I have two mac mini computers and I'm trying to create a K8s cluster using k3d. I can create a cluster on a single host very easily. However, I'm having trouble finding any guidance on creating a cluster that has multiple hosts (machines). Any ideas?
According to your question, you want to create k8s cluster with k3d on multiple hosts.
But, based on the information, described on k3d Issues page on GitHub (issue still open), this solution:
with the current version of k3 is not officially "supported"
Thus, at the moment it looks like the only version with single host is possible within k3d.
