I see k3s is up and running:

Don't think the following errors are related:

Maybe you have an idea @AkihiroSuda?

Looks better now, thanks @AkihiroSuda! I'm looking at the tests failure https://github.com/crazy-max/buildx/actions/runs/7624605445/job/20767159528#step:6:54

Most likely linked to the local registry that can't be accessed from the node as it runs from the host.

Is it a bug in k3s that generates a wrong containerd config?

Edit: Ok seems it's because containerd shipped with docker is currently 1.7.
