What you’ll learn

After completing this course, you should be able to demonstrate the skills necessary to execute and build local containers, establish the health of a new OpenShift cluster, grant users and developers access to the cluster, and manage the cluster on a day-to-day basis. One major focus of the course is troubleshooting common problems that will be encountered beyond day one as users and applications use cluster resources.

You should be able to demonstrate these skills:

  • Manage containers and container images.

  • Create custom container images.

  • Describe the Red Hat OpenShift Container Platform cluster installation and update processes.

  • Troubleshoot application deployment issues.

  • Control access to projects using groups and role-based access control (RBAC).

  • Configure service and container networking.

  • Expose applications to clients external to the cluster using TLS encryption.

  • Configure network isolation between services and applications using network policies.

  • Configure application scheduling using labels and selectors.

  • Limit compute resource usage of applications with resource limits and quotas.

  • Install Kubernetes Operators with the web console.
