篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Kubernetes最新版本1.15.1，shell脚本一键部署，刚刚完成测试，实用。相关的知识，希望对你有一定的参考价值。

根据上一篇博客内容，《K8S最新版本集群部署超详细（k8s版本1.5.1）docker 版本19.03.1以及基本操作和服务介绍》

由于自己一步一步安装，步骤有些不方便，今天趁着有时间，写了一个shell一键部署脚本，刚刚又测试了一遍，效果还不错，这里分享给大家。

这是我的GitHub地址，脚本放到上面了。
总共是3个脚本，一个变量脚本，一个Master节点脚本，一个Worker节点脚本。
过程截图如下：


首先贴出

1. k8s-openrc.sh脚本内容
