K8s master 节点IP 地址发生变化后该怎么办？

 

systemctl stop kubelet

999 docker stop $(docker ps -q --filter name=k8s_kube-*)
1000 docker stop $(docker ps -q --filter name=k8s_etcd_*)

1001 cd /etc/kubernetes/manifests/

 

#old IP : 19.129 

#new IP : 1.129 

1003 sed -i 's/19.129/1.129/g' kube-apiserver.yaml
1005 sed -i 's/19.129/1.129/g' etcd.yaml

1005 sed -i 's/19.129/1.129/g'sed -i 's/19.129/1.129/g'

 

1027 rm -rf /etc/kubernetes/pki/apiserver.crt
1028 rm -rf /etc/kubernetes/pki/apiserver.key

1029 kubeadm init phase certs apiserver --apiserver-advertise-address=192.168.1.129 --kubernetes-version v1.20.9
1030 systemctl restart kubelet
1031 kubectl status kubelet
1032 systemctl status kubelet

kubeadm token create --print-join-command

 

 

#### 从节点

rm -rf /etc/kubernetes/{kubelet.conf,pki}

kubeadm reset --force --ignore-preflight-errors=all

kubeadm join 192.168.1.129:6443 --token xxxxx.xxxxxxxxx \
