The template creates a pipeline to deploy a Java application.
It uses an S2I image builder and the S2I binary strategy to upload the artifact generated in the pipeline.
The pipeline creates the resources for the application if they don't exist.
The main goal is to show that a template can create a pipeline which in turn creates the resources needed for the deployment.
The template can be created in any project with the following commands:
oc create -f java-app-template.yaml -n openshift
With the command above the template is created in the project openshift.
After its creation it's possible to create an application using the OpenShift catalog selecting the Java Application template.
A form is presented to be completed with information about the application like the Git repository, Git branch and the application name:
Using the oc CLI tool a demonstration can be made with the following commands:
oc new-app --template=java-app-template -p PARAM_APP_NAME=greeter-service -p PARAM_GIT_REPO=https://github.com/leandroberetta/greeter-service
As a result a BuildConfig of type JenkinsPipeline is created:
--> Deploying template "openshift/java-app-template" to project dev
* With parameters:
* Application Name=greeter-service
* Git Repository=https://github.com/leandroberetta/greeter-service
* Git Branch=master
* Webhook Secret=qMCMmPiadIYl4dLoMOnGgQVoouPrE2mEg6qSOyh6 # generated
--> Creating resources ...
buildconfig "greeter-service-pipeline" created
--> Success
Use 'oc start-build greeter-service-pipeline' to start a build.
Run 'oc status' to view your app.
Then a build can be started:
oc start-build greeter-service-pipeline
The final result is the application deployed into an specific project:
