Docker - Symfony5/Mercure : Impossible to reach mercure hub - docker

Question

I try with no success to access to Mercure's hub through my browser at this URL :
http://locahost:3000 => ERR_CONNECTION_REFUSED
I use Docker for my development. Here's my docker-compose.yml :
# docker/docker-compose.yml
version: '3'
services:
database:
container_name: test_db
build:
context: ./database
environment:
- MYSQL_DATABASE=${DATABASE_NAME}
- MYSQL_USER=${DATABASE_USER}
- MYSQL_PASSWORD=${DATABASE_PASSWORD}
- MYSQL_ROOT_PASSWORD=${DATABASE_ROOT_PASSWORD}
ports:
- "3309:3306"
volumes:
- ./database/init.sql:/docker-entrypoint-initdb.d/init.sql
- ./database/data:/var/lib/mysql
php-fpm:
container_name: test_php
build:
context: ./php-fpm
depends_on:
- database
environment:
- APP_ENV=${APP_ENV}
- APP_SECRET=${APP_SECRET}
- DATABASE_URL=mysql://${DATABASE_USER}:${DATABASE_PASSWORD}#database:3306/${DATABASE_NAME}?serverVersion=5.7
volumes:
- ./src:/var/www
nginx:
container_name: test_nginx
build:
context: ./nginx
volumes:
- ./src:/var/www
- ./nginx/nginx.conf:/etc/nginx/nginx.conf
- ./nginx/sites/:/etc/nginx/sites-available
- ./nginx/conf.d/:/etc/nginx/conf.d
- ./logs:/var/log
depends_on:
- php-fpm
ports:
- "8095:80"
caddy:
container_name: test_mercure
image: dunglas/mercure
restart: unless-stopped
environment:
MERCURE_PUBLISHER_JWT_KEY: '!ChangeMe!'
MERCURE_SUBSCRIBER_JWT_KEY: '!ChangeMe!'
PUBLISH_URL: '${MERCURE_PUBLISH_URL}'
JWT_KEY: '${MERCURE_JWT_KEY}'
ALLOW_ANONYMOUS: '${MERCURE_ALLOW_ANONYMOUS}'
CORS_ALLOWED_ORIGINS: '${MERCURE_CORS_ALLOWED_ORIGINS}'
PUBLISH_ALLOWED_ORIGINS: '${MERCURE_PUBLISH_ALLOWED_ORIGINS}'
ports:
- "3000:80"
I have executed successfully :
docker-compose up -d
docker ps -a :
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

I can reach http://localhost:8095 to access to my Symfony app but I don't know on which URL I am supposed to reach my Mercure's hub.
Thank's for your help !

I tried for months to get symfony + nginx + mysql + phpmyadmin + mercure + docker to work both locally for development and in production (obviously). To no avail.
And, while this isn't directly answering your question. The only way I can contribute is with an "answer", as I don't have enough reputation to only comment, or I would have done that.
If you're not tied to nginx for any reason besides a means of a web server, and can replace it with caddy, I have a repo that is symfony + caddy + mysql + phpmyadmin + mercure + docker that works with SSL both locally and in production.
