Hi, i would love to deploy strapi with docker-compose behind Traefik. I want to make run 2 strapi with differents path like this : - http://localhost/test
- http://localhost/prod
For this i saw that i have to use serve.js, so i did this :

module.exports = ({ env }) => ({
  host: env('HOST', '0.0.0.0'),
  port: env.int('PORT', 1337),
  url: '/test',
  proxy: true,
  admin: {
    auth: {
      secret: env('ADMIN_JWT_SECRET', '7b2e0c412e0e5c95787e9d469eecb35b'),
    },
  },
});

docker-compose :

version: "3"

services:
  strapi-test:
    container_name: strapi-test
    image: strapi/strapi
    restart: unless-stopped
    environment:
      DATABASE_CLIENT: ${DATABASE_CLIENT}
      DATABASE_NAME: ${DATABASE_NAME}
      DATABASE_HOST: ${DATABASE_HOST}
      DATABASE_PORT: ${DATABASE_PORT}
      DATABASE_USERNAME: ${DATABASE_USERNAME}
      DATABASE_PASSWORD: ${DATABASE_PASSWORD}
    labels:
      traefik.enable: true
      traefik.http.routers.strapi-dev.entrypoints: web
      traefik.http.routers.strapi-dev.rule: PathPrefix(`/test`)
    volumes:
      - ./strapiTest:/srv/app
    ports:
      - "1337:1337"
    networks:
      - strapi-test

  postgres:
    image: postgres
    container_name: postgres-test
    environment:
      POSTGRES_DB: ${POSTGRES_DB}
      POSTGRES_USER: ${POSTGRES_USER}
      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
    volumes:
      - ./dbTest:/var/lib/postgresql/data
    networks:
      - strapi-test

networks:
  strapi-test:
    external: true

When i run localhost:1337/dev i get “debug GET /test (3 ms) 404” in my strapi container
When i try to access with traefik localhost/dev i get the same “debug GET /test (3 ms) 404”
I saw that i have to use a proxy because url wont work without but i am not
comfortable with all this notions. Should i put nginx between traefik and strapi ? Or something else ?
