pause 容器对应版本3.6--->3.7--->3.7--->3.8--->3.9
三台master都执行
| Code Block |
|---|
yum install -y kubeadm-1.24.17 --disableexcludes=kubernetes |
任一master执行验证集群能否升级
| Code Block |
|---|
kubeadm upgrade plan |
master1上执行
执行升级命令（这一步需要等待）
| Code Block |
|---|
kubeadm upgrade apply v1.24.17 |
master2上执行
| Code Block |
|---|
kubeadm upgrade node |
master3上执行
| Code Block |
|---|
kubeadm upgrade node |
master1上执行
| Code Block |
|---|
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
| Code Block |
|---|
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
sed -i 's#sandbox_image = ".*"#sandbox_image = "registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.7"#' /etc/containerd/config.toml
systemctl daemon-reload
systemctl restart kubelet
kubectl uncordon d0-dev-master002 |
master3上执行
| Code Block |
|---|
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
| Code Block |
|---|
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）
| Code Block |
|---|
kubectl drain d0-dev-node001 --ignore-daemonsets |
node上执行
| Code Block |
|---|
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
| Code Block |
|---|
kubectl uncordon d0-dev-node001 |
注意：如果nide上有运行ceph集群的osd节点的话需要将osd节点先out待数据平衡完成之后才能停止容器runtime
