部署MongoDB Ops ManagerMongoDB Ops Manager

使用 Kubernetes Operator 配置文件系统备份存储

Kubernetes 操作符支持存储文件系统快照。

先决条件

To configure file system snapshot storage, your Kubernetes Operator deployment must have a storage class configured with the ReadWriteMany method.

步骤

要配置文件系统快照存储，请执行以下操作：

创建 PersistentVolumeClaim 对象。

Create a PersistentVolumeClaim object, and allocate storage as needed. Set accessModes to ReadWriteMany:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: snapshot-store-ops-manager
spec:
  storageClassName: managed-nfs-storage #SC that supports(RWX)
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10G
    ...

创建并应用 Ops Manager 自定义资源定义，指定您的 PersistentVolumeClaim。

Create an Ops Manager CustomResourceDefinition that specifies your PersistentVolumeClaim object and the spec.backup.fileSystemStores field, which is the name of your file system snapshot store.

The following example creates a CustomResourceDefinition file named ops-manager-fs.yaml, for the MongoDB oplog store with a kube-user.

apiVersion: mongodb.com/v1
  kind: MongoDBOpsManager
  metadata:
    name: ops-manager
  spec:
    replicas: 1
    version: 8.0.0
    adminCredentials: ops-manager-admin-secret
    statefulSet:
      spec:
        template:
          spec:
            volumes:
              - name: snapshot-store
                persistentVolumeClaim:
                  claimName: snapshot-store-ops-manager
            containers:
              - name: mongodb-ops-manager
                volumeMounts:
                  - name: snapshot-store
                    mountPath: /snapshot_store
    backup:
      enabled: true
      fileSystemStores:
        - name: filesystem1
      assignmentLabels: ["test1", "test2"]
      opLogStores:
        assignmentLabels: ["test1", "test2"]
        - name: oplog1
          mongodbResourceRef:
            name: oplog-db
          # mongodbUserRef:
          #   name: kube-user
      statefulSet:
        spec:
          template:
            spec:
              volumes:
                - name: snapshot-store
                  persistentVolumeClaim:
                    claimName: snapshot-store-ops-manager
              containers:
                - name: mongodb-backup-daemon
                  volumeMounts:
                    - name: snapshot-store
                      mountPath: /snapshot_store
    applicationDatabase:
      members: 3
      version: 8.0.0

将更改应用于 Ops Manager 部署。

对您的 Ops Manager 资源定义的文件名调用以下kubectl命令：

kubectl apply -f <opsmgr-resource>.yaml

配置 oplog 存储。

等待您的 Ops Manager 对象将其状态报告为，然后按照“ 部署Running Ops Manager 资源 ”过程的“ 配置备份设置 ”步骤中的描述配置您的 oplog 存储。

在 Ops Manager 中创建文件系统快照存储。

登录到您的 Ops Manager 实例并导航到： Admin Backup Snapshot Store Create New File System Store 。

Set the name to the value you set for backup.fileSystemStores in your CustomResourceDefinition. Set the other values as appropriate, then click Create.

创建新的文件系统存储后，Ops Manager 对象将报告Pending的BACKUP状态。
