Compose filedocker-compose.yml‘无效，因为环境包含无效的类型，它应该是对象或数组

Question

我在一个亚洲站点上找到了这个docker compose容器，并试图运行它，然后我得到了以下内容。我不得不修改docker撰写文件，因为有重复的字符。我不确定为什么它不能运行，我已经在stackoverflow上寻找了其他问题，但都没有解决我的问题。

docker组成文件如下：

---
version: '3.5'
services:
    wowonder-web:
        container_name: wowonder-web
        image: webdevops/php-apache:debian-10
        environment:
            -WEB_DOCUMENT_ROOT=/app
            -PHP_MEMORY_LIMIT=1024M
            -PHP_MAX_EXECUTION_TIME=7200
            -PHP_POST_MAX_SIZE=10240M
            -PHP_UPLOAD_MAX_FILESIZE=10240M
            -FPM_MAX_REQUESTS=500
            -FPM_PM_MAX_CHILDREN=20
            -FPM_PM_START_SERVERS=10
            -FPM_PM_MIN_SPARE_SERVERS=5
            -FPM_PM_MAX_SPARE_SERVERS=15
        
        volumes: 
            - /opt/wowonder/app:/appwowonder:/app
        restart: unless-stopped

    wowonder-db:
        container_name: wowonder-db
        image: mariadb
        environment: 
            -MYSQL_ROOT_PASSWORD="wowonder"
            -MYSQL_PASSWORD="wowonder"
            -MYSQL_DATABASE="wowonder"
            -MYSQL_USER="wowonder"
        volumes: 
            - /docker/Databases/wowonder:/var/lib/mysqldb
            command: --sql-mode="NO_ENGINE_SUBSTITUTION"  
        restart: unless-stopped

几个输入错误(请在将来检查this online YAML验证器)：

首先，正如@DavidMaze指出的那样，要在docker-compose文件中创建一个YAML数组，最流行的选择是为每个元素创建一个新行，并以连字符和空格开头，您可以在this中浏览其他选项，以便线程

        environment:
            - WEB_DOCUMENT_ROOT=/app
            - PHP_MEMORY_LIMIT=1024M
            - PHP_MAX_EXECUTION_TIME=7200
            - PHP_POST_MAX_SIZE=10240M
            - PHP_UPLOAD_MAX_FILESIZE=10240M
            - FPM_MAX_REQUESTS=500
            - FPM_PM_MAX_CHILDREN=20
            - FPM_PM_START_SERVERS=10
            - FPM_PM_MIN_SPARE_SERVERS=5
            - FPM_PM_MAX_SPARE_SERVERS=15

其次，您的wowonder-db命令缩进太多，后退一步解决了这个问题。

        volumes: 
            - /docker/Databases/wowonder:/var/lib/mysqldb
        command: --sql-mode="NO_ENGINE_SUBSTITUTION"  
        restart: unless-stopped
