部署应用
先创建一个工程，工程project和Kubernetes的命名空间是一对一的，应用都需要部署在工程中。
使用镜像直接部署应用。
我们选择Apache HTTP Server (httpd)镜像。
点击Deploy按钮部署该应用。
可查看已经部署的应用。
应用的deployments资源。
应用的pods资源。
应用的services资源。
OpensShift监控应用。
可以在命令行查看，注意工程project和命名空间namespace是一对一的。
oc get all -nhello

为了在集群外能否访问集群内应用，需要添加Route，OpenShift使用HAProxy实现Router的。
netstat -lntp | grep haproxy
tcp 0 0 127.0.0.1:10443 0.0.0.0:* LISTEN 125023/haproxy
tcp 0 0 127.0.0.1:10444 0.0.0.0:* LISTEN 125023/haproxy
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 125023/haproxy
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 125023/haproxy

我们创建一个Route。
通过命令行可以看到增加一条路由。
oc get all -nhello

Check if the URL path was typed correctly and that the route was created using the desired path.
