How should I run a multicontainer app/platform with nginx behind traefik? I have Traefik reverse proxy running to allow a couple of docker containerized apps to run on the same domain just to learn about running multiple containers following https://www.smarthomebeginner.com/traefik-reverse-proxy-tutorial-for-docker. Everything works well.  I want to install Device Hive to test it as an IOT platform, but it has multiple containers and it's own nginx proxy and docker-compose file https://github.com/devicehive/devicehive-docker/blob/master/rdbms-image/docker-compose.yml.

Is there a way I can add the Device Hive platform to my existing Traefik build or is it more trouble than its worth.  I wondering, more or less while making sure I'm not having a port conflict, if there's an easy way to have Traefik point a subdomain(subdomains are used for the other apps) to the 80/443 ports of the nginx proxy, and just have everything work.  My other option is to create another VM for the IOT platform. 

I may be searching with the wrong terms but I haven't really found an answer. Any help?

Note: I want to use Device Hive on my existing server which is using Traefik. When I look at the docker compose file for Device Hive I don't see how I could change it to leave Nginx out.
Although I agree with @BruceBecker's comment, i.e. running two different rproxies, it is possible to run traefik in front of nginx. At the previous job we configured several servers that were running on nginx behind traefik.

Ensure that each microservice has the correct labels. Note that Traefik 2.0 changed significantly.
