Adding docker labels traefik.<servicename>.* properties like
- traefik.mycustomservice.port=443 - traefik.mycustomservice.frontend.rule=Path:/mycustomservice - traefik.anothercustomservice.port=8080 - traefik.anothercustomservice.frontend.rule=Path:/anotherservice all traffic to frontend /mycustomservice is redirected to the port 443 of the container while using /anotherservice will redirect to the port 8080 of the docker container More documentation in the docs/toml.md file Change-Id: Ifaa3bb00ef0a0f38aa189e0ca1586fde8c5ed862 Signed-off-by: Florent BENOIT <fbenoit@codenvy.com>
