Traefik and the other services will not be able to see mysql because it's isolated to the compose default network and the ports are neither exposed nor forwarded and it's not on the web network which is how traefik routes it's traffic. Load balancer (Traefik) and ZEO instances connect via their own network (traefik-net). In this case only the web service can be seen by traefik and only port 80. "80" # I've got lots of services listening on 80, doesn't matter since it's a different veth Then you can declare services and you only need to expose the web service to traefik and not to the world, take Lychee for instance. "-Graylog-Server-URL="Īny suggestions would be greatly appreciated.In your compose you will export port 5000 in each of the nginx services. GRAYLOG_PASSWORD_SECRET:y98bRV3eKwYRFij8gEO9qROITGrJyzij3fJWWWqXDObkmCuFkJuPWeD0FlbRIxwkhcVFrhrnLt4cw1tri5I9bqcMeJOa43LL graylog_journal:/usr/share/graylog/data/journal Image: /elasticsearch/elasticsearch-oss:6.8.5 Traefik static config conf/traefik.yml entryPoints: "/var/run/docker.sock:/var/run/docker.sock"

"./conf/traefik.yml:/etc/traefik/traefik.yml" # Dummy service for Swarm port detection. Traefik docker compose file version: "3.7" Now create a new custom network named ‘proxy’ for the traefik container. Check the available docker network on the system. So we need to create a new docker custom network on the server. Since this is not only often a lot of work (especially if you have many services. This will work, but you need to remember to add the traefik instance to every docker container. Enable docker provider and web UI: traefik.yml Docker configuration backend providers: docker: defaultRule: Host(. You can also add the traefik instance to each and every docker network where a service container is located. dduportal I get your point, and again doesnt the setting label exists for traefik to connect to the specified network I mean, the docker api provides a way to connect a container to a network so this can be done, taking into account that traefik uses the docker api. You can create it with: docker network create -d overlay -attachable proxy In this tutorial, the traefik container will be running on the docker custom network. Alternate solution: Add traefik to every docker network. Traefik and Graylog communicate on external overlay network called proxy. Traefik defines some abstractions that are used to configure your network. By default, Traefik watches for container level labels on a standalone Docker Engine. This can be done in one command: docker network create -driveroverlay traefik-public.

You should be able to replicate this issue using my configuration on your local swarm. The first thing before creating the config file is to create a docker swarm network that will be used by Traefik to watch for services to expose.

Graylog works ok if I set GRAYLOG_HTTP_EXTERNAL_URI= and bypass Traefik. Better if it is the IP where the Traefik service runs (the manager node you are currently connected to).

to one of the IPs of the cluster. I’ve been trying to get Graylog 3 (in Docker Swarm) to run behind a reverse proxy, but I keep getting 502 Bad Gateway response. You will access the Traefik dashboard at traefik., e.g.
