Because NGINX only resolves hostnames at startup and the IP addresses assigned to Docker containers are not fixed, we sometimes have this condition:
…which leads to this kind of nastiness:
[x] Make failures obvious by moving KoBoCAT to port 8001 (instead of 8000, which is used by KPI)
These are internal, Docker-only ports that should not conflict with other services running on the host; this should be obvious given that even two containers exposing the same port does not cause a conflict;
Eh, it looks like we would need to hard-code resolver 127.0.0.11, which supposedly will never change, but isn't something I can find in the official documentation. I'm not sure that would really be an improvement.

See if we can get NGINX to re-resolve hostnames after starting, without needing an NGINX Plus license: https://www.nginx.com/blog/dns-service-discovery-nginx-plus/resolver 127.0.0.11, which supposedly will never change, but isn't something I can find in the official documentation.
