I am not able to eliminate the Port information from the URLs

Hi all.

My DNS A record is ws-traefik.wslan and it is pointing to the IP of the VM where traefik is running .

My docker-compose is

version: '3.2'
      name: ntwkr_docker

    image: traefik:v2.6
    command: --api.insecure=true --providers.docker
    container_name: wstraefik
    restart: unless-stopped
      - netdocker
      - 80:80
      - 8080:8080
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - traefik.enable=true
      - traefik.http.services.wstraefik.loadbalancer.server.port=8080
      - traefik.http.routers.wstraefik.entrypoints=http
      - traefik.http.routers.wstraefik.rule=Host(`ws-traefik.wslan`) && PathPrefix(`/wstraefik`)

When I enter with http://ws-traefik/wstraefik I get the error
404 page not found

On the other hand when I enter with http://ws-traefik:8080/ (without the prefix) the traefik dashboard appears

What is wrong with the service configuration?

Hello @marcos.nobre,

There is a guide in the traefik documentation if you want to expose the dashboard through traefik.

Here, it seems that you have a missmatch between your rule Host(`ws-traefik.wslan`) && PathPrefix(`/wstraefik`) and the URL you requested http://ws-traefik/wstraefik. You should have requested ws-traefik.wslan/wstraefik.

Hope it helps

Here is an example of a working use case :

version: '3.8'

    image: traefik:v2.6
      - --providers.docker
      - --api.dashboard=true
      - --entrypoints.web.address=:80
      - "80:80"
      - /var/run/docker.sock:/var/run/docker.sock
      traefik.http.routers.dashboard.rule: Host(`traefik.localhost`) && (PathPrefix(`/api`) || PathPrefix(`/dashboard`))
      traefik.http.routers.dashboard.entrypoints: web
      traefik.http.routers.dashboard.service: api@internal

Note that this example can be a security risk if you run it without protection in a production environment(e.g. basic auth).

Hi Tommoulard.

First of all, I thank you for your attention.

Regarding my misspelled post, I inform you that the url I am sending is http://ws-traefik.wslan/wstraefik and even then the error "404 page not found" continues to occur.

however when I inform http://ws-traefik.wslan:8080/ , the url is changed to http://ws-traefik.wslan:8080/dashboard/#/ and the dashboard appears.

I'll try your suggestion of docker-compose, but I have the following doubt:

What does the word web that appears in your configuration mean?
traefik.http.routers.dashboard.entrypoints: web
A traefik verb ? A name ? An alias ?



Another question is:

In my case what should i exchange for .....( traefik.localhost ) ?

And which url should I call to run the dashboard?


Would it be this ?

As stated in the documentation, doing --entrypoints.web.address=:80 defines an entrypoint called web that will listen on port 80. So here, web is just a custom entrypoint name(e.g. it could have been web-custom).
This name is used to reference the entrypoint when we need it.
Here for example:

      traefik.http.routers.dashboard.entrypoints: web

Here, you can change this to your host of choice, i.e. ws-traefik.wslan for your use case.

For my example, you will be able to find the dashboard on http://traefik.localhost/dashboard/.
