国内镜像源
Azure China提供了目前用过的质量最好的镜像源，涵盖了docker.io，gcr.io，quay.io。无论是速度还是覆盖范围，体验都极佳。而且都支持匿名拉取，也就是不需要登录。这点特别友好。azk8s.cn支持的镜像代理转换如下列表。
| global | proxy in China | format | example |
|---|---|---|---|
| dockerhub (docker.io) | dockerhub.azk8s.cn | dockerhub.azk8s.cn//: | dockerhub.azk8s.cn/microsoft/azure-cli:2.0.61 dockerhub.azk8s.cn/library/nginx:1.15 |
| gcr.io | gcr.azk8s.cn | gcr.azk8s.cn//: | gcr.azk8s.cn/google_containers/hyperkube-amd64:v1.13.5 |
| quay.io | quay.azk8s.cn | quay.azk8s.cn//: | quay.azk8s.cn/deis/go-dev:v1.10.0 |
Note:
k8s.gcr.iowould redirect togcr.io/google-containers, following image urls are identical:
k8s.gcr.io/pause-amd64:3.1
gcr.io/google_containers/pause-amd64:3.1
k8s.gcr.io/pause-amd64:3.1
gcr.io/google_containers/pause-amd64:3.1
这里，我开发了一个小的脚本azk8spull，这个脚本可以自动根据镜像名称进行解析，转换为azure的mirror镜像源域名。并进行拉取。拉取完成后会自动进行tag重命名为原本的镜像名。该脚本已经开源在 https://github.com/xuxinkun/littleTools#azk8spull 上。以下是使用样例。
安装 azk8spull
git clone https://github.com/xuxinkun/littleTools
cd littleTools
chmod +x install.sh
./install.sh
source /etc/profile
git clone https://github.com/xuxinkun/littleTools
cd littleTools
chmod +x install.sh
./install.sh
source /etc/profile

kubeadm源
kubeadm直接使用阿里云的源即可。速度也比较快。
