Introduction

Welcome to another video where we will be exploring the deployment of Red Hat Fuse on the OpenShift Container Platform. In this tutorial, we will guide you through the installation process, creating your own Fuse app, and deploying it onto your OpenShift cluster. If you are interested in running Apache Camel on OpenShift, then this tutorial is perfect for you. So, let's get started.

Installing Red Hat Fuse on OpenShift Container Platform

To begin our journey, we need to refer to the product documentation for Red Hat Fuse, which can be found on access.redhat.com. Red Hat Fuse comes in different flavors, but for our purpose, we need to follow the instructions for installing Fuse on OpenShift. This guide will provide us with the necessary steps and information.

Adding Red Hat Credentials to the Cluster

Before we start the installation process, it is essential to add your Red Hat credentials to the cluster. This step is crucial in enabling you to pull images from the Red Hat registry, which are protected by a username and password. The documentation provides detailed instructions to follow, or you can refer to a blog post that covers this process.

Installing Image Streams and Templates

Once the Red Hat credentials are added, we can proceed with the installation. We begin by installing image streams, which act as pointers to Docker images used for building Red Hat Fuse apps. Next, we install templates, which are quick starts for Fuse apps. These templates are not mandatory but can be helpful for getting started quickly. Make sure to update the project name if necessary.

Installing Spring Boot 2 Templates

In this step, we install the Spring Boot 2 templates, which allow us to run Fuse on Spring Boot 2. This is using the latest major release of Spring Boot and provides additional functionality for our Fuse application.

Installing Fuse Console Templates

In the final installation step, we install templates for the Fuse console, a web app used for monitoring Fuse apps within your project. This allows for easy management and monitoring of your Fuse applications.

Creating a New Red Hat Fuse Application

After completing the installation process, we can move on to creating our own Fuse application. While there are various ways to achieve this, one of the easiest methods is by using the Fuse Launcher, a web app that generates template apps. By accessing launch.openshift.com, we can deploy an example application by selecting the Fuse template and specifying the version we want to target.

Modifying the Source Code of the Generated Application

Once the example application is downloaded, we can open it in our favorite IDE (such as IntelliJ IDEA) and make modifications to the source code. We explore the Palm file, which defines the version of Fuse, as well as dependencies and artifact repositories needed. Additionally, we can modify the Camel router class to customize our application's behavior.

Deploying the Sample App to OpenShift

To deploy our modified application to OpenShift, we follow the instructions provided in the project's README file. The fabric Maven plugin is used to build and deploy the app into OpenShift. We need to specify the base image to build our container from, which should be the Fuse base image. Once the Maven build is complete, we can test and access our deployed application.

Conclusion

Congratulations! You have successfully installed Red Hat Fuse on the OpenShift Container Platform, created a customized Fuse application, and deployed it onto your OpenShift cluster. This tutorial has provided a step-by-step guide to help you get started with Fuse development on OpenShift.
