创建minio凭证文件

Code Block

cat >credentials-velero <<EOF

aws_access_key_id = adminT6uyCVYwgIJe9ZWC7fDQ
aws_secret_access_key = Uenpay@2019

安装velero

因为有些环境拉取不到国外的镜像，所以我拉到本地打了tag上传到了阿里云，没有做任何修改，可放心使用

官方的参数像是--image velero/velero:v1.9.

...

3 --plugins velero/velero-plugin-for-aws:v1.

...

安装velero

2.1

Code Block

velero install \
    --provider aws \
    --image registry.cn-hangzhou.aliyuncs.com/zhengyu1992/velero:v1.9.03 \
     --plugins registry.cn-hangzhou.aliyuncs.com/zhengyu1992/velero-plugin-for-aws:v1.62.01 \
    --namespace velero \
    --bucket velero \
    --use-volume-snapshots=false \
    --secret-file ./credentials-velero \
    --default-volumes-to-restic \
    --use-restic \
     --backup-location-config region=minio,s3ForcePathStyle="true",s3Url=http://10.10.21.48:9000minio-headless.mid \
    --wait

卸载velero

Code Block
kubectl delete namespace/velero clusterrolebinding/velero kubectl delete crds -l component=velerovelero uninstall

迁移storageclass，我们的目的是将nfs-storage中的数据迁移到rook-ceph-block

...

Code Block

vi change-storage-class-config.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: change-storage-class-config
  namespace: velero
  labels:
    velero.io/plugin-config: ""
    velero.io/change-storage-class: RestoreItemAction
data:
  nfs-storage: rook-ceph-block

kubectl create -f change-storage-class-config.yaml

开始备份

velero backup create mybackup --include-resources pvc,pv zadig-20230717 --include-namespaces defaultzadig

查看备份进度

velero backup describe mybackupzadig-20230717

查看备份日志

velero backup logs mybackupzadig-20230717

这时候到minio控制台可以看到有数据已经写入了

删除原有的pvc，否则恢复的时候会提示冲突

kubectl delete pvc persistence-rabbitmq-cluster-server-0 persistence-rabbitmq-cluster-server-1 persistence-rabbitmq-cluster-server-2

恢复pv数据Image Added

#仅备份pv和pvc的参数(适用于仅更换存储类不迁移集群的情况)

velero backup create test--include-resources pvc,pv --include-namespaces zadig

velero restore create --from-backup mybackup

这里可以看到rabbitmq-cluster-server的storageclass已经变成了rook-ceph-block

Image Removed

我们尝试去启动pod<backup-name> --namespace-mappings <source-namespace>:<target-namespace>
