kubernetes - GKE 集群的 velero 备份失败

Question

我正在尝试使用 velero 创建 GKE Cluster 的备份。我在 GKE 集群 上成功安装，如下所示

   $ kubectl get deployment/velero --namespace velero
   NAME     READY   UP-TO-DATE   AVAILABLE   AGE
   velero   1/1     1            1           43h 

   $ kubectl get pods --namespace velero
   NAME                      READY   STATUS    RESTARTS    AGE
   velero-847c69f497-hwv6l   1/1     Running     0          43h  

我执行了以下命令来启动备份

  $ velero backup create cluster1-backup --include-namespaces default --snapshot-volumes
  Backup request "cluster1-backup" submitted successfully.
  Run `velero backup describe cluster1-backup` or `velero backup logs cluster1-backup` for more details.

看起来备份过程失败

  $ velero backup describe cluster1-backup
   Name:         cluster1-backup
   Namespace:    velero
   Labels:       velero.io/storage-location=default
   Annotations:  velero.io/source-cluster-k8s-gitversion=v1.15.12-gke.20
   velero.io/source-cluster-k8s-major-version=1
   velero.io/source-cluster-k8s-minor-version=15+

   Phase:  Failed (run `velero backup logs cluster1-backup` for more information)

日志显示以下内容

$ velero backup logs cluster1-backup
An error occurred: timed out waiting for download URL

我在 SharedVPC 上使用公共(public) GKE 集群，且仅启用了主授权网络 35.235.240.0/20。有解决问题的建议吗？

问题现已解决

在日志中看到以下错误

 kubectl logs deployment/velero -n velero
 

time="2020-10-05T13:41:19Z"level=error msg="获取此位置的备份存储时出错"backupLocation=defaultcontroller=backup-sync error="备份存储位置的存储桶名称\“gs://bucketname/\”不得包含“/”(如果使用前缀，请将其放入“前缀”字段中)” error.file="/go/src/github.com/vmware-tanzu/velero/pkg/persistence/object_store.go:110"error.function=github.com/vmware-tanzu/velero/pkg/persistence.NewObjectBackupStore logSource="pkg/controller/backup_sync_controller.go:168"

创建环境变量时，存储桶名称后面有一个“/”

看来创建环境变量时，我们不必在环境变量中添加“gs://”。

            BUCKET=bucketname

如果存储桶不存在，请创建存储桶，如下所示

  gsutil mb gs://$BUCKET/

在安装 velero 服务器期间，请勿在 velero install 命令中的存储桶名称前添加 gs://，如下所示

 velero install --provider gcp --plugins velero/velero-plugin-for-gcp:v1.1.0 --bucket $BUCKET  --secret-file ./credentials-velero

BUCKET=bucketname

$ velero backup describe backup-test-ns

在尝试新安装之前，您可能需要删除现有的 velero 安装。要卸载velero，请使用以下命令

      kubectl delete namespace -n velero
