Hi, rlaveycal …
If I may ask, is your DDC’s UCP setup in HA, running on RHEL 7.3 with Overlay storage driver?
My current DDC cluster setup is on RHEL 7.3 64bit, and I have even switched to Docker Enterprise Engine 17.03.0-ee-1 with storage driver set to the default “Overlay”. Again, this is with the three UCP node managers on version 2.1.1 and three DTR nodes on version 2.2.3.
And yet, the “unhealthy UCP controller” still shows.
It works okay and no unhealthy error, if I only have one UCP node manager.
