sudo snap install --classic microk8s
sudo microk8s enable dns:<dns_ip>

config files are at /var/snap/microk8s/current, and you need to replace all docker.io with some docker mirror to prevent init errors.

run microk8s inspect to get errors like hostname casing, and missing file like /var/snap/microk8s/current/var/kubernetes/backend/localnode.yaml

you need to configure multiple registries for docker.io and registry.k8s.io under /var/snap/microk8s/current/args/certs.d

in order to use some mirror site which does not support /v2 url, you have to add override_path = true in config
