三台master都执行其中一台master执行
| Code Block |
|---|
yum install -y kubeadm-1.27.6* --disableexcludes=kubernetes |
...
| Code Block |
|---|
kubeadm upgrade apply v1.27.6 |
其它master上执行
| Code Block |
|---|
yum install -y kubeadm-1.27.6* --disableexcludes=kubernetes
kubeadm upgrade node |
master1上执行master升级
| Code Block |
|---|
hostname=d0-dev-master001 kubectl drain $hostname --ignore-daemonsets yum install -y kubelet-1.27.6* kubectl-1.27.6* --disableexcludes=kubernetes sed -i 's#sandbox_image = ".*"#sandbox_image = "registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.9"#' /etc/containerd/config.toml echo '' >/var/lib/kubelet/kubeadm-flags.env echo '' >/etc/sysconfig/kubelet systemctl daemon-reload systemctl restart containerd systemctl daemon-reload systemctl restart kubelet kubectl uncordon $hostname |
其它master上执行，多个master需要一个个执行
| Code Block |
|---|
hostname=d0-dev-master002
kubectl drain $hostname --ignore-daemonsets
|
等一台结束后通过kubectl get node查看对应的master是否已经变成v1.27.6，再去执行另外一台master，依次升级完所有master节点
node上升级
| Code Block |
|---|
yum install -y kubeadm-1.27.6* kubelet-1.27.6* kubectl-1.27.6 --disableexcludes=kubernetes* kubeadm upgrade node sed -i 's#sandbox_image = ".*"#sandbox_image = "registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.9"#' /etc/containerd/config.toml echo '' >/var/lib/kubelet/kubeadm-flags.env echo '' >/etc/sysconfig/kubelet systemctl daemon-reload systemctl restart containerd systemctl daemon-reload systemctl restart kubelet kubectl uncordon $hostname |
其它node上可以同时执行
| Code Block |
|---|
hostname=d0-dev-node001 kubectl drain $hostname --ignore-daemonsets kubeadm upgrade node yum install -y kubelet-1.27.6 kubectl-1.27.6 --disableexcludes=kubernetes sed -i 's#sandbox_image = ".*"#sandbox_image = "registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.9"#' /etc/containerd/config.toml echo '' >/var/lib/kubelet/kubeadm-flags.env echo '' >/etc/sysconfig/kubelet systemctl daemon-reload systemctl restart containerd systemctl daemon-reload systemctl restart kubelet kubectl uncordon $hostname |
注意：如果node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
