How can I choose a name for my application on OpenShift - kubernetes

Question

I deployed my application on Openshift using the commands:
oc project <projectname>
Then I navigate to my application's directory and use the command:
mvn fabric8:deploy -Popenshift
This deploys to Openshift perfectly.
The only problem is that it automatically names my application and I am not sure where it is getting the name from. I want to change it to [app-name]-test, [app-name]-dev, etc
So, where does it get the application name from and how can I change it?

Answer 1

It's usually in your fabric8 XML configuration (pom.xml). For example:
<configuration>
<!-- Standard d-m-p configuration which defines how images are build, i.e. how the docker.tar is created -->
<images>
<image>
<name>${image.user}/${project.artifactId}:${project.version}</name>
<!-- "alias" is used to correlate to the containers in the pod spec -->
<alias>camel-service</alias>
<build>
<from>fabric8/java</from>
<assembly>
<basedir>/deployments</basedir>
<descriptorRef>artifact-with-dependencies</descriptorRef>
</assembly>
<env>
<JAVA_LIB_DIR>/deployments</JAVA_LIB_DIR>
<JAVA_MAIN_CLASS>org.apache.camel.cdi.Main</JAVA_MAIN_CLASS>
</env>
</build>
</image>
</images>
<!-- resources to be created -->
<resources>
<!-- Labels that are applied to all created objects -->
<labels>
<group>quickstarts</group>
</labels>
<!-- Definition of the ReplicationController / ReplicaSet. Any better name than "containers" ? -->
<deployment>
<!-- Name of the replication controller, which will have a sane default (container alisa, mvn coords, ..) -->
<!-- Override here -->
<name>${project.artifactId}</name>
...
It defaults to ${project.artifactId} but you can override with whatever you'd like with something like ${project.artifactId}-dev. You can also edit the deployment manually in Kubernetes:
$ kubectl edit deployment ${project.artifactId}
