In this lab, you will learn how to take an existing Spring Boot application that has been converted to use RHOAR (Red Hat OpenShift Application Runtimes). RHOAR is a collection of Red Hat Supported Microservice Framworks optimized for deployment on OpenShift. See http://launch.openshift.io for more information on the complete set of languages/technologies supported.
The Spring Boot application we will be deploying is a basic Product Catalog MVC Web App, using a PostgreSQL DB for persistence. You can review the updates made to the original Spring application to use the RHOAR framework components at https://github.com/rhoar-enablement/spring/blob/master/lab4/docs/lab4-instructions.adoc .
For the purpose of this lab we will walk you through how to take the completed Spring Boot/RHOAR project and deploy it to OpenShift. Before starting, ensure you have forked and cloned this repo into a local working directory and have the ability to create or access a personal OpenShift project for this Lab.
-
Login to the remote OpenShift environment (Get instructions from your OpenShift admin)
-
Create a new project with a unique name or ensure an existing OpenShift project is selected
oc new-project product-catalog-<unique number> or oc project <your-project-name>
-
Create a Postgres database
oc new-app -e POSTGRESQL_USER=luke -ePOSTGRESQL_PASSWORD=secret -ePOSTGRESQL_DATABASE=my_data openshift/postgresql --name=my-database
-
Build and deploy your project (ensure you are in the /lab directory of your local repo)
mvn clean fabric8:deploy -Popenshift
-
Login to the OpenShift Web Console (Get URL from your OpenShift admin)
-
From the Web Console Home Page, scroll down and select the Project used for this Lab
-
From the Overview Page of your Project, you should see the following Applications and Components running once they have completed deployment:
-
Within the product-catalog application, open the URL from the created Route in another browser tab and verify the Spring application is working:
