1. 部署cri-docker （所有集群节点）

k8s从1.24版本开始移除了dockershim，所以需要安装cri-docker插件才能使用docker

软件下载：GitHub - Mirantis/cri-dockerd: dockerd as a compliant Container Runtime Interface for Kubernetes

安装

rpm -ivh  cri-dockerd-0.3.5.20231016182601.cd730ff8-0.el7.x86_64.rpm

配置cri-docker

vim /usr/lib/systemd/system/cri-docker.service[Service]
Type=notify
ExecStart=/usr/bin/cri-dockerd --container-runtime-endpoint fd:// --network-plugin=cni --pod-infra-container-image=reg.westos.org/k8s/pause:3.7systemctl daemon-reload
systemctl  enable --now cri-docker
ll /var/run/cri-dockerd.sock

2. 升级master节点

docker load -i k8s-v1.24.17.tar
docker images | grep k8s
docker push reg.westos.org/k8s/kube-apiserver:v1.24.17
docker push  reg.westos.org/k8s/kube-proxy:v1.24.17
docker push reg.westos.org/k8s/kube-scheduler:v1.24.17
docker push reg.westos.org/k8s/kube-controller-manager:v1.24.17
docker push reg.westos.org/k8s/pause:3.7

yum install -y kubeadm-1.24.17-0
kubeadm upgrade plan

kubectl edit nodes k8s1kubeadm.alpha.kubernetes.io/cri-socket: unix:///var/run/cri-dockerd.sockkubeadm upgrade apply v1.24.17

配置kubelet使用cri-docker

vim /var/lib/kubelet/kubeadm-flags.env
KUBELET_KUBEADM_ARGS="--pod-infra-container-image=reg.westos.org/k8s/pause:3.7 --container-runtime=remote --container-runtime-endpoint=unix:///var/run/cri-dockerd.sock"

systemctl daemon-reload 
systemctl  restart kubelet 

kubectl uncordon k8s1

3. 升级worker节点

升级kubeadm  执行升级

yum install -y kubeadm-1.24.17-0
kubeadm upgrade node

腾空节点   #需要在master节点执行

kubectl drain k8s2 --ignore-daemonsets
kubectl drain k8s3 --ignore-daemonsets

yum install -y kubelet-1.24.17-0 kubectl-1.24.17-0

vim /var/lib/kubelet/kubeadm-flags.env
KUBELET_KUBEADM_ARGS="--pod-infra-container-image=reg.westos.org/k8s/pause:3.7 --container-runtime=remote --container-runtime-endpoint=unix:///var/run/cri-dockerd.sock"

systemctl daemon-reload 
systemctl  restart kubelet 

kubectl uncordon k8s2

k8s1、k8s2、k8s3在配置前需要重置节点

kubeadm reset
kubeadm reset  --cri-socket unix:///var/run/cri-dockerd.sock
kubeadm reset  --cri-socket unix:///var/run/cri-dockerd.sock

k8s1:

k8s2,3

所有节点清除iptables规则

iptables -F
iptables -F -t nat

systemctl  disable --now docker
systemctl  disable --now docker.socket
systemctl  disable --now cri-docker
