linux – Docker构成构建错误

如果我使用命令docker-compose build,我将得到如下错误：

ERROR: Validation Failed in file './docker-compose.yml', reason(s):
Service 'PHP' configuration key 'expose' '0' is invalid: should be of
the format 'PORT[/PROTOCOL]'

我使用最新版本的docker和docker-compose.

我的docker-compose.yml有下一个代码：

application:
    build: code
    volumes:
        - ./symfony:/var/www/symfony
        - ./logs/symfony:/var/www/symfony/app/logs
    tty: true
db:
    image: MysqL
    ports:
        - 3306:3306
    environment:
        MysqL_ROOT_PASSWORD: root
        MysqL_DATABASE: symfony
        MysqL_USER: root
        MysqL_PASSWORD: root
PHP:
    build: PHP-fpm
    expose:
        - 9000:9000
    volumes_from:
        - application
    links:
        - db
Nginx:
    build: Nginx
    ports:
        - 80:80
    links:
        - PHP
    volumes_from:
        - application
    volumes:
        - ./logs/Nginx/:/var/log/Nginx
elk:
    image: willdurand/elk
    ports:
        - 81:80
    volumes:
        - ./elk/logstash:/etc/logstash
        - ./elk/logstash/patterns:/opt/logstash/patterns
    volumes_from:
        - application
        - PHP
        - Nginx

我使用的是ubuntu 14.04
你能告诉我怎么解决它？

解决方法:

您需要将端口定义放在短端口(2位数)的引号中.这是YAML的性质和docker-compose中使用的解析器的结果.

application:
    build: code
    volumes:
        - ./symfony:/var/www/symfony
        - ./logs/symfony:/var/www/symfony/app/logs
    tty: true
db:
    image: MysqL
    ports:
        - "3306:3306"
    environment:
        MysqL_ROOT_PASSWORD: root
        MysqL_DATABASE: symfony
        MysqL_USER: root
        MysqL_PASSWORD: root
PHP:
    build: PHP-fpm
    expose:
        - "9000"
    volumes_from:
        - application
    links:
        - db
Nginx:
    build: Nginx
    ports:
        - "80:80"
    links:
        - PHP
    volumes_from:
        - application
    volumes:
        - ./logs/Nginx/:/var/log/Nginx
elk:
    image: willdurand/elk
    ports:
        - "81:80"
    volumes:
        - ./elk/logstash:/etc/logstash
        - ./elk/logstash/patterns:/opt/logstash/patterns
    volumes_from:
        - application
        - PHP
        - Nginx

曝光语句也应仅包含一个数字,并且也应引用.
在上面添加了所有必需的更改.
