Hi @losif, if the 2 TCP "backend services" are served outside Docker, using the file provider would be the way to go.
- Enabling File provider: You figured out correctly the flag of the Traefik CLI configuration:
--providers.file.filename=rules.ymlenables the provider "File" and set it up to get its configuration from the file located on./rules.yml - Providing the file
rules.ymlto the Traefik container: did you notice that I used a dot-slach (./) for the location ofrules.yml? Because the value you've set for the flagproviders.file.filenameis a relative path INSIDE the Traefik container. You have to share this file between your machine and the traefik container, by mounting it on a specified path, as you did with v1.7 with thetraefik.toml. My recommendation for you:- Mount the file with docker-compose by adding the item
- ./rules.yml:/rules.ymlin the directivevolumes:of the docker-compose "service" Traefik (https://gist.github.com/IosifZ/f85ce274e02692bea100aa0f75e422e9#file-docker-compose-yml-L38). - Set the CLI flag
--providers.file.filenameto the value/rules.yml
- Mount the file with docker-compose by adding the item
