Traefik and other auto discovery systems registers same service twice because it appears twice with its own internal ip and ip of the node. In single node settings, it causes a problem.

Hey @colcek — this PR inspired the -ip-from-container flag implemented in https://github.com/fayrus/registrator. The behavior matches exactly what you described: when the flag is set, the container's internal IP is used for service registration instead of the host IP, which prevents duplicate registrations with Traefik and similar systems. Credit is noted in the changelog. Thanks for the contribution here — it's a real-world fix that deserved to land somewhere.
