Too many DTRs in UCP


(Jacekdomanskigsk) #1

Hi,
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:

  1. The old user-unfriendly DNS name
  2. UCP DNS name (entered accidently)
  3. DTR user-friendly name
    I’d like to get rid of #1 and #2.
    Any idea how?

Did you ever figure out how to do this?

It worked!
Thank you.

I used http://success.docker.com/article/Multiple_DTRs_shown_on_UCP_2.2_when_only_one_or_none_exists on my UCP 2.2.3 and things got sorted out smoothly.
