Symfony 5 - Use different host for environment (dev, prod) - php

Question

in my Symfony 5 project, I am looking to use different subdomains for my controllers depending on the environment I am in (dev, prod).
For this, I created:
config/routes/dev/annotations.yaml
and
config/routes/prod/annotations.yaml
Each file contains its own host for my controllers.
config/routes/dev/annotations.yaml:
blog_controllers:
resource: ../../../src/Controller/BlogController.php
type: annotation
host: 'blog.{domain}'
defaults:
domain: '%domain%'
requirements:
domain: '%domain%'
app_controllers:
resource: ../../../src/Controller/HomeController.php
type: annotation
host: 'app.{domain}'
defaults:
domain: '%domain%'
requirements:
domain: '%domain%|www.%domain%'
config/routes/prod/annotations.yaml:
blog_controllers:
resource: ../../../src/Controller/BlogController.php
type: annotation
host: 'prod.blog.{domain}'
defaults:
domain: '%domain%'
requirements:
domain: '%domain%'
The %domain% is the APP_DOMAIN in my .env, no problem with that.
So, when I'm on prod environment, when I'm trying to access https://prod.blog.[myDomain] (the homepage on my blog project part), I'm redirected on the homepage of the HomeController. I don't know why...
My controllers :
BlogController.php:
class BlogController extends AbstractController
{
/**
* #Route("/", name="blog")
*/
public function index()
{
return $this->render('blog/index.html.twig');
}
}
HomeController.php:
class HomeController extends AbstractController
{
/**
* #Route("/", name="home")
*/
public function index()
{
return $this->render('home/index.html.twig');
}
}
edit:
I tested with this configuration :
Just in prod, set this route in the /config/prod/annotations.yaml
blog_controllers:
resource: ../../../src/Controller/BlogController.php
type: annotation
host: 'blog.{domain}'
defaults:
domain: '%domain%'
requirements:
domain: '%domain%'
No host for dev environment.
So, on prod environment, if I make a debug:router, I've :

So both routes here are correct.
On the one hand, the "home" route without a subdomain, accessible by http s://myDomain.com
and on the other, the "blog" route accessible by http s://blog.myDomain.com
Are we OK?
But when I launch http://blog.myDomain.com/, It's the Home controller which is displayed !
EDIT 2 : Okay I found the solution.
Just add host for "home" route, like this :
app_controllers:
resource: ../../../src/Controller/HomeController.php
type: annotation
host: '{domain}'
defaults:
domain: '%domain%'
requirements:
domain: '%domain%|www.%domain%'
No subdomain. It works.
Thanks all !
