Hello, this sounds like a reasonable ask and the team will be looking into installing via a build script on ubuntu-slim.

We will discuss internally size and maintenance costs and give an update soon.

Added note, despite low overhead, ubuntu-slim is intented to be a very light weight container for low overhead workflows. Installing K8s tools might not be the best approach or use-case of this product.

Could you explain your use-case to us in more detail to gauge interest?
