查看kubernets集群需要的镜像包 ```bash kubeadm config images list --kubernetes-version v1.21.3 ``` 从阿里云仓库拉取镜像包 ```bash docker pull registry.aliyuncs.com/google_containers/kube-apiserver:v1.21.3 docker pull registry.aliyuncs.com/google_containers/kube-controller-manager:v1.21.3 docker pull registry.aliyuncs.com/google_containers/kube-scheduler:v1.21.3 docker pull registry.aliyuncs.com/google_containers/kube-proxy:v1.21.3 docker pull registry.aliyuncs.com/google_containers/pause:3.4.1 docker pull registry.aliyuncs.com/google_containers/etcd:3.4.13-0 docker pull registry.aliyuncs.com/google_containers/coredns:1.8.0 ``` 给镜像包设置别名 ```bash docker tag registry.aliyuncs.com/google_containers/kube-apiserver:v1.21.3 k8s.gcr.io/kube-apiserver:v1.21.3 docker tag registry.aliyuncs.com/google_containers/kube-controller-manager:v1.21.3 k8s.gcr.io/kube-controller-manager:v1.21.3 docker tag registry.aliyuncs.com/google_containers/kube-scheduler:v1.21.3 k8s.gcr.io/kube-scheduler:v1.21.3 docker tag registry.aliyuncs.com/google_containers/kube-proxy:v1.21.3 k8s.gcr.io/kube-proxy:v1.21.3 docker tag registry.aliyuncs.com/google_containers/pause:3.4.1 k8s.gcr.io/pause:3.4.1 docker tag registry.aliyuncs.com/google_containers/etcd:3.4.13-0 k8s.gcr.io/etcd:3.4.13-0 docker tag registry.aliyuncs.com/google_containers/coredns:1.8.0 k8s.gcr.io/coredns/coredns:v1.8.0 ```
