# 可替换$(curl -L -s https://dl.k8s.io/release/stable.txt)为指定版本号，如：v1.24.16
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
install -o docker_user -g docker -m 0755 kubectl /usr/local/bin/kubectl
kubectl version --client

minikube start  #启动minikube
#指定版本、执行镜像源
minikube start --registry-mirror=https://registry.docker-cn.com  --image-mirror-country cn --kubernetes-version=v1.24.16

# 注：如果本机配置了http_proxy，可能会遇到`You appear to be using a proxy, but your NO_PROXY environment does not include the minikube IP (ip)`，这种情况可以通过设置NO_PROXY=$(minikube ip)来解决
NO_PROXY=$(minikube ip) minikube start --registry-mirror=https://registry.docker-cn.com  --image-mirror-country cn --kubernetes-version=v1.24.16

默认为单节点，添加节点可参考：https://minikube.sigs.k8s.io/docs/commands/node
