In this reference architecture the cakephp application is used as a sample application. This sample application can be found at https://hub.openshift.com/quickstarts/73-cakephp. A list of example applications can be found at https://hub.openshift.com/quickstarts/all or in the OpenShift documentation at https://docs.openshift.com/container-platform/3.5/dev_guide/migrating_applications/quickstart_examples.html.

Access the pubic url endpoint of the OpenShift deployment at https://openshift-master.hpecloud.test:8443/console/command-line for instructions on setting up the command line interface. This link will display instructions on downloading and installing the oc commandline tools as shown in figure 33.

Figure 33: Command Line Tools

Using the oc login command, log into OpenShift using the public URL and the token available from the console command-line interface described above.

oc login https://openshift-master.hpecloud.test:8443 --token=zQN6GDIPOWpklX-Lq4DCCL2CMRRI5jdCYEYIjW5GofA

CakePHP Sample Application

Create a new Project

Use the oc new-project command to create a new OpenShift Container Platform project for the application.

$ oc new-project my-app
Now using project "my-app" on server "https://openshift-master.hpecloud.test:8443".
You can add applications to this project with the 'new-app' command. For example, try:
    oc new-app centos/ruby-22-centos7~https://github.com/openshift/ruby-ex.git
to build a new example application in Ruby.

Create a new Application

Create a new application by executing the oc new-app command and specifying the git repository for the cakephp application.

$ oc new-app https://github.com/openshift/cakephp-ex.git --name=cakephp
--> Found image 79f7d44 (3 weeks old) in image stream "openshift/php" under tag "7.0" for "php"
    Apache 2.4 with PHP 7.0
    -----------------------
    Platform for building and running PHP 7.0 applications
    Tags: builder, php, php70, rh-php70
    * The source repository appears to match: php
    * A source build using source code from https://github.com/openshift/cakephp-ex.git will be created
      * The resulting image will be pushed to image stream "cakephp:latest"
      * Use 'start-build' to trigger a new build
    * This image will be deployed in deployment config "cakephp"
    * Port 8080/tcp will be load balanced by service "cakephp"
      * Other containers can access this service through the hostname "cakephp"
--> Creating resources ...
    imagestream "cakephp" created
    buildconfig "cakephp" created
    deploymentconfig "cakephp" created
    service "cakephp" created
--> Success
    Build scheduled, use 'oc logs -f bc/cakephp' to track its progress.
    Run 'oc status' to view your app.

Expose the Application

Create a route to expose the application using the subdomain that was created during the OpenShift Container Platform deployment and the oc expose command. In our example the subdomain specified was paas.hpecloud.test .

$ oc expose svc cakephp

Access the Application

The cakephp application can now be accessed via a browser, in our example the URL for the cakephp application is http://cakephp-my-app.paas.hpecloud.test/.
