title: What's a safe minimum disk size for a production Kubernetes node?
body: <p>I was playing around with Kubernetes on AWS with t2.medium EC2 instances having 20GB of disk space and one of the nodes ran out of disk space after a few days. It seems to be caused by a combination of Docker images and logs. </p>
  
  <p>From what I've read, Kubernetes has its own Docker GC to manage Docker's disk usage, and log rotation. I'm guessing 20GB is not enough for Kubernetes to self-manage disk usage. What's a safe disk size for a production environment?</p>
