When a pod is configured with "hostNetwork: true", the applications
running in such a pod can directly see the network interfaces of the
host machine where the pod was started. From the networking point of
view, it will behave as any other application running in the host.
And, even if flannel is still running in the host, the pod will not
be automatically connected to that overlay network but use the
native routing mechanism.<br>
<br>

You can still tell kubernetes to create a pod that uses the
host network:<br>
<br>
kind: Pod<br>
spec:<br>
hostNetwork: True<br>
...<br>
<br>
However please evaluate whether that makes still sense in
the kubernetes<br>
context.<br>
<br>
Cheers<br>
Flavio<br>
