azure - 如何使用有状态集 kubernetes 将 cassandra 数据位置挂载到 azure 文件共享

Question

我正在使用 Statefull set Kubernetes 在 Azure 上设置 3 节点 Cassandra 集群，但无法在 azure 文件共享中挂载数据位置。

我可以使用默认的 kubenetes 存储，但不能使用 Azurefile 共享选项。

我尝试了下面给出的以下步骤，在 volumeClaimTemplates 中发现了困难

apiVersion: "apps/v1"
kind: StatefulSet
metadata:
  name: cassandra
  labels:
    app: cassandra
spec:
  serviceName: cassandra
  replicas: 3
  selector:
    matchLabels:
      app: cassandra

                fieldRef:

          volumeMounts:
          - mountPath: /var/lib/cassandra/data
            name: pv002
  volumeClaimTemplates:
  - metadata:
      name: pv002
    spec:
      storageClassName: default
      accessModes:

  accessModes:

  azureFile:
    secretName: storage-secret

    readOnly: false

我应该能够将每个 cassandra 节点的数据文件夹挂载到 azure 文件共享中。

对于在 statefulset 中使用 azure 文件，我认为您可以遵循以下示例：https ://github.com/andyzhangx/demo/blob/master/linux/azurefile/attach-stress-test/statefulset-azurefile1-2files.yaml
