将 kubernetes 从 1.23.5 升级至 1.24,container runtime 也从 docker 切换到 containerd,kubelet 已正常启动,但集群无法启动

$ kubectl get nodes   
The connection to the server k8s-api:6443 was refused - did you specify the right host or port?

部分错误日志如下

通过 How to smoothly switch the kubernetes container runtime from docker to container 找到了解决方法,问题是无法访问 k8s.gcr.io 引起的。

打开 containerd 的配置文件 /etc/containerd/config.toml ,将 [plugins."io.containerd.grpc.v1.cri"] -> sandbox_image 的值修改为 registry.aliyuncs.com/google_containers/pause:3.6

[plugins]

  [plugins."io.containerd.grpc.v1.cri"]
    ...
    sandbox_image = "registry.aliyuncs.com/google_containers/pause:3.6"
