ps：deployment 跟rc 功能一样

node3、node4也要导入
[root@linux-node4 k8s]# docker load < kubernetes-dashboard-amd64-v1.5.1.tar
[root@linux-node4 k8s]# docker load < pause-amd64-3.0.tar

先拿nginx做试验
[root@linux-node3 k8s]# vim nginx-deployment.yaml
[root@linux-node3 k8s]# kubectl create -f nginx-deployment.yaml
deployment “nginx-deployment” created

[root@linux-node3 k8s]# kubectl get pods 成功
NAME READY STATUS RESTARTS AGE
nginx-deployment-1247087418-b9939 1/1 Running 5 5m
nginx-deployment-1247087418-v3ntw 1/1 Running 4 5m

[root@linux-node3 /]# kubectl get pods -o yaml -L app=nginx | grep podIP 查看上面3台IP，不过没有意义，可能重启后就还掉IP了

这里安装碰到了问题
1.由于网络模式问题 需要在vim /etc/docker/daemon.json 添加
“default-ipc-mode”: “shareable” —2台都要改
2.sysctl -w vm.max_map_count=262144 系统参数要改

为了固定ip所创建
[root@linux-node3 k8s]# kubectl create -f nginx-service.yaml

root@linux-node3 k8s]# kubectl get service
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes 10.1.0.1 443/TCP 2d
nginx-demo 10.1.12.94 80/TCP 16s

安装个dashboard
[root@linux-node3 k8s]# vim kubernetes-dashboard.yaml
