不得不说的话：2019年1月4日，注定让我难忘，也注定要改变些什么！我所做的事只是为了在2019年的7月份可以找到一份工作，不至于我毕业就失业了。我爱运维吗？不爱！为什么一直在这条路上，无非是上了贼船还由得我选吗？

今天早上9点不到就开始了学习：Kubeadm初始化Kubernetes集群  我看到过前辈们在这块知识点上费了很多时间，所以我做好了用一天的时间来完成这块知识点。视频时间1小时24分整。我目前知道的是有三种方法可以部署kubernetes集群，前辈也和我建议过用二进制部署的方法即符合公司要求也可以少踩很多坑。可我想既然视频买了，书也买了，总不能不学一下吧，于是我决定先跟视频和书走一遍再二进制部署一遍再ansible部署一遍。事实证明，真的踩了许多坑，踩坑是高兴的，因为我做好了准备

中午想去吃饭，可看到错误还在那里，怎么也迈不动腿，随性坐下继续排错。今天啊从早上9点不到到下午17点52分，上了一趟厕所，其余的时间都在部署。终于成功了，心中很是开心。下面的路还有太多未知的坑，我愿意一个一个的来踩。

下面给出我在本次部署中的所有代码，不是懒得整理，我放出来只是想告诉我自己，这就是我今天所做的一切！！！

主机名 IP 作用
master 10.0.0.100 master节点
node01 10.0.0.101 node节点
node02 10.0.0.102 node节点

kubeamd

1.master, nodes:安装kubelet, kubeadm, docker

2.master:kubeadm init

3.nodes:kubadm join

前提：时间一致；防火墙关闭，SElinx 关闭；
