Lab Wrap-up and Summary

In completing this lab you will have performed the following tasks:

Hosted Cluster Deployment:

  1. We reviewed the prerequisites required to deploy an OpenShift on OpenShift cluster with Hosted Control Planes.

  2. We made use of Red Hat Advanced Cluster Management for Kubernetes to deploy our OpenShift on OpenShfit cluster.

  3. We explored our deployed cluster, including the control plane pods and node pools that it is composed of.

Configuration:

  1. We configured authentication for our cluster from the hosting cluster environment.

  2. We tested our authentication method, and applied authorization configurations to our hosted cluster environment.

    1. Scaling:

  3. We deployed an application in our hosted cluster, demonstrating that processes are the same as any other OpenShift deployment.

  4. We configured our node pools to autoscale when resources are unavaialable to meet application requests.

  5. We scaled our application up to multiple replicas, triggering an autoscale event.

  6. We deleted our deployment and observed the cluster autoscale back down once extra resources weren’t required.

    1. Cluster Upgrades:

  7. We explored the different methods available to us to upgrade our hosted cluster, or our entire fleet of clusters.

  8. We performed a cluster upgrade using Red Hat Advanced Cluster Management for Kubernetes.
