I just land on k3s two days ago. got some question when deploy k3s on my odroid xu4(arm32) sbc. The k3s is running with

k3s server --config /etc/rancher/k3s/config.yaml

right now. but `kubectl get pods -n kube-system`show nothing about flannel, servicelb, traefik. The docs says:

There are two major ways that K3s is lighter weight than upstream Kubernetes:

The memory footprint to run it is smaller
The binary, which contains all the non-containerized components needed to run a cluster, is smaller
The memory footprint is reduced primarily by running many components inside of a single process. This eliminates significant overhead that would otherwise be duplicated for each component.
