这里不允许 yml docker-compose 错误映射值

问题描述

我尝试了解容器，但我的 docker-compose.yml 文件有问题，在我运行 docker compose up 后，我总是遇到相同的错误:

I try to learn about container, but i have a problem with my docker-compose.yml file, after i run the docker compose up, i always get the same error:

"错误:yaml.scanner.ScannerError:不允许映射值这里"

即使我将挂载路径更改为 docker 卷，我也遇到了同样的错误，这是我的 yml 文件

even if i changed the mount path to docker volume, i got the same error, this is my yml file

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

推荐答案

您的 yaml 似乎无效.当我遇到这些类型的问题时，我会做的是使用一个名为 http://www.yamllint.com/ 将为您验证语法.

It appears that your yaml is invalid. When I face these types of issues, what I will do is use a site called http://www.yamllint.com/ which will validate the syntax for you.

这个基于你的例子的 yaml 是有效的:

This yaml based on your example is valid:

注意:您可以使用 4 个空格(或我更喜欢的 2 个)，但切勿使用制表符.

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
