1. K3s is running in docker, but you have not mounted the docker socket into the container so it cannot connect to it.
2. registries.yaml only works with the bundled containerd, not with docker.

i add this,why create so many?
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- /var/run/cri-dockerd.sock:/var/run/cri-dockerd.sock
- /var/lib/docker:/var/lib/docker
