【Docker&Containerd】使用docker pull 和crictl pull命令拉取镜像导入至本地仓库

文章目录

场景需求说明

因docker镜像下载受阻。

登录亚马逊云控制台，创建EC2实例

SSH连接EC2实例

bash 复制代码

C:\Users\xyb>ssh -i <密钥.pem> ec2-user@<公网IP地址/弹性IP地址>

安装Docker

bash 复制代码

[root@ip-10-0-10-183 ~]# yum install -y docker


[root@ip-10-0-10-183 ~]# systemctl daemon-reload
[root@ip-10-0-10-183 ~]# systemctl start docker && systemctl enable docker

使用SecureFX传输工具拉取镜像至本地

上传镜像至本地服务器中

使用crictl命令导入镜像

bash 复制代码

docker pull docker.io/calico/kube-controllers:v3.26.1
#docker拉取镜像
 
docker save -o kube-controllers.tar docker.io/calico/kube-controllers:v3.26.1
#docker导出镜像
 
ctr -n k8s.io  image import cni.tar  docker.io/calico/cni:v3.25.0

ctr -n k8s.io  image import cni.tar  registry.aliyuncs.com/google_containers/cni:v3.25.0
#ctr导入镜像
 
crictl images
#查看镜像是否导入成功
 
kubectl get pod -A -o wide	
#查看pod是否运行
 
sudo scp kube-controllers.tar k8s@node1:/home/k8s
#把docker导出的包传到其它节点


#使用ctr命令指定命名空间导入镜像
ctr -n=k8s.io image import cni.tar

#查看镜像，可以看到可以查询到了
crictl images

[root@node01 ~]# kubectl get pods -n kube-system
