This image is the traefik dynamic conf for rancher. It comes from rawmind/rancher-tools.

docker build -t rawmind/rancher-traefik:<version> .

• 1.5.0-0 (Dockerfile)
• 1.4.4-6 (Dockerfile)
• 1.3.6 (Dockerfile)
• 1.3.3-2 (Dockerfile)
• 0.3.4-19 (Dockerfile)

This image has to be run as a sidekick of rawmind/alpine-traefik, and makes available /opt/tools volume. It scans from rancher-metadata, looking for services and externalServices that have traefik labels and generates traefik frontend and backends to expose the services.

Traefik labels have to be created in your service or externalService in order to get included in traefik dynamic config.
