General

I Want to dockerizing my strapi app but have some problem like this image
image

I Already set the url in ./config/admin.js

module.exports = ({ env }) => ({
  auth: {
    secret: env('ADMIN_JWT_SECRET', 'ac0b654fce47e425cab20649bb95a2fa'),
  },
  url:"http://localhost:8004/admin"
});

and my ./config/server.js

module.exports = ({ env }) => ({
  host: env('HOST', '0.0.0.0'),
  port: env.int('PORT', 1337),
  app: {
    keys: env.array('APP_KEYS'),
  },
  url:"http://localhost:8004/"
});

my docker-compose.yml

services:
  app-staging:
    build: 
      context: .
    container_name: api-strapi-dev
    env_file: .env
    ports: 
      - "8004:1337"
    networks: 
      - strapi
    restart: always
