minikube可以被部署到虚拟机中，也可以部署成一个容器。本文将介绍如何使用Docker部署minikube。

前提条件

安装并配置如下的软件：

• WSL 2；
• Docker Desktop for Windows；

安装

1. 把docker设置成默认的驱动：

   minikube config set driver docker
   

2. 以管理员身份运行CMD，并执行如下脚本：

   minikube start --driver=docker --image-mirror-country=cn
   

   如果出现* Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default，就说明安装成功！

常见问题

1. error execution phase wait-control-plane: couldn't initialize a Kubernetes cluster

   此时，Docker Desktop已创建好minikube容器，在容器内部执行journalctl -xeu kubelet或journalctl -r -n 500 -u kubelet命令查看详细的错误日志，如下：

   Jul 20 08:47:02 minikube kubelet[3433]: E0720 08:47:02.968896    3433 pod_workers.go:951] "Error syncing pod, skipping" err="failed to \"CreatePodSandbox\" for \"kube-apiserver-minikube_kub

   rs)" pod="kube-system/kube-apiserver-minikube"
   

   由此可见，原因是拉取k8s.gcr.io/pause:3.6失败。国内的通病！

   解决方法：

   1. 首先，在容器内部执行如下命令：

      docker image pull registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.6
      docker image tag registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.6 k8s.gcr.io/pause:3.6
      systemctl stop kubelet
      systemctl start kubelet
      

   2. 然后，在CMD中重启minikube：

      minikube stop
      minikube start
