forked from Ivasoft/traefik
Using Docker provider, you can specify `traefik.frontend.rule` and `traefik.frontend.value` labels. If they are not both provided, there is a default behavior. On the current master, if they are not defined, the container is filtered (and thus the default behavior is broken). Fixes that. Signed-off-by: Vincent Demeester <vincent@sbr.pm>
