Getting Hands-On Experience with OpenShift
Hands-on experience is one of the most essential aspects of preparing for the Red Hat OpenShift EX280 certification exam. Since the exam is performance-based, it evaluates your ability to complete practical tasks within a live OpenShift environment, rather than just testing theoretical knowledge. The exam will require you to deploy applications, scale services, configure networking and storage, and troubleshoot issues—tasks that are all best learned through practical, real-world experience.
The first step to gaining hands-on experience is setting up your OpenShift environment. While there are several ways to do this, the most practical and flexible approach is using OpenShift’s local development tool, OpenShift Local (previously known as Minishift). This tool allows you to set up a local OpenShift cluster on your machine, providing an environment where you can practice deploying and managing applications without needing access to a cloud service or enterprise-level OpenShift cluster. OpenShift Local is a great way to get started with the basics and become familiar with the OpenShift platform.
If you have the resources, deploying OpenShift in a cloud environment is another valuable approach. Managed OpenShift services like OpenShift Dedicated or Red Hat OpenShift on AWS (ROSA) offer pre-configured clusters that you can use for practice. These platforms allow you to deploy a fully managed OpenShift instance where you can explore all of the features available to you in a production environment, including networking, security configurations, and multi-cloud integrations. Working with a cloud-based cluster offers more flexibility for scaling and deploying complex workloads, helping you prepare for tasks you might encounter on the exam.
Once your OpenShift environment is set up, begin by exploring the platform and getting comfortable with its tools and interfaces. One of the first things to familiarize yourself with is the OpenShift CLI (Command Line Interface), which will be your primary tool during the exam. While the OpenShift web console is user-friendly and useful for certain tasks, the exam is designed to test your ability to navigate OpenShift using the command line. Therefore, proficiency with basic commands such as oc create, oc apply, oc get, oc delete, and oc expose is essential. You’ll be using these commands to manage resources like pods, deployments, services, and routes.
Begin with basic commands to create and manage resources. For example, practice deploying simple applications by creating deployment configurations, managing pods, and setting up services to expose those applications to users. Deploying sample applications, such as a basic web application or a multi-tier application, will help you gain hands-on experience with important OpenShift objects like Deployments, ReplicaSets, and Pods.
The OpenShift platform also includes more advanced features that you will need to understand for the exam. One of the key areas is application scaling. OpenShift supports both horizontal scaling (scaling out by adding more pod replicas) and vertical scaling (scaling up by increasing the resources allocated to each pod). Practice scaling your applications based on resource utilization by adjusting the number of replicas or changing the resource allocation for each container. This practice will help you understand the OpenShift mechanisms for managing applications under varying load conditions, which is likely to be tested in the exam.
In addition to scaling, you should also focus on configuring storage and persistent data in OpenShift. Understanding how to manage Persistent Volumes (PVs) and Persistent Volume Claims (PVCs) is crucial, as the EX280 exam often requires candidates to configure storage for applications. Practice creating PVs, PVCs, and configuring access modes (ReadWriteOnce, ReadOnlyMany, etc.) to understand how data can persist across pod restarts. You should also practice setting up StatefulSets, which are specifically designed for applications that require persistent storage and stable network identities.
Security is another area that requires hands-on practice. OpenShift offers several built-in security features to protect applications and containers, including Role-Based Access Control (RBAC), Security Context Constraints (SCCs), and Network Policies. Familiarize yourself with these tools by practicing how to set up secure access for users, control which actions are allowed on specific resources, and configure security policies for containers running within your OpenShift cluster. Configuring and managing these security policies is often part of the exam, so hands-on experience is essential.
Networking is another key area to focus on. OpenShift uses Kubernetes networking to provide both internal and external communication between containers and external services. It is important to practice setting up and managing OpenShift routes, which are used to expose services externally. You should also become familiar with Service Discovery and Ingress controllers, as these are critical components for managing traffic between services in a multi-container application. Understanding how to create and manage routes for HTTP and HTTPS traffic is vital for completing tasks related to application access during the exam.
Troubleshooting is one of the most important skills to develop for the EX280 exam. During the exam, you will encounter tasks that involve diagnosing and fixing issues in a live OpenShift environment. These could range from application deployment issues to problems with networking, storage, or pod configurations. It’s essential to practice using the OpenShift CLI to troubleshoot common problems. Familiarize yourself with commands like oc logs, oc describe, and oc status, which can help you identify and resolve issues. You should also practice using oc debug, which allows you to troubleshoot running pods by entering a debug container and inspecting logs or system configurations in real time.
Another important troubleshooting skill is understanding how to monitor the health of OpenShift components. Use OpenShift’s integrated monitoring tools to examine logs, metrics, and events. You should practice checking pod statuses and investigating issues such as resource exhaustion, network failures, and misconfigured applications.
The more time you spend in an OpenShift environment, the more confident you will become in navigating the platform and solving issues under time constraints. Hands-on practice also provides you with a deeper understanding of how OpenShift components work together, which is essential for troubleshooting problems effectively.
After you feel comfortable with the basics, move on to more complex tasks such as setting up CI/CD pipelines with OpenShift and integrating OpenShift with external tools for automated deployments. Practice configuring and using OpenShift’s internal registry, managing images, and building and deploying container images from Dockerfiles. These tasks can often appear in the exam, especially when dealing with complex applications that require automated workflows for building, testing, and deploying code.
By practicing these tasks extensively, you’ll gain the practical experience needed to efficiently complete exam tasks during the actual Red Hat OpenShift EX280 certification exam.
