I unfortunately haven't tested this with 1.20 yet. These log entries aren't necessarily a sign of problem though. Do you have any other issues, or a more complete log?

[ghorofamike]

i get no other logs, iv been looking thru the code, and im not seeing any of the log lines i would expect, it literary prints only those lines. so something changed somewhere and its not getting events or so, and no normal execution paths happen that trigger logging. what are your suggestions?

[ghorofamike]

So theres is some operator error involved, i cant tell where, i had not requested debug logs, here they are after changing configs:
Here is a link to the whole logs: fpaste, and here is a snippet:

Does it mean its the interaction with metallb thats problematic? it seems to see that any of my IP's are attached.

[costela]

Yes, this looks like it could be a metallb issue. What does kubectl get svc say? Is k8s getting IPs from metallb?

And what version of hcloud-ip-floater are you using?

[ghorofamike]

I think i have it resolved, its like most issues, operator error, i mixed up my service "selector", (reversed some hyphenated words). so false alarm. without the selectors, this tool could not see live pods for the service, so it would not attach the ips. its easily confused to be a metallb issue, but its not.
