How can i configure Internal Host for Applications?

[joetifa2003]

I saw in the docs that I can specify an internal host/port to connect to the database.

How can I do the same thing for Applications?

For example, if I have a service that I don't want to expose to the public, but I want other services to see it, how can I connect them?

Is it by the App name field when I create the service, when I tried to create services with an existing app name, it didn't error out, so this cannot be possible.

And when I open a service I see, which I guess, is the container name like this foo-9asdas...

Can i connect to the service by using host https://foo-9asdas:<PORT>

I think this should be added to the docs.

By default every application/database comes with a hostname which is next to the name of the application usually is something like
projectName-applicationName-${HASH}

This is what we do to for domain mapping

Thank you!

I did try to do a curl from the container terminal and it seems to be working (same port as the domain), I didn't need to do any configuration change.

So by default i can access any port in the container, without publish/exposing the ports to the public?

Also, can you point to me some doc related to this?

@Siumauricio Hello!

We've created a service using Dockerfile (branch deploy) and configured a Traefik domain, and the configuration in the advanced tab was generated correctly. However, it's not working (just getting a 404 error). Is there any additional configuration needed in this case?

Here's the generated YAML:

# fake values
http:
  routers:
    test-router:
      rule: >-
        Host(`test-domain.traefik.me`)
      service: test-service
      middlewares: []
      entryPoints:
        - web
  services:
    test-service:
      loadBalancer:
        servers:
          - url: http://test-host:3000
        passHostHeader: true

Additionally, we've created a domain using an A record in DNS, but it still doesn't work. (Using docker-compose services works perfectly with "labels" configuration)

Thanks in advance

After some traefik restart in webserver session the mapping now works!

I have the same question. After deploy an application, I checked the Trafik setting in the advanced panel.
However it shows No traefik config detected.

Do I have to set up a domain for it to work?

@auroradanier In addition to the Traefik settings, did you configure or generate the Traefik domain in the application settings?

Once the domain is created, you can test if it routes to the correct place.

No, I didn't create domain because I don't want it to expose to the public.
I see what's happening, must set some domain. Even it's a fake one.
Then I can see the Traefik config in the advanced panel.
That's kinda hidden.
