k3d创建k3s集群

安装go

wget https://golang.google.cn/dl/go1.21.3.linux-amd64.tar.gz
tar zxvf go1.15.3.linux-amd64.tar.gz
mv go /usr/local/

vim /etc/profile在最结尾添加

export HOME=/root
export GOROOT=/usr/local/go
export GOPATH=/opt/idcus/go
export PATH=$PATH:$GOPATH/bin:$GOROOT/bin

source /etc/profile
go version #查看是否生效
go env -w GOPROXY=https://goproxy.cn,direct #go设置镜像源

安装k3d

安装k3d

go install github.com/k3d-io/k3d/v5@latest

查看版本

root@BZD27274:~# k3d --version
k3d version v5-dev
k3s version v1.21.7-k3s1 (default)

使用k3d

由于我使用的是wsl2，提前在windows上安装了dockerdesktop，因此自带kubectl

创建/删除demo集群

k3d cluster create demo
k3d cluster delete demo
k3d cluster list
