安装 kubeadm、kubelet 和 kubectl
此步骤可选下载 kubeadm
# wget -P /usr/local/bin https://dl.k8s.io/release/v1.28.3/bin/linux/amd64/kubeadm下载 kubelet
# wget -P /usr/local/bin https://dl.k8s.io/release/v1.28.3/bin/linux/amd64/kubelet下载 kubectl
# wget -P /usr/local/bin https://dl.k8s.io/release/v1.28.3/bin/linux/amd64/kubectl添加执行权限
# chmod +x /usr/local/bin/kube*kubectl 命令补全
apt install -y bash-completionkubectl completion bash > /etc/profile.d/kubectl_completion.sh. /etc/profile.d/kubectl_completion.sh加速 minikube 下载 kubeadm、kubelet 和 kubectl
创建 minikube 工作目录
此目录会自动创建，本次手动创建是因为手动下载kubectl、kubeadm、kubelet，提速minikube的下载。# mkdir /root/.minikube/cache/linux/amd64/v1.28.3 -pv复制 kubeadm、kubelet 和 kubectl 到指定目录
# cp /usr/local/bin/kube* /root/.minikube/cache/linux/amd64/v1.28.3/minikube 创建 k8s 集群

! minikube skips various validations when --force is supplied; this may lead to unexpected behavior
* Using the docker driver based on user configuration
* The "docker" driver should not be used with root privileges. If you wish to continue as root, use --force.
* If you are running minikube within a VM, consider using --driver=none:
