[Bug 1852599] [NEW] Cannot delete TLS Terminated listener if container has been deleted in barbican

Launchpad Bug Tracker 1852599 at bugs.launchpad.net
Wed Jan 8 04:25:10 UTC 2020 

You have been subscribed to a public bug by Ubuntu Foundations Team Bug Bot (crichton):

There seems to be a fault condition in amphora builds that can lead to
not being able to delete a failed loadbalancer/listener.

If the barbican container for a tls terminated endpoint listener is
deleted before the listener/amphora is deleted, the query to update to
the listener's tls certificates fails during the delete_pools flow.

It exhibits the following in the client:

DELETE call to None for https://octavia.mysite:9876/v2.0/lbaas/listeners/4f46a6a3-a756-41b2-9148-c060bf28e621 used request id req-8146cc8c-334a-4155-9fa6-489d4cf1ecbf
