Due to the nature of dynamic routing in Traefik you may get stuck with unexpected
problems with Bad gateway. It can happen because of launched engineering container.
Suppose this situation: You started rails server container (1) which supposed serve requests
and you started another rails console (2) container with console. Now Traefik may route web
requests to (2) container where is the web server didn't run. To avoid this problems
you should run container with traefik.enable=false label.
Ex. docker-compose run -l "traefik.enable=false" --rm rails ./bin/rails c
