Docker compose提供了无效的环境类型错误

Question

我是第一次实现bitnami-docker-wordpress。这些是我在yml文件中的配置。

version: '3'

services:
  # Database
  mariadb:
    image: 'bitnami/mariadb:latest'
    ports:
      - '3306:3306'
    volumes:
      - mariadb_data:/var/lib/mysql
    restart: always
    environment:
      # ALLOW_EMPTY_PASSWORD is recommended only for development.
      # - ALLOW_EMPTY_PASSWORD=no
      - MARIADB_USER: wordpress
      - MARIADB_PASSWORD: wordpress
      - MARIADB_ROOT_PASSWORD: wordpress
      - MARIADB_DATABASE: wordpress
    networks:
      - wpsite
  # Wordpress
  wordpress:
    depends_on:
      - mariadb
    image: 'bitnami/wordpress:latest'
    ports:
      - '8000:80'
    restart: always
    volumes: ['./:/var/www/html']
    environment:
      - WORDPRESS_DB_HOST: mariadb:3306
      - WORDPRESS_DB_USER: wordpress
      - WORDPRESS_DB_PASSWORD: wordpress
    networks:
      - wpsite
networks:
  wpsite:
volumes:
  mariadb_data:
    driver: local

现在，当我尝试运行docker-compose up -d时，我得到了以下错误：

ERROR: The Compose file '.\docker-compose.yml' is invalid because:
services.mariadb.environment contains {"MARIADB_USER": "wordpress"}, which is an invalid type, it should be a string
services.wordpress.environment contains {"WORDPRESS_DB_HOST": "mariadb:3306"}, which is an invalid type, it should be a string

有人能帮我解决这个配置吗？

谢谢。

尝尝这个

version: '3'

services:
  # Database
  mariadb:
    image: 'bitnami/mariadb:latest'
    ports:
      - '3306:3306'
    volumes:
      - mariadb_data:/var/lib/mysql
    restart: always
    environment:
      # ALLOW_EMPTY_PASSWORD is recommended only for development.
      # - ALLOW_EMPTY_PASSWORD=no
      MARIADB_USER: wordpress
      MARIADB_PASSWORD: wordpress
      MARIADB_ROOT_PASSWORD: wordpress
      MARIADB_DATABASE: wordpress
    networks:
      - wpsite
  # Wordpress
  wordpress:
    depends_on:
      - mariadb
    image: 'bitnami/wordpress:latest'
    ports:
      - '8000:80'
    restart: always
    volumes: ['./:/var/www/html']
    environment:
      WORDPRESS_DB_HOST: mariadb:3306
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: wordpress
    networks:
      - wpsite
networks:
  wpsite:
volumes:
  mariadb_data:
    driver: local

环境参数可以定义为

environment:
  param1:value1
  param2:value2

或

environment:
  - param1=value1
  - param2=value2

Answer 2

该错误是因为您在环境中使用来自wordpress的字符-。

environment:
      - WORDPRESS_DB_HOST: mariadb:3306
      - WORDPRESS_DB_USER: wordpress
      - WORDPRESS_DB_PASSWORD: wordpress

并且应该是：

environment:
      WORDPRESS_DB_HOST: mariadb:3306
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: wordpress
