You can move this under the typePod case because you output only if HostIP is not empty --- here: https://github.com/netobserv/flowlogs-pipeline/pull/196/files#diff-77b720060ce5b2e61d001e832eac1bf4d94ffdeb9734bbd4ee678d9398ad3892R155

And this is set only for pods

[jpinsonneau]

Yes I was wondering if we could do the same for services but it can run on multiple pods / hosts and we'll need to manage arrays.

Let's keep it simple for now, thanks for the feedback 👍
