Nutanix Karbon

To Reproduce

On Nutanix Prism Central, enable Karbon (managed Kubernetes offering of Nutanix) by following the instructions mentioned below:

1. Log on to Prism Central.
2. Click the menu icon.
3. In the Services option, click Karbon.
4. Karbon is successfully enabled message will indicate that Karbon has been enabled successfully.
5. In the Karbon Console, a message directs you to download a node OS image.
6. Once image download completes successfully, use the UI cluster create wizard to fill up all the necessary information: a) Name of cluster b) Network to be used. c) Choose development cluster or production cluster. d) Select 1.21.x as the K8s version to be deployed. e) Select the storage container. f) Initiate cluster creation. g) UI will display the status of deployment.

Next, follow the steps to install a fresh cluster, choosing v1.21 as the Kubernetes version and centos as the base image.

Once the cluster is deployed, you can download the kubeconfig to your local machine using the steps described:

1. In the Clusters view, select a cluster from the list by checking the adjacent box.
2. Click the Actions drop-down.
3. Click Download Kubeconfig
4. Under Instructions, click Download.
5. Once the file is downloaded(example: prod1-kubectl.cfg), run the following command: export KUBECONFIG=/path/to/prod1-kubectl.cfg
6. Run the following command to test the cluster: kubectl cluster-info

Then, build Sonobuoy(the standard tool for running these tests) by running go get -u -v github.com/vmware-tanzu/sonobuoy. This would build the latest Sonobuoy release v0.55.1.

Deploy a Sonobuoy pod to the deployed cluster using sonobuoy run, which will initiate the tests to run on the cluster. Use sonobuoy status to track the status of the test run. Once it completes, you can inspect the logs using sonobuoy logs and/or retrieve it using sonobuoy retrieve to copy from the main Sonobuoy pod to a local directory.
