Additional Resources

You recently joined the DevOps team at your company and have been tasked with investigating one of the Kubernetes clusters that is used for testing and development. This will require you to determine any additional admission controller that have been enabled and any that have been disabled. Once you determine which admission controllers are enabled, you will need to gain information about the resources that have been created for the dev and test namespaces.
