Possible to listen to both www.example.com and example.com?

[polds]

Using the wildcard subdomain you can listen to {subdomain: [a-z]+}.example.com, that however does not also include example.com. Is it possible to listen to both?

[emilevauge]

@polds, you can add another frontend with Host : example.com, it should work. Can you confirm ?

I'm also having trouble setting this up. I have a backend defined:

[backends.mysite]
  [backends.mysite.servers.server1]
  url = "http://127.0.0.1:81"

Now I want this backend to be accessable through both mysite.nl and www.mysite.nl. I tried to do this:

[frontends.mysite]
backend = "mysite"
passHostHeader = true
  [frontends.mysite.routes.host1]
  rule = "Host"
  value = "www.mysite.nl"
  [frontends.mysite.routes.host2]
  rule = "Host"
  value = "mysite.nl"

Unfortunately this does not work, both mysite.nl and www.mysite.nl is resolving in HTTP/1.1 404 Not Found. When I remove the 2nd frontend, the first one will work again.

@emilevauge Sorry I should have mentioned I'm using the Docker provider so not dealing with frontends.

Hi @polds @rogierlommers, it's seems to be a bug :( Will look at it.

[hd-deman]

same bug with consul provider and file provider.

[hd-deman]

this is absolutely crazy to create new frontend for each rote, instead of creating routes for one frontend.

[emilevauge]

And this kind of comment makes me wonder why this project is open source and free to use...

[hd-deman]

I feel your pain.

I just tested it using docker backend, and it seems to work (on the latest version):

$ docker run -d -l traefik.backend=test -l traefik.frontend.rule=Host -l traefik.frontend.value=docker.localhost emilevauge/whoami
$ docker run -d -l traefik.backend=test -l traefik.frontend.rule=Host -l traefik.frontend.value=test.docker.localhost emilevauge/whoami

$ curl -s http://localhost:8080/api/providers | jq .

Using file backend with these rules seems also OK:

  [backends]
    [backends.backend1]
      [backends.backend1.LoadBalancer]
        method = "wrr"
      [backends.backend1.servers.server1]
      url = "http://172.17.0.2:80"
      weight = 1

  [frontends]
    [frontends.frontend1]
    backend = "backend1"
      [frontends.frontend1.routes.test_1]
      rule = "Host"
      value = "localhost"
    [frontends.frontend2]
    backend = "backend1"
      [frontends.frontend2.routes.test_1]
      rule = "Host"
      value = "{subdomain:[a-z]+}.localhost"

Could you give more info on your conf? Could you test using my exemple?

I know that using multiple frontends to do that is not perfect, but for now, this is a workaround. I'm planning to modify the behavior of routes, now there is a AND operation between routes from a frontend, and I think it would be more useful to have a OR. WDYT?

[hd-deman]

@emilevauge you example works because you define two frontends:

  [frontends]
    [frontends.frontend1]
    backend = "backend1"
      [frontends.frontend1.routes.test_1]
      rule = "Host"
      value = "localhost"
    [frontends.frontend2]
    backend = "backend1"
      [frontends.frontend2.routes.test_1]
      rule = "Host"
      value = "{subdomain:[a-z]+}.localhost"

But If you define one frontend and two routes for it, it doesn't:

  [frontends]
    [frontends.frontend1]
    backend = "backend1"
      [frontends.frontend1.routes.test_1]
      rule = "Host"
      value = "localhost"
      [frontends.frontend2.routes.test_2]
      rule = "Host"
      value = "{subdomain:[a-z]+}.localhost"

[emilevauge]

@hd-deman, that's why I said:

[emilevauge]

@polds, is the issue still there? Because I cannot reproduce it here ;)

[polds]

Yeah if launched twice it works with no issues :)
