在运行下面的部署Kubernetes Master时报错

部署Kubernetes Master
在192.168.10.249（Master）执行。

$ kubeadm init \
  --apiserver-advertise-address=192.168.10.249 \
  --image-repository registry.aliyuncs.com/google_containers \
  --kubernetes-version v1.21.1 \
  --service-cidr=10.1.0.0/16 \
  --pod-network-cidr=10.244.0.0/16

一直报下面错误

[root@k8s-01 ~]# kubeadm init   --apiserver-advertise-address=192.168.10.249   --image-repository registry.aliyuncs.com/google_containers   --kubernetes-version v1.21.1   --service-cidr=10.1.0.0/16   --pod-net

原因是：
提示拉取 registry.aliyuncs.com/google_containers/coredns:v1.8.0 这个镜像失败
使用 kubeadm config images list --config kubeadm.yml 命令查询需要下载的镜像

使用 docker images 命令查询镜像

[root@k8s-01 ~]# docker images
REPOSITORY                                                        TAG        IMAGE ID       CREATED         SIZE

发现已下载的镜像里面没有 registry.aliyuncs.com/google_containers/coredns/coredns:v1.8.0 这个镜像
使用 docker 命令拉取镜像

docker pull registry.aliyuncs.com/google_containers/coredns:1.8.0

查看上面的报错信息Kubernetes 需要的是 registry.aliyuncs.com/google_containers/coredns/coredns:v1.8.0 这个镜像，使用 docker tag 命令重命名一下

#重命名
docker tag registry.aliyuncs.com/google_containers/coredns:1.8.0 registry.aliyuncs.com/google_containers/coredns/coredns:v1.8.0
# 删除原有镜像
docker rmi registry.aliyuncs.com/google_containers/coredns:1.8.0

再次运行初始化命令

kubeadm init   --apiserver-advertise-address=192.168.10.249   --image-repository registry.aliyuncs.com/google_containers   --kubernetes-version v1.21.1   --service-cidr=10.1.0.0/16   --pod-network-cidr=10.244.0.0/16

OK
