Learn to build and deploy applications on OpenShift in our Classroom and Online DO288 | EX288 Training at WebAsha Technologies. It is based on OpenShift 4.22and teaches the hands-on skills tested in the performance-based EX288 exam.
Training overview:
The DO288 EX288 training covers developing and deploying applications on OpenShift: container image builds, Source-to-Image, application configuration, health probes, deployment strategies, Helm and Kustomize packaging, and Tekton CI/CD pipelines. You practise on OpenShift 4.22 labs, working against the clock as you would in the exam.
Intended audience:
This course suits application developers, DevOps engineers and platform developers who deploy applications on OpenShift and want Red Hat's cloud-native developer credential.
Topics covered:
-
Deploy applications on OpenShift: Deploy and manage applications with the web console and the oc command line.
-
Source-to-Image (S2I): Build container images straight from source code with S2I.
-
Application configuration: Keep configuration and sensitive data in ConfigMaps and Secrets.
-
Health probes: Add readiness, liveness and startup probes so that OpenShift can tell when an application is healthy.
-
Helm & Templates: Deploy multi-container applications with templates, Helm charts and Kustomize.
-
Tekton CI/CD pipelines: Design, configure and trigger CI/CD pipelines with OpenShift Pipelines (Tekton).
-
Images and builds: Build container images, publish them to a registry and manage OpenShift builds.
-
Troubleshoot deployments: Diagnose and fix problems with builds and application deployments.
Requirements:
You should understand basic container technology and be comfortable with the Linux and oc command line. Online participants need a stable internet connection and a laptop or desktop for the live OpenShift cloud labs, where the EX288 skills are practised.
Prerequisites:
Red Hat recommends completing DO188 (Containers with Podman) / EX188 or having equivalent knowledge of containers. Red Hat says RHCSA is helpful for command-line work but is not required. It also lists DO288 as recommended preparation for EX288.
Career benefits:
Companies that run their applications on OpenShift hire developers with the EX288 credential. In India, packages typically range from ₹6 LPA to ₹30+ LPA in roles such as OpenShift Developer, Cloud-native Developer and DevOps Engineer. The credential is also a step on Red Hat's Cloud-native Applications certification track.
