Docker compose build error - linux

Question

If I use command docker-compose build, I'll get error that looks like:
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]'
I use the last version docker and docker-compose.
My docker-compose.yml has the next code:
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
I use an ubuntu 14.04
Could you tell me how is fix it?

Answer 1

You need to put the port definitions in quotes for short ports (2 digits). This is a result of the nature of YAML and the used parser in docker-compose.
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
Also the expose statement should come with a single number only and also be quoted.
Added all needed changes in the above.
