安装minikube

Install kubectl binary with curl on Linux
　　https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/
minikube
　　https://minikube.sigs.k8s.io/docs/start/

遇到的问题：

X Exiting due to MK_USAGE: 'none' driver does not support 'minikube ssh' command

解决：

adduser alpha
usermod -aG docker alpha && newgrp docker
su - alpha
minikube start --driver=docker

kubectl get pods

　　ImagePullBackOff

The status ImagePullBackOff means that a Pod couldn’t start because Kubernetes could not pull a container image. The ‘BackOff’ part indicates that Kubernetes will keep trying to pull the image, with an increasing back-off delay.

原因：! minikube was unable to download gcr.io/k8s-minikube/kicbase:v0.0.27, but successfully downloaded docker.io/kicbase/stable:v0.0.27 as a fallback image

，应该是镜像拉取不下来。

解决：

minikube start --image-mirror-country cn --iso-url=https://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/iso/minikube-v1.5.0.iso --registry-mirror=https://pe3ox7bd.mirror.aliyuncs.com --driver=docker --memory=2048

Create a sample deployment and expose it on port 8080:

kubectl create deployment hello-minikube --image=registry.cn-hangzhou.aliyuncs.com/google_containers/echoserver:1.4
 
kubectl expose deployment hello-minikube --type=NodePort --port=8080

访问：NodePort

kubectl get svc

minikube service mysvc， url浏览器访问　　

执行

minikube tunnel

报错：

errors: 
                minikube: no errors
                router: no errors
                loadbalancer emulator: no errors

解决：

Please keep in mind that minikube tunnel session must be opened whole the time otherwise your LB will stop getting IP address.
