How to containerize laravel and postgres using docker?

Please help with code for dockerfile and docker-compose file i need laravel setup and postgres.

This is my docker file

FROM php:7.4

RUN apt-get update && apt-get install -y 
        libfreetype6-dev 
        libjpeg62-turbo-dev 
        libmcrypt-dev 
        libpng-dev 
        zlib1g-dev 
        libpq-dev 
        libxml2-dev 
        libzip-dev 
        libonig-dev 
        graphviz 
    && docker-php-ext-configure gd 
    && docker-php-ext-install -j$(nproc) gd 
    && docker-php-ext-install pdo_mysql 
    && docker-php-ext-install pdo_psql 
    && docker-php-ext-install zip 
    && docker-php-ext-install sockets 
    && docker-php-source delete 
    && curl -sS https://getcomposer.org/installer | php -- 
     --install-dir=/usr/local/bin --filename=composer

WORKDIR /var/www/html
COPY . .
RUN composer install

CMD php artisan serve --host=0.0.0.0
EXPOSE 8000

this is docker-compose.yml file

version: '3'
services:
  php_4:
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - ./:/var/www/html
    ports:
      - "8000:8000"
    depends_on:
      - postgres_4

  postgres_4:
    image: postgres
    restart: unless-stopped
    ports:
      - "5433:5432"
    volumes:
      - ./docker/postgres:/var/lib/postgresql/data
    environment:
      POSTGRES_USER: root
      POSTGRES_PASSWORD: root
      POSTGRES_DB: lara_4
      POSTGRES_HOST_AUTH_METHOD: "trust"

Both are not working giving different different errors. SO please anyone give fresh code for both dockerfile and docker-compose file for laravel with postgresql using docker.
