Common day-2 operations with Tanzu Kubernetes Grid

Now that we have a fully configured and running TKG foundation on AWS, let’s learn how to perform some of the day-2 operations on it. TKG makes these operations very trivial as they do all the heavy lifting behind the scenes:

• Scale a cluster to add or remove nodes
• Upgrade a cluster to bump up the Kubernetes version
• Delete a cluster
• Delete the entire TKG foundation

Let’s start by scaling the workload cluster so that it has three worker nodes instead of just one.

Scaling a Tanzu Kubernetes Grid cluster

Run the following commands to scale the workload cluster we created:

1. Switch the kubectl context so that it’s pointing to the management cluster that we previously created, which we used to create the workload cluster:

   $ kubectl config use-context tkg-aws-mgmt-cluster-admin@tkg-aws-mgmt-cluster

2. Ensure that the workload cluster has only one worker node by running the following...
