Where does Microk8s keep kubelet.service?

I am trying to enable a FlexVolume driver on Microk8s on Ubuntu.

To do that, it seems I have to edit the kubelet.service file. This is supposed to be stored in /etc/systemd/system/kubelet.service but it is't present in my installation.

Where is it stored for Microk8s? Surely it has kubelet running somewhere?

Solution

The microk8s kubelet service is present at the following location:

/etc/systemd/system/snap.microk8s.daemon-kubelet.service

You can always check that using the service daemon:

systemctl status snap.microk8s.daemon-kubelet

A little bit more information, to check what is running by microk8s, you can use:

velotio@velotio-ThinkPad-E470:~$ microk8s.inspect
