利用阿里云镜像仓库

1. 创建镜像仓库
   
2. 绑定代码仓库，并设置海外构建
   
   3.创建完成后，即可自动拉取git仓库代码，依据git仓库一级目录下Dockerfile文件自动构建镜像
   方法简介。
   
   内置规则中，只需要 tag 名字为 release-v$version ，即构建 tag 为 $version 的镜像出来。

4自动拉取脚本
参考github： github地址

# 1 方法1
bash -c "`curl -ssLf https://raw.githubusercontent.com/a001189/scripts/master/imagepull.sh `" -O  ${IMAGE:TAG}
# 2 方法2
curl -ssLf https://raw.githubusercontent.com/a001189/scripts/master/imagepull.sh > imagepull.sh&&bash imagepull.sh ${IMAGE:TAG}

示例

[root@jenkins ~]# bash -c "`curl -ssLf https://raw.githubusercontent.com/a001189/scripts/master/imagepull.sh `" -O k8s.gcr.io/kube-controller-manager:v1.14.1
开始构建并拉取镜像 k8s.gcr.io/kube-controller-manager:v1.14.1
