Added new node to docker swarm, it looks good.
docker swarm join --token SWMTKN-1-1omic2el5jd3g98lm9x77o0px6ymauv3brjomfist1o2miga1x-c925hpkai0wm8pg5a01k2v9rv 192.168.100.174.222:2377
This node joined a swarm as a worker.
From UCP machine run: docker node list
I can see the new node STATUS is Ready, and AVAILABILITY is Active
However, at UCP Web UI, the new node Status is Down with the following message:
Unable to allocate the required ports for UCP, please visit https://www.docker.com/ddc-5 for more information.
How does this can be fixed? Does docker/ucp-agent proxy container have to be manually installed and run on the new node?
