Incorrect docker compose on phpmyadmin

Question

According to the docker compose yaml,

version: '3'
services:
  db:
    image: mariadb:latest
    container_name: mariadb
    restart: always
    volumes:
      - ./mysql/initdb/:/docker-entrypoint-initdb.d
      - ./mysql/data/:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=root-pwd
      - MYSQL_DATABASE=appdb
      - MYSQL_USER=appuser
      - MYSQL_PASSWORD=user-pwd
  php:
    image: php:fpm-alpine
    container_name: php
    restart: always
    volumes:
      - ./www/:/var/www/html
    expose:
      - "9000"
  nginx:
    image: nginx:alpine
    container_name: nginx
    restart: always
    volumes:
      - ./nginx/conf/nginx.conf:/etc/nginx/conf/nginx.conf:ro
      - ./nginx/conf.d:/etc/nginx/conf.d:ro
      - ./www:/var/www/html
    ports:
      - "80:80"
  pma:
    image: phpmyadmin/phpmyadmin
    container_name: phpmyadmin
    restart: always
    ports:
      - "8080:80"

it produces an error:

#2002 - php_network_getaddresses: getaddrinfo failed: Try again — The server is not responding (or the local server's socket is not correctly configured).

when logging in to phpMyadmin (http://127.0.0.1:8080).

I have tried to fix this problem, but nothing works. Could you please find a solution? Any recommendations/comments are welcomed here.

you should links your phpmyadmin to database services in order to use the db service

pma:
    image: phpmyadmin/phpmyadmin
    links:
      - db
    container_name: phpmyadmin
    restart: always
    ports:
      - "8080:80"
    environment:
      - PMA_HOST: maria_db
