An /etc/default/kubelet file to quickly configure kubelet variables to use CRI-O with kubeadm

cri-o-kubeadm

KUBELET_EXTRA_ARGS=--feature-gates="AllAlpha=false,RunAsGroup=true" --container-runtime=remote --cgroup-driver=systemd --container-runtime-endpoint='unix:///var/run/crio/crio.sock' --runtime-request-timeout=5m

May be usefull:
Kubelet from scratch config using by systemd /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

[Service]
Environment="KUBELET_KUBECONFIG_ARGS=--bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf
--kubeconfig=/etc/kubernetes/kubelet.conf"
Environment="KUBELET_CONFIG_ARGS=--config=/var/lib/kubelet/config.yaml"

This is a file that "kubeadm init" and "kubeadm join" generate at runtime, populating

the KUBELET_KUBEADM_ARGS variable dynamically
EnvironmentFile=-/var/lib/kubelet/kubeadm-flags.env

This is a file that the user can use for overrides of the kubelet args as a last resort. Preferably,

the user should use the .NodeRegistration.KubeletExtraArgs object in the configuration files instead.

KUBELET_EXTRA_ARGS should be sourced from this file.

EnvironmentFile=-/etc/default/kubelet
ExecStart=
ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_CONFIG_ARGS $KUBELET_KUBEADM_ARGS $KUBELET_EXTRA_ARGS

thanks for your comment @Kali-lightsaber, i think I'm going to update the documentation to use the script i created here cri-o/cri-o#4393 (comment) with native kubeadm config print..., instead of putting files in different places
