docker - 执行docker-compose命令后获得错误yaml.scanner.ScannerError

Question

Docker撰写文件:

services:

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

当我试图执行此命令时

docker-compose ps

它的给定错误称为

yaml.scanner.ScannerError: mapping values are not allowed here in ".\docker-compose.yml", line 12, column 20

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
