docker-compose : Unsupported config option for services service: 'web'

问题

I am going through getting started page for docker-compose: https://docs.docker.com/compose/gettingstarted/

In Step 3, I made a docker-compose.yml file as described:

version: '2'
services:
    web:
        build: .
        ports: 
            - "5000:5000"
        volumes: 
            - .:/code
        depends_on:
            - redis
    redis:
        image: redis

But when I run:

$ docker-compose up

I get following error:

Unsupported config option for services service: 'web'

I am not able to figure out what is going on. Any help?

Thank you

回答1:

Support for the version 2 compose file format was introduced in docker-compose version 1.6, released around February of this year.

You're using 1.3.3, from July 2015.

You need to upgrade to a more recent version to use the version 2 format configuration files.
