etcd 备份还原

还原

每台的master节点 IP 和主机名需要修改 停止集群 mv /etc/kubernetes/manifests.bak

备份原有etcd数据

mv /u01/local/kube-system/etcd /u01/local/kube-system/etcd-date '+%Y%m%d-%H:%M:%S' ​

还原第一台master 

nerdctl  -n k8s.io run --rm \
-v '/tmp\:/tmp' \
-v '/u01/local/kube-system:/u01/local/kube-system' \
-v '/etc/kubernetes/pki/etcd:/etc/kubernetes/pki/etcd' \
--env ETCDCTL\_API=3 \
'docker.kedacom.com:15000/etcd:3.5.0-0' \
/bin/sh -c "etcdctl snapshot restore \
/tmp/etcd-snapshot-.db \
--name node-9xct \
--endpoints=10.165.124.13:2379 \
