This hands on experience will introduce you to developing on OpenShift. Learn how to access OpenShift from the command line, deploy an existing Spring application, and scale up your application to handle increased web traffic.

For the best experience in this learning path, we suggest that you complete the following learning resources in the order shown. When you click on a resource, it will open in a new tab. Keep this page open so you can easily move on to the next resource!

The workshop is hosted in an OpenShift environment that is running on a public cloud. The environment consists of master node(s), worker or "application" nodes, and Dynamic Provisioned Storage

Learn how to manage your application through the web console along with the command line interface.

Projects are a top level concept to help you organize your deployments. Learn how to use a few different commands to make sure that things in the environment are working as expected. Don’t worry if you don’t understand all of the terminology as we will cover it in detail in later labs.

In this lab, we’re going to deploy the web component of the ParksMap application which is also called parksmap and uses OpenShift’s service discovery mechanism to discover the backend services deployed and shows their data on the map.

Services provide a helpful abstraction layer to group similar pods, making it easier to scale your application.

Observe some edge cases where you might want some Pods and an RS without a D or a Service, and others

Learn how to set up routes so that people and services outside of OpenShift can access your application.

Learn how to examine a pod's logs directly from the web console or via the command line.

It is generally not recommended to modify the content of a container through SSH or running custom commands inside the container. Nevertheless, in some use-cases, such as debugging an application, it might be beneficial to get into a container and inspect the application.

Understand how to provision access to your application.

Learn how OpenShift builds container images using source code from an existing repository. This is accomplished using the Source-to-Image project.

Learn how to deploy and connect a MongoDB database where the nationalparks application will store location information. We will mark the nationalparks application as a backend for the map visualization tool, so that it can be dynamically discovered by the parksmap component using the OpenShift discovery mechanism and the map will be displayed automatically.

Learn how to use the web console to add probes to our nationalparks application.

Learn how to configure a pipeline in OpenShift to manage application lifecycles.

Learn how to use web hooks to automate with pipelines.

Troubleshooting with Process Automation Management 2

Learn how to debug your application.

Keen to build web applications for the cloud? Get a quick hands-on introduction to OpenShift®, the open source Platform as a Service (PaaS) offering from Red Hat®. With this practical guide, you’ll learn the steps necessary to build, deploy, and host a complete real-world application on OpenShift without having to slog through long, detailed explanations of the technologies involved.

For many organizations, a big part of DevOps’ appeal is software automation using infrastructure-as-code techniques. This book presents developers, architects, and infra-ops engineers with a more practical option. You’ll learn how a container-centric approach from OpenShift® can help your team deliver quality software through a self-service view of IT infrastructure.
