Guided Exercise: Navigate the OpenShift Web Console

Access an OpenShift cluster by using its web console and identify pages about key OpenShift cluster services.

Outcomes

Explore the features and components of Red Hat OpenShift by using the web console.
Create a sample application by using the Developer perspective in the web console.
Switch to the Administrator perspective and examine the resources that are created for the sample application.
Use the web console to describe the cluster nodes, networking, storage, and authentication.
View the default cluster operators, pods, deployments, and services.

As the student user on the workstation machine, use the lab command to prepare your system for this exercise.

This command ensures that the cluster is validated for the exercise.
