kubeasz恢复k8s的etcd集群数据

基于kubeasz进行数据备份和恢复

查看pod状态

root@k8s-master01:/etc/kubeasz# kubectl get pod -o wide
NAME        READY   STATUS    RESTARTS   AGE   IP               NODE              NOMINATGATES
net-test1   1/1     Running   1          23h   172.100.85.197   192.168.139.235   <none> 
net-test2   1/1     Running   1          23h   172.100.85.196   192.168.139.235   <none> 

进行数据备份

`命令查询`
root@k8s-master01:/etc/kubeasz# ./ezctl --help
......
    backup      <cluster>            to backup the cluster state (etcd snapshot)
    restore     <cluster>            to restore the cluster state from backups
......
`进行备份`
root@k8s-master01:/etc/kubeasz# ./ezctl backup k8s-01
`查看备份信息`
root@k8s-master01:/etc/kubeasz# ls clusters/k8s-01/backup/
snapshot_202401092215.db  snapshot.db

删除net-test1这个pod

root@k8s-master01:/etc/kubeasz# kubectl get pod 
NAME        READY   STATUS    RESTARTS   AGE
net-test1   1/1     Running   1          23h
net-test2   1/1     Running   1          23h
`删除pod`
root@k8s-master01:/etc/kubeasz# kubectl delete pod net-test1
root@k8s-master01:/etc/kubeasz# kubectl get pod 
NAME        READY   STATUS    RESTARTS   AGE
net-test2   1/1     Running   1          23h

恢复备份

`命令查询`
root@k8s-master01:/etc/kubeasz# ./ezctl --help
......
    backup      <cluster>            to backup the cluster state (etcd snapshot)
    restore     <cluster>            to restore the cluster state from backups
......
`执行恢复`
root@k8s-master01:/etc/kubeasz# ./ezctl restore k8s-01

验证pod信息

root@k8s-master01:/etc/kubeasz# kubectl get pod -o wide
NAME        READY   STATUS    RESTARTS   AGE   IP               NODE              NOMINATEGATES
net-test1   1/1     Running   0          23h   172.100.85.200   192.168.139.235   <none>  
net-test2   1/1     Running   1          23h   172.100.85.196   192.168.139.235   <none>
