安装

kubectl: brew instlal kubectl
kube: brew cask install minikube

镜像问题

针对 minikube v0.23.0

运行启动 minikube 和登入虚拟机后

minikube start
minikube ssh

手动拉取镜像：

镜像拉取完毕，确认 pods 状态都是运行后，启动 dashboard

minikube dashboard

如要停止，运行

minikube stop

诊断

查看 pods 定位问题

状态：kubectl get pods --all-namespaces
详细状态：kubectl describe pods --all-namespaces

以下是一个最终状态：
