如果镜像拉不下来 则手动装载镜像

```shell
# 阿里云获取 保存镜像
IMAGE_NAME=metrics-scraper
IMAGE_PATH=docker.io/kubernetesui/$IMAGE_NAME
TAG=v1.0.8
docker pull $IMAGE_PATH:$TAG
docker save $IMAGE_PATH:$TAG -o ${IMAGE_NAME}_$TAG.tar

IMAGE_NAME=dashboard
IMAGE_PATH=docker.io/kubernetesui/$IMAGE_NAME
TAG=v2.7.0
docker pull $IMAGE_PATH:$TAG
docker save $IMAGE_PATH:$TAG -o ${IMAGE_NAME}_$TAG.tar

IMAGE_NAME=metrics-server
IMAGE_PATH=registry.cn-hangzhou.aliyuncs.com/google_containers/$IMAGE_NAME
TAG=v0.6.4
docker pull $IMAGE_PATH:$TAG
docker save $IMAGE_PATH:$TAG -o ${IMAGE_NAME}_$TAG.tar
```

上传镜像到本地

```shell
# 宿主机执行
eval $(minikube docker-env)

# 导入镜像
IMAGE_NAME=metrics-scraper
TAG=v1.0.8
docker load < ${IMAGE_NAME}_$TAG.tar

IMAGE_NAME=dashboard
TAG=v2.7.0
docker load < ${IMAGE_NAME}_$TAG.tar

IMAGE_NAME=metrics-server
