K8S镜像下载报错解决方案(使用阿里云镜像去下载kubeadm需要的镜像文件)

　由于某种不可描述的问题我国网络是无法直接访问Google，YouTube等网站，因此你需要购买,自建或者在网上找一些免费的VPN工具。这不我最近在通过kubeadm部署k8s集群就遇到了想要访问”k8s.gcr.io”却无法正常访问，索性的是可以通过阿里云找到共有仓库。

一.抛出问题


　如上图所示,默认情况下是无法直接访问Google的镜像仓库”k8s.gcr.io”，此时咱们有三种解决方案:
　(1)在互联网上找一些免费的VPN进行翻墙操作或者在网上购买收费的VPN，推荐使用收费版本的，因为免费版本的VPN并不太稳定而且下载速度也并不是很理想，付费的VPN相对来说稳定性比较强,但是这种情况存在一个风险，因为你的所有操作都会被提供VPN的服务商在后台记录;
　(2)在互联网上购买VPS服务器，自己搭建VPN，前提是你购买的VPS可以访问国外的各种网站，直接购买国内的阿里云服务器可以你搭建出来VPN也是白搭,这种方案也需要掏钱，但相比于上面的那种方式安全性较强，因为你访问的记录在你的VPS中有记录，你想干啥就干啥;
　(3)我们的目的就是下载Google的镜像而已,可以在其它国内站点下载即可，而且很多国人已经很热心的提供了下载连接,如果你没有经常翻墙的需求其实没有必要采取上面两种方案(而且有很多公司也会为员工购买翻墙的工具，自己搭建VPN服务器的一般就是一些运维或开发人员喜欢干这事)。

　本篇博客采取第三种方案，直接在国内的其它网站(比如阿里云的镜像网站)下载需要的镜像，下载后给镜像重新更名为kubeadm工具指定的镜像名称即可。


二.登录阿里云账户找到k8s相关的仓库
1>.登录阿里云账户，如下图所示,点击”菜单logo”

2>.点击”产品与服务”，弹出如下图所示的对话框后再点击”容器镜像服务”

3>.如下图所示，点击”镜像搜索”,并输入搜索关键词”google_containers/kube-apiserver”

4>.查看镜像仓库信息

5>.将docker服务器的仓库设置为”阿里云镜像”

[root@master200.yinzhengjie.org.cn ~]# grep Environment /usr/lib/systemd/system/docker.service 　#温馨提示，如果你有自己的VPN是设置代理的，但是没有VPN建议将这两行注释掉
#Environment=”HTTPS_PROXY=http://www.yinzhengjie.org.cn:10086“
#Environment=”NO_PROXY=127.0.0.0/8,172.200.0.0/21”
[root@master200.yinzhengjie.org.cn ~]#
[root@master200.yinzhengjie.org.cn ~]# cat /etc/docker/daemon.json

[root@master200.yinzhengjie.org.cn ~]# systemctl daemon-reload

[root@master200.yinzhengjie.org.cn ~]# systemctl restart docker.service

三.登录阿里云并下载k8s镜像
1>.登录阿里云账号

[root@master200.yinzhengjie.org.cn ~]# docker login —username=你的阿里云账号 registry.cn-beijing.aliyuncs.com #使用咱们自己的账户登录阿里云(没有就去注册一个即可),登陆后咱们就可以从阿里云仓库下载相应的K8S镜像啦~

Login Succeeded
[root@master200.yinzhengjie.org.cn ~]#
[root@master200.yinzhengjie.org.cn ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
[root@master200.yinzhengjie.org.cn ~]#

2>.下载镜像
[root@master200.yinzhengjie.org.cn ~]# docker image pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver:v1.17.2
[root@master200.yinzhengjie.org.cn ~]# docker image pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-controller-manager:v1.17.2
[root@master200.yinzhengjie.org.cn ~]# docker image pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-scheduler:v1.17.2
[root@master200.yinzhengjie.org.cn ~]# docker image pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-proxy:v1.17.2

[root@master200.yinzhengjie.org.cn ~]# docker image pull registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.4.3-0
[root@master200.yinzhengjie.org.cn ~]# docker image pull registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.6.5

3>.查看已经下载的镜像

[root@master200.yinzhengjie.org.cn ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
