Kubernetes介绍：http://kubernetes.io/docs/getting-started-guides/

github地址：https://github.com/kubernetes/kubernetes

在ubuntu上安装文档官方地址：http://kubernetes.io/docs/getting-started-guides/ubuntu/

 

环境：

• Master:
  • Ubunut14.04
  • 192.168.27.135(NAT) 　　　　　　　　
• Minion1:
  • Ubuntu14.04
  • 192.168.27.136(NAT) 
• Minion2:
  • Ubuntu14.04
  • 192.168.27.137(NAT) 

 

准备工作：

需要在三个节点上安装docker和ssh，安装ssh：

$ sudo apt-get install openssh-server$ sudo service ssh start

安装docker:

sudo apt-get install docker-engine

 

安装Kubernetes：

1、在Master上，首先创建一个工作目录，执行：

$ git clone https://github.com/kubernetes/kubernetes.git

 

2、下载完后，进入kubernetes目录，修改kubernetes/cluster/ubuntu/config-default.sh文件：

root@192.168.127.135 root@192.168.27.136 root@192.168.27.137

 

3、安装kubernetes：

$ cd  kubernetes/cluster $ KUBERNETES_PROVIDER=ubuntu ./kube-up.sh

 

成功安装的截图如下：

遇到的各种坑：

1、重启master节点，如何恢复？

这个问题弄了我至少3小时才搞定，因为我是准备直接重新执行一遍上面步骤的第三步，也就是再执行一次kube-up.sh，然而我发现每次该脚本都会从github上下载etcd、flanneld和kubernetes包，这个包有1.4G大小，可想而知要耽误多少时间。然后我就只能慢慢找这段脚本在哪执行的，最后发现在kubernetes/cluster/ubuntu/下的download-release.sh，也就是下图中的文件。所以我就把文件的内容改了，改成下面代码中的样子，目的是不让它每次都下。随后呢，我的做法是把第一次成功安装的文件备份一下，也就是把kubernetes/cluster/ubuntu/binaries这个目录备份起来，然后直接拷到重启后的master的对应目录。然后再执行kube-up.sh，之后就OK啦！
