesay
       container:
         image: docker/whalesay:latest
         command: [sh, -c]
         args: ["echo generating message in volume; cowsay hello world | tee /mnt/vol/hello_world.txt"]
         volumeMounts:
         - name: workdir
           mountPath: /mnt/vol
   
     - name: print-message
       container:
         image: alpine:latest
         command: [sh, -c]
         args: ["echo getting message from volume; find /mnt/vol; cat /mnt/vol/hello_world.txt"]
         volumeMounts:
         - name: workdir
           mountPath: /mnt/vol

使用NAS存储卷

1. 使用以下示例代码，创建静态NAS共享卷。

   apiVersion: v1
   kind: PersistentVolume
   metadata:
     name: pv-nas
     labels:
       alicloud-pvname: pv-nas
   spec:
     capacity:
       storage: 100Gi
     accessModes:
       - ReadWriteMany
     csi:
       driver: nasplugin.csi.alibabacloud.com
       volumeHandle: pv-nas   # 必须与PV Name保持一致。
       volumeAttributes:
         server: "<your nas filesystem id>.cn-beijing.nas.aliyuncs.com"
         path: "/"
     mountOptions:
     - nolock,tcp,noresvport
     - vers=3

   kind: PersistentVolumeClaim
   apiVersion: v1
   metadata:
     name: pvc-nas
   spec:
     accessModes:
       - ReadWriteMany
     resources:
       requests:
         storage: 100Gi
     selector:

         volumeAs: subpath
         server: "<your cpfs id, e.g cpfs-****>.<regionID>.cpfs.aliyuncs.com"      # 为挂载点前面的域名。
       volumeHandle: pv-cpfs # 必须与PV Name保持一致。
     mountOptions:
     - rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport
