Problem with setting up Traefik Middleware

[Cloufish]

I struggle with setting up Sablier Middleware in Traefik.

I use Docker Swarm + Traefik
Probably the culprit lies in traefik-conf.yml
Should I define middleware on top of entrypoint: http:?
There are a lot of configuration examples in Discussion, but I wanted to stick to the website documentation

web-app docker-compose:

version: '3'

services:
  rust-book:
    container_name: rust-book

      - PGID=1000
      - TZ=Europe/Warsaw
    deploy:

        - "traefik.enable=true"
        - "traefik.http.routers.rust-book.rule=Host(`rust-book.home`)"

Hello @Cloufish !

You were very close of acheiving what you wanted!

it looks like you're just missing the actual middleware on your route.

While looking at the current documentation I can understand why it's confusing, the documentation is not showing the whole configuration.

I will fix that soon.

In the meantime, you can always check e2e tests that are located on the folder e2e of each plugin.

For traefik it will be plugins/traefik/e2e/<provider> (in your case docker_swarm).

See: https://github.com/acouvreur/sablier/tree/main/plugins/traefik/e2e/docker_swarm

---

Now to the solution:

Because you've setup you're middleware from the file provider, you can add the following deploy label to your service:

services:
  rust-book:
    container_name: rust-book
    image: peaceiris/mdbook:v0.4.28
    stdin_open: true
    tty: true
    ports:
      - "80"
    networks:
      - web
      - rust-book
    volumes:
      - /home/swarm/books/rust-book:/book
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/Warsaw
    deploy:
      labels:
        - "traefik.enable=true"
        - "traefik.http.routers.rust-book.rule=Host(`rust-book.home`)"
+       - "traefik.http.routers.rust-book.middlewares=my-sablier@file"
        - "traefik.http.services.rust-book.loadbalancer.server.port=3000"
        - "traefik.docker.network=web"
        - "io.portainer.accesscontrol.users=admin"
        - "traefik.http.routers.rust-book.tls=true"
        - "sablier.enable=true"    # I ADDED THIS
        - "sablier.group=non-essential"    # I ADDED THIS
        - "traefik.docker.lbswarm=true"    # I ADDED THIS
    command:
      - serve
      - --hostname
      - '0.0.0.0'

The line

"traefik.http.routers.rust-book.middlewares=my-sablier@file

Will let know traefik to attach the middleware to your service. Once attached, if the middleware is properly configured, you should have a request issued to sablier before reaching your service!

Let me know if that works.
