# 1.安装wsl
注意
1.wsl --set-default-version 2
2.需要开启Hyper-V，wsl2以来该功能，如果没有Hyper-V选项管理员运行以下脚本
pushd "%~dp0" dir /b %SystemRoot%\servicing\Packages\*Hyper-V*.mum >hyper-v.txt for /f %%i in ('findstr /i . hyper-v.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i" del hyper-v.txt Dism /online /enable-feature /featurename:Microsoft-Hyper-V-All /LimitAccess /ALL1

# 2.安装Ubuntu
--- Windows store安装 搜索windows subsystem linux安装，该方式默认安装在C盘，不推荐 --- 切换其他盘安装(E盘) 创建文件夹，此处使用Linux 下载Ubuntu，具体的Linux发行版可切换1

80注意
如果启用镜像网络模式后GoLand无法调试wsl2中的程序，镜像模式下必须采用的是127.0.0.1地址访问wsl2中的应用，但IDE自带的dlv工具采用的是0.0.0.0，体现为报错 waring layer=rpc Listening for remote connections (connections are not authenticated nor encrypted)。
--- dlv源码获取
git clone https://github.com/go-delve/delve -b 1.21
--- 修改delve\cmd\dlv\cmds\commands.go的execute函数，替换全局调试地址
func execute(attachPid int, processArgs []string, conf *config.Config, coreFile string, kind debugger.ExecuteKind, dlvArgs []string, buildFlags string) int {
addr = strings.ReplaceAll(addr, "0.0.0.0:", "127.0.0.1:")
...
}
--- 打包编译后替换GoLand下plugins\go-plugin\lib\dlv\linux下的dlv可执行文件
CGO_ENABLED=0 GOOS=linux go build -o dlv cmd/dlv/main.go
# 6.Kind搭建集群
--- 下载Kind curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.11.1/kind-linux-amd64 chmod +x ./kind sudo mv ./kind /usr/local/bin/kind --- 创建集群 kind create cluster --name=k8sdbg --- 验证集群状态 kubectl cluster-info --context k8sdbg1
