Docker Compose YAML文件中youmas服务环境配置错误求助

问题分析 #

你的youmas服务存在两个关键问题：

1. 缺少镜像或构建配置：Docker Compose无法确定启动该服务所需的镜像文件，这是导致配置错误的核心原因。
2. 你最初提供的错误示例中存在YAML缩进错误：environment下的XDEBUG_CONFIG未按层级正确缩进（虽然完整代码里缩进已修正，但需注意YAML对缩进要求严格，必须保持一致的缩进层级）。

解决方案 #

针对上述问题，给出两种常见修复方式：

方式一：复用已有的youmas-app镜像 #

如果youmas服务是基于已定义的youmas-app镜像创建，只需添加image字段指定镜像：

youmas:
  image: youmas-app  # 添加镜像配置，复用已构建的youmas-app镜像
  environment:
    XDEBUG_CONFIG: remote_host=172.17.0.1 remote_port=9000 remote_enable=1
  networks:
    - youmas

方式二：指定单独的构建配置 #

如果youmas服务需要使用独立的Dockerfile，添加build字段定义构建规则：

youmas:
  build:
    context: .
    dockerfile: ./path/to/your/Dockerfile  # 替换为实际Dockerfile的路径
  environment:
    XDEBUG_CONFIG: remote_host=172.17.0.1 remote_port=9000 remote_enable=1
  networks:
    - youmas
