On a normal successful RKE2 install (on VMs, just KVM on CentOS rather than VMware) I get a helm-install-rke2-coredns-, helm-install-rke2-canal-, helm-install-rke2-ingress-nginx-, & helm-install-rke2-metrics-server- . That's held for v1.21 & v1.22, though the Rancher docs have a different list than I get so some older verison is somewhat different (though I think these were the same).
My understanding of the point of these is that things like kubelet, kube-apiserver, kube-proxy, kube-scheduler, kube-controller-manager, etcd (& maybe a few more I'm forgetting) get run as child processes to rke2-server service or as static pods with the RKE2 install. However, there are additional pieces to install to get things working, like the CNI, so those are installed to the fresh Kubernetes cluster (rather than static pods) with a helm job and that's what those are.
