**系统**

[root@kubernetes-build k8s.io]# cat /etc/redhat-release 
    CentOS Linux release 7.4.1708 (Core)

**安装docker git**

yum install docker git -y

**clone 代码**

[root@kubernetes-build k8s.io]# git clone https://github.com/kubernetes/kubernetes.git
    正克隆到 'kubernetes'...

    remote: Compressing objects: 100% (155/155), done.
    remote: Total 779809 (delta 87), reused 61 (delta 61), pack-reused 779593
    接收对象中: 100% (779809/779809), 554.88 MiB | 1.61 MiB/s, done.
    处理 delta 中: 100% (533318/533318), done.
    Checking out files: 100% (16584/16584), done.

**切换分支**

[root@kubernetes-build kubernetes]# git checkout v1.10.4 
    Note: checking out 'v1.10.4'.
    
    You are in 'detached HEAD' state. You can look around, make experimental
    changes and commit them, and you can discard any commits you make in this
    state without impacting any branches by performing another checkout.
    
    If you want to create a new branch to retain commits you create, you may
    do so (now or later) by using -b with the checkout command again. Example:
    
      git checkout -b new_branch_name
    
    HEAD 目前位于 5ca598b... Merge pull request #64631 from msau42/automated-cherry-pick-of-#64351-upstream-release-1.10
    [root@kubernetes-build kubernetes]# git checkout v1.10.4 
    HEAD 目前位于 5ca598b... Merge pull request #64631 from msau42/automated-cherry-pick-of-#64351-upstream-release-1.10
    [root@kubernetes-build kubernetes]# git status
    # 头指针分离于 v1.10.4
    无文件要提交，干净的工作区

**编译**

打镜像hyperkube镜像

生成的镜像

[root@kubernetes-build hyperkube]# docker images 
    REPOSITORY                                       TAG                           IMAGE ID            CREATED              SIZE

这个时候可以打tag对应的镜像仓库了  
接下来就是搭建镜像仓库了
