执行 docker-compose 命令后出现错误 yaml.scanner.ScannerError

Question

Docker 撰写文件：

version: '2'

services:

wordpress:
    image: wordpress
    ports:
        -8080:80
    environment:
        WORDPRESS_DB_PASSWORD:vvk123
mysql:
    image:mysql:latest
    environment:
        MYSQL_ROOT_PASSWORD:vvk123

当我试图执行这个命令时

docker-compose ps

它的错误被称为

yaml.scanner.ScannerError: 此处不允许映射值 “.\docker-compose.yml”，第 12 行，第 20 列

Answer 1

尝试在第 12 行的列之后添加一个空格：

version: '2'

services:

wordpress:
    image: wordpress
    ports:
        - 8080:80
    environment:
        - WORDPRESS_DB_PASSWORD:vvk123
mysql:
    image: mysql:latest
    environment:
        - MYSQL_ROOT_PASSWORD:vvk123
