Question

我想创建一个 .yml文件，我可以执行该文件以将wordpress与mysql一起使用。我是关于docker composoe的docker的新手，所以我的代码是：

web:
    image: wordpress
    links:
     - mysql
    environment:
     - WORDPRESS_DB_PASSWORD=sample
    ports:
     - "127.0.0.3:8080:80"
mysql:
image: mysql:latest
environment:
 - MYSQL_ROOT_PASSWORD=sample
 - MYSQL_DATABASE=wordpress

我做docker-compose up并收到此错误：

ERROR: In file './docker-compose.yml', service 'image' must be a mapping not a string.

有人可以帮助我吗？

Answer 1

这是Yaml格式错误。您应该这样格式化

web:
    image: wordpress
    links:
     - mysql
    environment:
     - WORDPRESS_DB_PASSWORD=sample
    ports:
     - "127.0.0.3:8080:80"
mysql:
    image: mysql:latest
    environment:
     - MYSQL_ROOT_PASSWORD=sample
     - MYSQL_DATABASE=wordpress

Answer 2

mysql:附近的缩进是错误的，请按以下说明更正缩进

web:
image: wordpress
links:
 - mysql
environment:
 - WORDPRESS_DB_PASSWORD=sample
ports:
 - "127.0.0.3:8080:80"
mysql:
    image: mysql:latest
    environment:
    - MYSQL_ROOT_PASSWORD=sample
    - MYSQL_DATABASE=wordpress

您可以在https://onlineyamltools.com/validate-yaml上验证yml

在文件'./docker-compose.yml'中，服务'image'必须是映射而不是字符串
