Lab Wrap-up and Summary

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

Hosted Cluster Deployment:

  • We reviewed the prerequisites required to deploy an OpenShift on OpenShift cluster with hosted control planes.

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

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

Configuration:

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

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

Scaling:

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

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

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

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

Cluster Upgrades:

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

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