看到这里，求知欲饥渴难耐的你一定在想，怎么部署的我们应用程序到集群里面去呢？来个简单的，只需要两步:(这里本文使用nginx镜像当我们的应用程序，因为nginx 简单，运行起来后直接可以用浏览器访问网页了。)
第一步：在master 节点上创建一个deployment
kubectl create deployment nginx --image=nginx效果如下，可以看到一个叫nginx的deployment创建成功了。
root@ubuntu:/home/cong# kubectl create deployment nginx --image=nginx deployment.apps/nginx created root@ubuntu:/home/cong# kubectl get deployments NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE nginx 1 1 1 1 11m第二步：创建一个service
kubectl create service nodeport nginx --tcp 80:80效果如下，可以看到一个叫nginx的service创建成功了，这里kubectl get svc是kubectl get services的简写。
root@ubuntu:/home/cong# kubectl create service nodeport nginx --tcp 80:80 service/nginx created root@ubuntu:/home/cong# kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 3d nginx NodePort 10.107.237.157 <none> 80:30601/TCP 11s在slave节点上执行下面的命令验证一下nginx有没有部署成功。
curl localhost:30601 或者 curl kube-slave:30601效果如下:
root@ubuntu:/home/cong# curl localhost:30601 <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { width: 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working. Further configuration is required.</p> <p>For online documentation and support please refer to <a href="http://nginx.org/">nginx.org</a>.<br/> Commercial support is available at <a href="http://nginx.com/">nginx.com</a>.</p> <p><em>Thank you for using nginx.</em></p> </body> </html>用浏览器打开试试，nginx的首页显示出来了。
简单吧，是不是信心大增了？！
为了练习更多复杂的命令，我们将上面建好的deployments/nginx, services/nginx 删除先，命令如下：
root@ubuntu:/home/cong# kubectl delete deployments/nginx services/nginx deployment.extensions "nginx" deleted service "nginx" deleted
