编译kubernetes二进制文件

编译kubectl、kubelet、kubeadm等二进制命令

现在kubernetes主流版本是1.8，官网下载go，版本需大于1.9，编译主机内存4G，6G剩余磁盘空间（2g内存，磁盘空间小于6g是不会成功的）

https://github.com/kubernetes/community/blob/master/contributors/devel/development.md

https://kubernetes.io/docs/setup/release/building-from-source/

https://github.com/kubernetes/kubernetes/tree/master/build/

go1.9.2.linux-amd64.tar.gz
tar -xf go1.9.2.linux-amd64.tar.gz -C /usr/local
export PATH=$PATH:/usr/local/go/bin
yum install gcc rsync -y

获取最新的源码

go get -d k8s.io/kubernetes
cd go/src/k8s.io/kubernetes

或者GitHub按版本标签下载指定版本的源码，解压后进入目录开始编译

附：

1，选择某一个版本编译

export GOPATH=~/
go get github.com/whateveruser/whateverrepo
cd ~/src/github.com/whateveruser/whateverrepo
git tag -l
# supose tag v0.0.2 is correct version
git checkout tags/v0.0.2
go run whateverpackage/main.go

2，关于GOPATH和GOROOT

Edit your ~/.bash_profile to add the following line:

export GOPATH=$HOME/go

Save and exit your editor. Then, source your ~/.bash_profile.

source ~/.bash_profile

Note: Set the GOBIN path to generate a binary file when go install is run.

export GOBIN=$HOME/go/bin

GOPATH环境变量是为了列出了寻找Go代码的地方

export GOTPAHT = {源代码路径，src的上一级文件夹}

想要把go安装到哪个目录，就

export GOROOT=目录路径
