Kalm does not seem to like k3s :(

I'm having this problem as well. I'm using K3s v1.18.12+k3s1 and Kalm v0.1.0-alpha.5. This causes kalm pod restart and make the interface unusable.

Here the logs:

We have updated the readme file and make a new installation flow, and I have installed kalm with k3s on mac, it should work😄
