oc new-app命令非常强大。它是特定于openshift的，因此在默认的Kubernetes中不可用，但是当您开始学习Kubernetes时，它非常有用。下面以一个快速命令开始，创建一个相当复杂的应用程序：
- oc new-project -n example
- oc new-app -f https://raw.githubusercontent.com/openshift/origin/master/examples/quickstarts/cakephp-mysql.json
使用oc new-app，你可以从OpenShift开发人员那里获取模板，运行上述命令后，Kubernetes命名空间(在OpenShift中)将由一组新的、已定义的资源填充。
- oc get all
输出如下：
- NAME READY STATUS RESTARTS AGE
- pod/cakephp-mysql-example-1-build 0/1 Completed 0 4m
- pod/cakephp-mysql-example-1-gz65l 1/1 Running 0 1m
- pod/mysql-1-nkhqn 1/1 Running 0 4m
-
- NAME DESIRED CURRENT READY AGE
- replicationcontroller/cakephp-mysql-example-1 1 1 1 1m
- replicationcontroller/mysql-1 1 1 1 4m
-
- NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
- service/cakephp-mysql-example ClusterIP 172.30.234.135 <none> 8080/TCP 4m
- service/mysql ClusterIP 172.30.13.195 <none> 3306/TCP 4m
-
- NAME REVISION DESIRED CURRENT TRIGGERED BY
- deploymentconfig.apps.openshift.io/cakephp-mysql-example 1 1 1 config,image(cakephp-mysql-example:latest)
- deploymentconfig.apps.openshift.io/mysql 1 1 1 config,image(mysql:5.7)
-
- NAME TYPE FROM LATEST

- route.route.openshift.io/cakephp-mysql-example cakephp-mysql-example-example.2886795271-80-rhsummit1.environments.kata
这样做的好处是，你可以删除pod，观察复制控制器重新创建它们等。你还可以使用该模板将其用于更改其他应用程序。
