1.3. 使用 ROSA STS 在 OADP 上备份工作负载

1. 运行以下命令，创建一个工作负载来备份：

   $ oc create namespace hello-world

   Copy to Clipboard Toggle word wrap

   $ oc new-app -n hello-world --image=docker.io/openshift/hello-openshift

   Copy to Clipboard Toggle word wrap

2. 运行以下命令来公开路由：

   $ oc expose service/hello-openshift -n hello-world

   Copy to Clipboard Toggle word wrap

3. 运行以下命令检查应用程序是否正常工作：

   $ curl `oc get route/hello-openshift -n hello-world -o jsonpath='{.spec.host}'`

   Copy to Clipboard Toggle word wrap

   输出示例

   Hello OpenShift!

   Copy to Clipboard Toggle word wrap

4. 运行以下命令来备份工作负载：

   $ cat << EOF | oc create -f -
     apiVersion: velero.io/v1
     kind: Backup
     metadata:
       name: hello-world
       namespace: openshift-adp
     spec:
       includedNamespaces:
       - hello-world
       storageLocation: ${CLUSTER_NAME}-dpa-1
       ttl: 720h0m0s
   EOF

   Copy to Clipboard Toggle word wrap

5. 等待备份完成，然后运行以下命令：

   $ watch "oc -n openshift-adp get backup hello-world -o json | jq .status"

   Copy to Clipboard Toggle word wrap

   输出示例

   {
     "completionTimestamp": "2022-09-07T22:20:44Z",
     "expiration": "2022-10-07T22:20:22Z",
     "formatVersion": "1.1.0",
     "phase": "Completed",
     "progress": {
       "itemsBackedUp": 58,
       "totalItems": 58
     },
     "startTimestamp": "2022-09-07T22:20:22Z",
     "version": 1
   }

   Copy to Clipboard Toggle word wrap

6. 运行以下命令来删除 demo 工作负载：

   $ oc delete ns hello-world

   Copy to Clipboard Toggle word wrap

7. 运行以下命令，从备份中恢复工作负载：

   $ cat << EOF | oc create -f -
     apiVersion: velero.io/v1
     kind: Restore
     metadata:
       name: hello-world
       namespace: openshift-adp
     spec:
       backupName: hello-world
   EOF

   Copy to Clipboard Toggle word wrap

8. 运行以下命令等待 Restore 完成：

   $ watch "oc -n openshift-adp get restore hello-world -o json | jq .status"

   Copy to Clipboard Toggle word wrap

   输出示例

   {
     "completionTimestamp": "2022-09-07T22:25:47Z",
     "phase": "Completed",
     "progress": {
       "itemsRestored": 38,
       "totalItems": 38
     },
     "startTimestamp": "2022-09-07T22:25:28Z",
     "warnings": 9
   }

   Copy to Clipboard Toggle word wrap

9. 运行以下命令检查工作负载是否已恢复：

   $ oc -n hello-world get pods

   Copy to Clipboard Toggle word wrap

   输出示例

   NAME                              READY   STATUS    RESTARTS   AGE
   hello-openshift-9f885f7c6-kdjpj   1/1     Running   0          90s

   Copy to Clipboard Toggle word wrap

10. 运行以下命令来检查 JSONPath：

    $ curl `oc get route/hello-openshift -n hello-world -o jsonpath='{.spec.host}'`

    Copy to Clipboard Toggle word wrap

    输出示例

    Hello OpenShift!

    Copy to Clipboard Toggle word wrap

流程

1. 运行以下命令来删除工作负载：

   $ oc delete ns hello-world

   Copy to Clipboard Toggle word wrap

2. 运行以下命令来删除数据保护应用程序 (DPA)：

   $ oc -n openshift-adp delete dpa ${CLUSTER_NAME}-dpa

   Copy to Clipboard Toggle word wrap

3. 运行以下命令来删除云存储：

   $ oc -n openshift-adp delete cloudstorage ${CLUSTER_NAME}-oadp

   Copy to Clipboard Toggle word wrap
   警告

   如果这个命令挂起，您可能需要通过运行以下命令来删除终结器：

   $ oc -n openshift-adp patch cloudstorage ${CLUSTER_NAME}-oadp -p '{"metadata":{"finalizers":null}}' --type=merge

   Copy to Clipboard Toggle word wrap

4. 如果不再需要 Operator，请运行以下命令删除它：

   $ oc -n openshift-adp delete subscription oadp-operator

   Copy to Clipboard Toggle word wrap

5. 从 Operator 中删除命名空间：

   $ oc delete ns openshift-adp

   Copy to Clipboard Toggle word wrap

6. 如果不再需要备份和恢复资源，请运行以下命令从集群中删除它们：

   $ oc delete backups.velero.io hello-world

   Copy to Clipboard Toggle word wrap

7. 要删除 AWS S3 中的备份、恢复和远程对象，请运行以下命令：

   $ velero backup delete hello-world
