验证集群升级的下一版本

kubeadm upgrade plan

三台master都执行

yum install -y kubeadm-1.24.17 --disableexcludes=kubernetes

master1上执行
执行升级命令（这一步需要等待）

kubeadm upgrade apply v1.24.17

master2上执行

kubeadm upgrade node

master3上执行

kubeadm upgrade node

master1上执行

kubectl drain d0-dev-master001 --ignore-daemonsets
yum install -y kubelet-1.24.17 kubectl-1.24.17 --disableexcludes=kubernetes
echo 'KUBELET_KUBEADM_ARGS="--container-runtime=remote --container-runtime-endpoint=unix:///run/containerd/containerd.sock --pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:3.7"' >/var/lib/kubelet/kubeadm-flags.env
systemctl daemon-reload
systemctl restart kubelet
kubectl uncordon d0-dev-master001

master2上执行

kubectl drain d0-dev-master002 --ignore-daemonsets
yum install -y kubelet-1.24.17 kubectl-1.24.17 --disableexcludes=kubernetes
echo 'KUBELET_KUBEADM_ARGS="--container-runtime=remote --container-runtime-endpoint=unix:///run/containerd/containerd.sock --pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:3.7"' >/var/lib/kubelet/kubeadm-flags.env
systemctl daemon-reload
systemctl restart kubelet
kubectl uncordon d0-dev-master002

master3上执行

kubectl drain d0-dev-master003 --ignore-daemonsets
yum install -y kubelet-1.24.17 kubectl-1.24.17 --disableexcludes=kubernetes
echo 'KUBELET_KUBEADM_ARGS="--container-runtime=remote --container-runtime-endpoint=unix:///run/containerd/containerd.sock --pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:3.7"' >/var/lib/kubelet/kubeadm-flags.env
systemctl daemon-reload
systemctl restart kubelet
kubectl uncordon d0-dev-master003

其它node上可以同时执行

yum install -y kubeadm-1.24.17 --disableexcludes=kubernetes
kubeadm upgrade node

##任意master执行驱逐命令（这个要保证有pod可以有资源运行）

kubectl drain d0-dev-node001 --ignore-daemonsets

node上执行

yum install -y kubelet-1.24.17 kubectl-1.24.17 --disableexcludes=kubernetes
echo 'KUBELET_KUBEADM_ARGS="--container-runtime=remote --container-runtime-endpoint=unix:///run/containerd/containerd.sock --pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:3.7"' >/var/lib/kubelet/kubeadm-flags.env
systemctl daemon-reload
systemctl restart kubelet

##任意master执行恢复调度

kubectl uncordon d0-dev-node001
