GKE群集的velero备份失败

Question

我正在尝试使用velero创建GKE Cluster的备份。我在GKE Cluster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  

我执行了以下命令以启动备份

$ 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了

$ velero backup describe cluster1-backup

日志显示以下

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

我在启用Master Authorized Networks的SharedVPC上使用public GKE Cluster35.235.240.0/20.有什么解决问题的建议吗？

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="Error getting backup store for this location" backupLocation=default controller=backup-sync error="backup storage location's bucket name "gs://bucketname/" must not contain a '/' (if using a prefix, put it in the 'Prefix' field instead)" 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"/">

似乎在创建环境变量时，我们不必添加"；gs://"；在环境变量中。

BUCKET=bucketname

如果bucket不存在，则创建如下所示的bucket

gsutil mb gs://$BUCKET/

在安装velero服务器时，不要在velero install命令的bucket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
