Traefik not finding dynamically added services (Docker Swarm Mode)

[austinfrey]

What version of Traefik are you using (traefik version)?

Version: v1.1.2
Codename: camembert
Go version: go1.7.4
Built: 2016-12-15_10:21:15AM
OS/Arch: linux/amd64

What is your environment & configuration (arguments, toml...)?

currently launching as part of a docker stack deploy command

traefik:
    image: traefik:latest
    command: -c --docker=true --docker.swarmmode=true --docker.domain=traefik --docker.watch =true --web=true --debug=true
    ports:
      - 80:80
      - 8080:8080
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
    networks:
      - traefik-net
    deploy:
      placement:
        constraints: [node.role == manager]

What did you do?

launched Traefik via docker stack deploy I have another service that will create new services and attaches them to the traefik network. They have traefik.port and traefik.frontend.rule labels. I also created a service with the same labels via the docker CLI

What did you expect to see?

I should be able to interact with this new service via traefik.

What did you see instead?

Currently I can not interact with the service. I CAN interact with services with the same apparent setup when created via docker CLI

Debug log showing test1 service is recongnized by traefik but no IP is attached. This service was created using docker-py from another service, and test2 the service created by docker CLI

Any help is appreciated. Thanks!

this was solved by passing endpoint_spec={'Mode': 'vip'} as a parameter in the client.services.create() call. so this was a docker-py issue not a traefik issue. sweet relief....

We are expiriencing same issues with traefik:v1.2.0-rc2, since traefik dynamic configuration is not updated when new service is deployed to swarm.

Using:

• Ubuntu 16.04.1 LTS
• docker-py==1.10.6
• docker-engine 1.13.1-0~ubuntu-xenial

This was working fine with traefik:6c92697 with the same version of docker-engine and docker-py.
