OpenShift v3

In our first exercise, we deployed on the test server via the build pipeline of Jenkins. It’s also possible to deploy through Docker at Smals and the console (or CLI).

Add deployments folder

<plugin>

   <groupId>org.apache.maven.plugins</groupId>

   <artifactId>maven-war-plugin</artifactId>

   <configuration>

   <outputDirectory>${basedir}/../.openshift/deployments</outputDirectory>

   </configuration>

</plugin>

Create your docker image 

1) Start Docker at Smals

2) Go to the project folder

cd /c/dev/prj/trainings-project/hellostco/

3) Build your image

docker build -t container-snapshot.smals.be/trainings-hellostco:tst .

4) Copy your new image to artifactory

docker push container-snapshot.smals.be/trainings-hellostco:tst

Add your project in Openshift

To add a project in Openshift, you must use the CLI command.

Open a DOS command and go to the C:\dev\prj\trainings-project\hellostco\.openshift\resource folder.

Add dc

Add your deployement configuration.

oc create -f dc.yaml

And verify with the command 

oc get dc

Modify the number of pod and put 1.

oc edit dc trainings-helloXX

Verify the number of pod.

oc get pod | grep XX

Add service

Add your service.

oc create -f svc.yaml

And verify with the command 

oc get service

Add route

Add your route.

oc create -f route.yaml

And verify with the command 

oc get route

Now, Openshift knows the application but the application is not deployed.

You must add a deployment.

oc deploy trainings-helloXX --latest

You can check the deployment with the event. You can filter with the event "Created" or you userId.

oc get events --watch | grep Created

You can check the result.

oc get pods | grep [userId]

After the name of the dc, you have the number of the deployment.

Or

oc deploy trainings-hellostco

With the console

You can also deploy with the GCloud console. You must click on Deploy button in deployment view

In the console Openshift, you have the log and a terminal for jboss container.

In the console, you can check the folder but also execute the command. For example, a curl to see if your application respond.

Command : curl http://$HOSTNAME:8080/trainings-hellostco-jsf/
