This is expected due to the way the hostname/IPs are managed. This reuses the code that we use in the overcloud and the reason why they are the same is because we don't actually have different IPs for the various "networks". This is currently how it works and unless it's breaking something this is NOTABUG. Hi Alex, When we did the initial deployment of overcloud, this entry was not seen. After stack update, three of such entries were added: Here are the concerns: 1. Why are there duplicate entries of the same IP seen as above? 2. The above entry also looks like it has a lot of repetition, for example - 'undercloud.ctlplane' itself is repeated 15 times in a single line. 3. At every stack update these line almost increase by 3 times. For example: Before: 172.16.0.1 undercloud.ctlplane.localdomain undercloud.ctlplane undercloud undercloud.external.localdomain undercloud.external undercloud.ctlplane.localdomain undercloud.ctlplane

Ok that's a bug where we're continuing to re-add hosts for every deployment. I think that's been fixed but we'll have to dig up the fix and see where it's landed. I've renamed the bug to more closely describe the issue. *** Bug 1855172 has been marked as a duplicate of this bug. *** *** Bug 1873107 has been marked as a duplicate of this bug. *** *** Bug 1879931 has been marked as a duplicate of this bug. *** According to our records, this should be resolved by python-tripleoclient-12.3.2-1.20200914164928.el8ost.
