+=== Argo Rollouts CLI
+
+Argo Rollouts provides a link:https://kubernetes.io/docs/reference/kubectl/[kubectl,window='_blank'] extension to support
+working with rollouts. link:https://argo-rollouts.readthedocs.io/en/stable/installation/#kubectl-plugin-installation[Instructions, window='blank']
+for installing the extension are available here however note that this has already been done for you in this workshop.
+
+The extension is well link:https://argo-rollouts.readthedocs.io/en/stable/features/kubectl-plugin/[documented,window='_blank']
+and provides a number of commands and these can be used with our currently deployed rollout.
+
+To view the rollout we just deployed, run the following command:
+
+[.console-input]
+[source,bash,subs="attributes+,+macros"]
+----
+oc argo rollouts get rollout rollouts-demo -n user%USERNUM%-prod
+----
+
+This command should output something similar to the following:
+
+[.console-output]
+[source,bash,subs="attributes+,+macros"]
+----
+Name:            rollouts-demo
+Namespace:       user1-prod
+Status:          ✔ Healthy
+Strategy:        BlueGreen
+Images:          quay.io/openshiftdemos/rollouts-demo:blue (stable, active)
+Replicas:
+  Desired:       2
+  Current:       2
+  Updated:       2
+  Ready:         2
+  Available:     2
+
+NAME                                       KIND        STATUS     AGE    INFO
+⟳ rollouts-demo                            Rollout     ✔ Healthy  6m46s

+      └──□ rollouts-demo-66d84bcd76-k67q4  Pod         ✔ Running  6m46s  ready:1/1
+----
+
+With this command we can view the status of the rollout, `Healthy` here, as well as
+the ReplicaSets and Pods that are associated with the rollout.
+
+To view the status of the rollout by itself you can use the following command:
+
+[.console-input]
+[source,bash,subs="attributes+,+macros"]
+----
+oc argo rollouts status rollouts-demo -n user%USERNUM%-prod
+----
+
+This should return a simple `Healthy` in the output. Other commands are available to perform
+actions on the rollout such as a promoting a rollout, aborting a rollout, etc. A complete
+list of commands can be viewed with the `--help` switch and we will look at some of them
+during the course of this workshop.
