docker - 此处不允许yml docker-compose错误映射值

Question

我尝试了解容器，但是我的docker-compose.yml文件有问题，在运行docker compose之后，我总是会遇到相同的错误:

"ERROR: yaml.scanner.ScannerError: mapping values are not allowed here"

即使我将安装路径更改为docker volume，我也遇到了同样的错误，这是我的 yml文件

version: "3"

services:
    database:
        image: mariadb
        ports: 
            - "3260:3260"
        volumes:
            - /home/randy/Desktop/Latihan/wordpress-mariadb/mariadb:var/lib/mysql
         environment:
            MYSQL_ROOT_PASSWORD: root

    wordpress:
        image: wordpress
        ports:
            - "2000:80"
        volumes:
            - /home/randy/Desktop/Latihan/wordpress-mariadb/wordpress:/var/www/html
        environment:
            WORDPRESS_DB_PASSWORD: root
        depends_on:
            - database
        links:
            - database

Answer 1

您的Yaml似乎无效。当我遇到这些类型的问题时，我将使用名为http://www.yamllint.com/的站点来为您验证语法。

根据您的示例，这个Yaml是有效的:

注意:您可以使用4个空格(或2个我更喜欢的空格)，但决不能使用制表符。

version: "3"

services: 
  database: 
    environment: 
      MYSQL_ROOT_PASSWORD: root
    image: mariadb
    ports: 
      - "3260:3260"
    volumes: 
      - "/home/randy/Desktop/Latihan/wordpress-mariadb/mariadb:var/lib/mysql"
  wordpress:
    image: wordpress
    ports:
      - "2000:80"
    volumes:
      - /home/randy/Desktop/Latihan/wordpress-mariadb/wordpress:/var/www/html
    environment:
      WORDPRESS_DB_PASSWORD: root
    depends_on:
      - database
    links:
      - database
