minikube安装记录
本文是Linux Ubuntu虚拟机内部使用none driver安装minikube
1. 安装docker-ce并配置docker代理
配置HTTP/HTTPS代理
感谢万恶的墙，只有再祖国才有机会体会。注意一定要配置no_proxy，否则minikube安装后期访问kubeapiservers就会出错了， 除非你的代理是反向代理到你的虚拟机
set_proxy(){
export HTTP_PROXY=http://10.71.84.78:1080
export HTTPS_PROXY=http://10.71.84.78:1080
export NO_PROXY="localhost"
}
minikube 安装
minikube start --vm-driver none --alsologtostderr --v 7
使用none driver安装，加上日志输入，能清楚看到minikube安装的步骤。
通过jourctl -ef -u kubelet查看日志输入，能看到具体错误出现在了哪个过程
通过命令行输出，可以看到minikube主要是调用kubeadm init命令去创建一个极简k8s环境的。

etcd bind出错
使用docker logs $id 查看etcd出错的原因：

发现etcd listen的时候总是到一个未知的地址
k8s issue 57709中讨论到
ubuntu 16.04的dns解析是跳过了本地，虽然我虚拟机上直接用ping localhost是正常的，但是使用
nslookup localhost则是解析到了另外一个地址。
一个简单的做法就是把/etc/resolve.conf里的search注释掉。
