Feature Request: command to return version of k3s supported

[anuaimi]

I use k3sup to create k3s clusters. These clusters are long living so they need to be upgraded periodically. While it is easy to query a cluster to see what version it is based on, there is no easy way to know when k3sup supports a new version of k3s. It would be great to have a command that returns what version of k3s it installs. It might be as simple as adding the k3s version to the output of k3sup version

Expected Behaviour

k3sup version

Current Behaviour

Possible Solution

Steps to Reproduce (for bugs)

Context

I'm creating a tool that sits on top of k3sup. It will create the VMs (on a number of popular public clouds), run k3sup on each node. It will also update k3sup and see if there is a new version of k3s. If so, it will upgrade each of the clusters (using a rolling update).

Your Environment

• What Kubernetes distribution are you using (for k3sup app)?

kubectl version

• What OS or type or VM are you using for your cluster? Where is it hosted? (for k3sup install/join):
  DO

• Operating System and version (e.g. Linux, Windows, MacOS):
  MacOS

uname -a

cat /etc/os-release

Hi @anuaimi thank you for your interest in the project.

Have you thought about running kubectl version to see what version your cluster is running at?

How would you see your solution working? I noticed you didn't fill out "Possible Solution", would you mind doing so?
