docker-compose sail network

I'm using Laravel Sail, and this is my Docker Compose file. I need to connect Laravel to an external network, but I want the database to be accessible only within the container for the Laravel application because my local ports for the PostgreSQL database are conflicting. When I build and run this with sail artisan migrate, I get an error stating that it cannot connect to the database.

services:
  laravel.test:
    build:
      dockerfile: Dockerfile
      args:
        WWWGROUP: '${WWWGROUP}'
    image: sail-8.3/app
    extra_hosts:
      - 'host.docker.internal:host-gateway'
    ports:
      - '${APP_PORT:-80}:80'
      - '${VITE_PORT:-5173}:${VITE_PORT:-5173}'

      POSTGRES_USER: '${DB_USERNAME}'
      POSTGRES_PASSWORD: '${DB_PASSWORD:-secret}'
    volumes:
      - 'sail-pgsql:/var/lib/postgresql/data'
      - './vendor/laravel/sail/database/pgsql/create-testing-database.sql:/docker-entrypoint-initdb.d/10-create-testing-database.sql'
    networks:
      - socialLoginSail
    healthcheck:
      test: [ "CMD", "pg_isready", "-q", "-d", "${DB_DATABASE}", "-U", "${DB_USERNAME}" ]
      retries: 3
      timeout: 5s
networks:
  socialLoginSail:
    driver: bridge
  docker-alpine_kontentino:
    external: true
volumes:
  sail-pgsql:
    driver: local

This is mu local .env for database:

DB_CONNECTION=pgsql
DB_HOST=pgsql
DB_PORT=5432
DB_DATABASE=social-login
DB_USERNAME=admin
DB_PASSWORD=password

When I change the local port in docker-compose, Laravel cannot connect to the database.
