traefik + ssl everywhere + swarm mode + docker-compose.yml

[jagbarcelo]

I've been following your step-by-step instructions on how to install traefik + portainer through Put Wildcard Certificates and SSL on EVERYTHING and also your related video https://www.youtube.com/watch?v=liV3c9m_OX8

Everything went fine but now I'm struggling to make it work after having created a Swarm with 3 Raspberry Pi's: I want traefik to work as proxy for containers running on any node of the swarm/cluster.

According to Traefik documentation, for it to work in a Swarm, it must be deployed on a master node (no problem since my 3 nodes are managers). Thus, I included this in the docker-compose.yml:

    deploy:
      #mode: global     #Should it be installed on every manager node or will it suffice with just one?
      placement:
        constraints:
          - node.role == manager

I've also created a new overlay network (instead of the regular bridge mode network you used, called proxy) and modify the docker-compose accordingly.

Besides, it seems that the labels must be nested one level deeper, under the deploy tag, thus:

[...]
    deploy:
      placement:
        constraints:
          - node.role == manager
      labels:
        - traefik.enable=true
        - traefik.docker.network=proxy-overlay
        [more labels here]
networks:
  proxy-overlay:
    external: true

I've also modified the data/traefiik.yml file to include:

providers:
  docker:
    swarmMode: true
    endpoint: "unix:///var/run/docker.sock"
    watch: true
    exposedByDefault: false

I'm using your file as template, tried every possible combination but I still cannot make it work:

Everytime, every possible change that has come to my mind leads me to a 404 File not found error page when the docker-compose file is deployed.

Can you shed some light on what changes would be needed in your template to make it work on a swarm mode cluster?

Thank you.
