Where does Microk8s keep kubelet.service?

Question

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?

Answer 1

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
