Here’s what I did.
Installed UCP and DTR both on 3 nodes each for HA.
All was working fine.
Then I decided to “clean things up a bit” in (internal) DNS so registered user friendly aliases in DNS so the users would access UCP (or DTR) through something like “docker-ucp.company.com” rather than “server1531ab.strange.domain.com”.
All still fine.
Decided to update the “Load Balancer/Public Address” setting in DTR (Settings -> General -> Domain & proxies) but instead of DTR’s DNS friendly name I added the one that belongs to UCP. Then replaced it with DTR’s URL (the correct one).
Unfortunately when I check in UCP (Admin Settings -> Docker Trusted Registry) Installed DTRs lists:
- The old user-unfriendly DNS name
- UCP DNS name (entered accidently)
- DTR user-friendly name
I’d like to get rid of #1 and #2.
Any idea how?
