这篇文章整理以下kubernetes离线安装二进制文件所需地址。并以此为基础展开后续安装和特性的确认。

所需内容

安装需要如下二进制文件：

• kubernetes-server相关二进制
• docker二进制
• etcd二进制
• cfssl相关二进制文件
• cni相关二进制文件

下载脚本

将下载连接进行管理，并将下载下的二进制文件中需要用到的部分进行分类存放，可以使用如下脚本，同时也放到github的easypack中了。

[root@host shell]# cat step0-get-binaries.sh

网络条件不好的话，可能需要根据脚本中的动作自己进行下载/解压和mv操作了。
