Before we can change that let's go to the CLI and actually delete our existing deployment, let's first go to our project directory and then type Helm delete dash dash purge nodeserver so it removes our instance. The dash dash purge option both removes the deployment and any history of that deployment that exists and we'll see the use of that history later on in this video, now that we've done that we can return to our project, and we can change that replicaCount to two and hit save. Once we've done that, we can now reinstall our app using Helm install. We can now see that our deployment is looking to deploy two containers, so we'll have under pods, two entries each of which is now starting. If we type Helm…
