@baptistebalmon Did you check if this is working correctly with v0.13.6? Can you attach the external-dns pod logs in Debug level?

Hi @leonardocaylent
I've tried to downgrade the externalDNS image version to v0.13.6.
The issue is still the same.
Kubernetes resources are deleted but DNS records are not.
Please find the log in debug mode.

Thank you for your help.

@baptistebalmon I can see that your plan is not detecting anything to delete. I need to ask you 3 more questions:
1)Has this ever worked for you before?
2)Can you test again with the versions v0.12.0 and v0.10.0?
3)If you manually delete the records external-dns creates them again on the next round?
If you can add the creation logs that could also help.
Thank you for reporting this issue

hi @leonardocaylent , thank you for helping me out on this.
It seems that externalDNS only creates (as we can see in the logs), I could never see UpdateOld, UpdateNew or Delete.
It explains why it recreates every entry but does not delete any.
Is it a normal behavior ?
-
I guess that the delete worked once first time that I installed externalDNS.
The only difference is that I didn't configure the annotation filter on the records to be managed by externalDNS.
I've tried to remove this configuration but it still doesn't work. -
I've tried with both v0.12.0 and v0.10.0 and I've got same result.
-
If I manually delete the records, they are created again on the next round.
Here are the logs of creation :

Hi again @leonardocaylent , problem solved
I've found that AXFR is mandatory to update or delete DNS records.
The TSIG key that I was using was only configured with DYNUPDATE.
I've added :
- AXFR on the TSIG key
- rfc2136-tsig-axfr flag to true on the externalDNS container
Updates and Deletes work now fine.
Thank you for the help.
