I've got an issue with k3d on ArchLinux with my firewalld configuratuion.

kubectl cluster-info

returned a valid config but

kubectl get pods

showed all bootstrap containers in

CreatingContainer

state.

After a bit of digging I found that it was just networking issue with newer

firewalld

, so I had to create

firewalld

zone, fix some subnet with

k3d cluster create <name> --subnet cidr

, add that network as source to relevant zone with

firewall-cmd --zone=docker --add-source cidr

, add a policy to forward traffic from

docker

zone and add a masquerading to outgoing zone (`home`/`work`/`public` depending on configuration for inet interface). I hope my experience would help somebody if you have similar networking conf.

👋 I guess you found https://github.com/k3d-io/k3d/issues/423 ? Would you want to create a PR, adding this e.g. to the FAQ section on k3d.io?

Nay, I just wrangled my networking conf to get it working) It's not obvious why cluster initialization hangs but docker logs help quite a bit when you see that go's dial fails to resolve docker registry host. Even if each linux configuration tends to try to be unique additional entry in FAQ could do a bit of good. I'll think on it tomorrow
