KubeKey 部署 k8s All-in-One 环境

k8s 版本: v1.24.1

容器运行时: containerd v1.6.9

安装命令：

./kk create cluster --with-kubernetes v1.24.1 --container-manager containerd

KubeKey - github 官网

FA&Q

由于 k8s 1.24 版本不支持使用 docker 作为容器运行时，所以需要安装 containerd

1. 错误日志
E1101 17:25:53.177065   27816 remote_image.go:218] "PullImage from image service failed" err="rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.ImageService" image="registry.cn-beijing.aliyuncs.com/kubesphereio/pause:3.7"
FATA[0000] pulling image: rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.ImageService

2. 解决方案
vim /etc/containerd/config.toml # 注释掉 disabled_plugins = [“cri”] 

# 替换 containerd 默认的 sand_box 镜像，编辑 /etc/containerd/config.toml
sandbox_image = "registry.aliyuncs.com/google_containers/pause:3.2"

systemctl daemon-reload
systemctl restart containerd

安装了 dokcer 或者 containerd 之后会默认禁用 CRI
