解决思路

把节点需要的镜像拉取了就好，这边给出本人使用的解决方法，比较拐弯莫叫，仅供参考

1. 拉取了所需要的镜像到本地

   

2. • 接下来把这个镜像制作成压缩包

   • docker save -o k.tar kubernetesui/dashboard:v2.7.0
     

3. 

4. 在当前终端运行这个来使得当前终端的镜像构建与mini kube同步，这个命令可以将本地的镜像构建同步到mini kube中我们加载本地目录下的压缩包为镜像，mini kube中也能获取到他

   eval $(minikube docker-env)
   

5. 

6. • 然后加载它

   •  docker load -i k.tar
     

7. 

8. 

9. 接下来再运行

10. minikube dashboard
    

11. 如果自动弹出失败，就把URL复制到浏览器中打开

12.
