使用 VS Code 阅读 Kubernetes 代码

问题：无法跳转到定义在其他文件的方法 （如下图所示）

解决方法：

1. 打开 shell
2. 安装 GO
   

   sudo apt-get update sudo apt install -y wget sudo wget https://storage.googleapis.com/golang/go1.9.2.linux-amd64.tar.gz sudo tar -xvf go1.9.2.linux-amd64.tar.gz sudo mv go /usr/local

3. GOPATH 和 GOROOT
   export GOPATH=~/k8s
   export GOROOT=/usr/local/go
   
4. 下载代码： sudo git clone https://github.com/kubernetes/kubernetes $GOPATH
5. 安装 VS Code

6. curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main" > /etc/apt/sources.list.d/vscode.list' sudo apt-get update sudo apt-get install code sudo -H -u $LOCALUSER bash -c "code --install-extension lukehoban.Go"

   安装 Docker
   

   sudo apt-get update sudo apt-get install -y \     apt-transport-https \     ca-certificates \     curl \     software-properties-common sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - sudo add-apt-repository \    "deb https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") \    $(lsb_release -cs) \    stable" sudo apt-get update && sudo apt-get install -y docker-ce=$(apt-cache madison docker-ce | grep 17.12 | head -1 | awk '{print $3}')

   
   
7. 设置Kubernetes路径
    cd $GOPATH
    ln -sf  staging/src src
    cd $GOPATH/staging/src/k8s.io
    ln -sf $GOPATH kubernetes
   
8. 编译
   cd $GOPATH
   build/run.sh make what=cmd/hyperkube
9. 直接编译Hyperkube
   cd $GOPATH/src/k8s.io/kubernetes/cmd/hyperkube
   go build -gcflags "-l -N"
10. 打开Kubernetes 代码
    code $GOPATH
    
11. 找到文件 /home/honcao/k8s/src/k8s.io/kubernetes/cmd/hyperkube/main.go
