Course summary

  1. Infrastructure Validation:

    • Validate infrastructure prerequisites essential for an OpenShift cluster.

  2. Custom Installation:

    • Execute the OpenShift installer with custom configurations.

  3. Installation Monitoring:

    • Detailing and monitoring each stage of the OpenShift installation process.

  4. Troubleshooting Techniques:

    • Collect troubleshooting data during an ongoing installation or following a failed attempt.

  5. Post-Installation Configuration:

    • Finalize the configuration of cluster services in a freshly installed cluster.

These skills are imperative for successfully deploying and maintaining an OpenShift cluster across diverse environments.

Technology considerations

  • Please note that there is no local Instructor-Led Training (ILT) classroom available for DO322. All training modalities for this course require access to cloud-based classrooms.
  • Red Hat OpenShift Installation Lab (DO322): Cloud-based course with internet access requirement.
