Docker-将phpmyadmin和mysql合并在一起进行本地开发

version: "3.1" services: redis: image: redis:alpine container_name: larablog-redis 

代码工作正常，直到我添加以下服务

  db: image: mysql:8.0 container_name: larablog-mysql working_dir: /application volumes: - ./src:/application environment: - MYSQL_ROOT_PASSWORD=rootpass - MYSQL_DATABASE=larablog - MYSQL_USER=larauser - MYSQL_PASSWORD=larauserpass ports: - "8890:3306" phpmyadmin: image: phpmyadmin/phpmyadmin environment: PMA_ARBITRARY: 1 MYSQL_USER: larauser MYSQL_PASSWORD: larauserpass MYSQL_ROOT_PASSWORD: rootpass ports: - "80:80" links: # for mysql container - "db:db" volumes: db: driver: "local" 

我试图按照我在https://gotechnies.com/docker-compose-yml-mysql-phpmyadmin/上find的方法，但是我不能从头开始，因为我还需要laravel框架

  webserver: image: nginx:alpine container_name: larablog-webserver working_dir: /application volumes: - ./src:/application - ./phpdocker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf ports: - "8888:80" php-fpm: build: phpdocker/php-fpm container_name: larablog-php-fpm working_dir: /application volumes: - ./src:/application - ./phpdocker/php-fpm/php-ini-overrides.ini:/etc/php/7.1/fpm/conf.d/99-overrides.ini 

我得到这个错误，当我尝试运行docker组成 – D …

 ERROR: yaml.parser.ParserError: while parsing a block mapping in ".\..\docker-compose.yml", line 27, column 6 expected <block end>, but found '<block mapping start>' in ".\..\docker-compose.yml", line 35, column 9 

我怎样才能克服这个错误？
