root@node1:~# virsh list --all

 1     minikube                       running
 virsh list --all

1.安装kvm

参考:
https://github.com/kubernetes/minikube/blob/master/docs/drivers.md#kvm-driver

apt-get install libvirt-bin qemu-kvm -y
usermod -a -G libvirt $(whoami)
newgrp libvirt


apt-get install qemu-kvm qemu-system libvirt-bin  bridge-utils -y
apt-get install virt-manager -y

2.安装二进制minikube&&kubectl

参考:https://github.com/kubernetes/minikube

curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.22.2/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x ./kubectl && mv ./kubectl /usr/local/bin/kubectl

注:v0.22.2现在好像minikubev0.22.3了.

3.安装二进制docker-machine-kvm

参考:https://github.com/dhiltgen/docker-machine-kvm

https://github.com/dhiltgen/docker-machine-kvm/releases
https://github.com/dhiltgen/docker-machine-kvm/releases/download/v0.10.0/docker-machine-driver-kvm-ubuntu16.04

• 注: 我on个的Ubuntu17.06,这里二进制包依旧用u16的.

• 注:关于以上二进制安装,包放在/usr/local/bin.并+x

4.设置使用kvm驱动

minikube config set vm-driver kvm

支持安装完毕,minikube start即可.

• 安装docker

sudo add-apt-repository    "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
apt-get update
apt-get install docker-ce -y

• 一些所需的image

• minikube一条蛇使用

$ minikube status  #查看minikube的状态
$ minikube stop    #关闭cluster
$ minikube delete  #删除集群
$ minikube dashboard #minikube自带dashboard,开启命令


启动一个echoserver pod
$ kubectl run hello-minikube --image=gcr.io/google_containers/echoserver:1.4 --port=8080

通过NodePort暴露的服务
$ kubectl expose deployment hello-minikube --type=NodePort

检查pod是否启动并运行
$ kubectl get pod

通过curl测试服务是否可访问
$ curl $(minikube service hello-minikube --url)
