I was doing this tutorial here https://www.udemy.com/course/introduction-to-kubernetes-on-aws-with-labs and trying to setup a kubernetes cluster in AWS. I was also cross referencing the documentation https://ubuntu.com/kubernetes/docs/quickstart... I got to the part of running juju deploy charmed-kubernetes ... I did this and logged into my AWS console and noticed 12XL ec2 instances spun up. This would have cost 3200$ if I left it running for a month so I terminated the instances immediately. What is the correct way to use juju deploy charmed-kubernetes to spin up the most minimal amount of resources required for a functioning kubernetes cluster in AWS? I want to know this for the sake of a personal enrichment tutorial undertaking. Maybe along the lines of 1 master node and 2 worker nodes utilzing t2.micro/nano instances....Thanks
