kubernetes - GKE 集群的 velero 备份失败
问题描述
我正在尝试velero
创建GKE Cluster
. 我安装成功GKE Cluster
如下图
$ 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
我执行了下面的命令来启动备份
$ 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了
$ velero backup describe cluster1-backup
Name: cluster1-backup
Namespace: velero

日志显示以下内容
$ velero backup logs cluster1-backup
An error occurred: timed out waiting for download URL
我在public GKE Cluster
仅 启用到 35.235.240.0/20的情况下SharedVPC
使用。Master Authorized Networks
有什么建议可以解决这个问题吗?
解决方案
现在问题已解决
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,桶名后有一个“/”
似乎在创建环境变量时,我们不必在环境变量中添加“gs://”。
BUCKET=bucketname
如果存储桶不存在,则创建存储桶,如下所示
gsutil mb gs://$BUCKET/
安装velero服务器时,命令中的bucket名称前不要加gs://,velero install
如下图
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
Name: backup-test-ns

在尝试新安装之前,您可能需要删除现有velero
安装。要卸载velero
使用以下命令
kubectl delete namespace -n velero
