Cannot start services when ports are mentioned

[drgroot]

For some reason I cannot bind the port correctly. When I remove the port, it works. If i change the port to any other number, it still does not work

version: '3'
services:
  rtorrent:
    container_name: rtorrent
    image: yusufali/rtorrent
    privileged: true
  web_nginx:
    container_name: web_nginx
    image: marvambass/nginx-ssl-secure
    links:
      - rtorrent:rtorrent
    ports:
      - "8800:80"

However, run I run docker-com up -d, this does not work

Creating network "docker_default" with the default driver
Creating rtorrent
Creating web_nginx

ERROR: for web_nginx  Cannot create container for service web_nginx: invalid port specification: "None"
ERROR: Encountered errors while bringing up the project.

Useful info:

That same setup works fine for me. Is that your entire docker-compose.yml file? Do you have a docker-compose.override.yml?

[drgroot]

No i do not.

[shin-]

Have you tried to isolate the issue into a smaller example? Do you still see the same bug with a simpler Compose file, e.g.

version: '3'
services:
  foo:
    image: alpine
    ports:
      - "8800:80"

Make sure it's in a separate, empty folder.

[drgroot]

same issue. done in a separate folder.

Its really weird cuz it works fine when I manually perform the operation using the 'docker create -p ...' command

[shin-]

Hmm, that's interesting. Did you install Compose using pip or did you download the binary? If you're using pip, what's your python --version? Also, could you run the following commands and share the output:

• docker-compose config
• docker-compose --verbose up -d

[drgroot]

pip3 install --upgrade docker-compose

$ python3 --version
  Python 3.4.2

For the docker-compose config:

It might be an issue with Python 3 - I'll take another look. In the meantime, you might want to try using Python 2.7 instead and see if the issue still occurs.

[drgroot]

okay, switching to python 2 works.

[dalberto]

I've experienced the same issue on Python 3.5, installed via pip. Similarly, using python 2 fixes the issue. I experienced the issue with file versions 2.1 and 3.0, 3.2 but not 3.1.

[dpdornseifer]

Hi experiencing the same problem just with Python3.5.0. 2.7 and 3.5.1 / 3.5.2 / 3.5.3 are working fine. A quickfix for me right now is to to use docker-compose < 1.12.0

[shin-]

I believe this Python bug is the cause of the issue: https://bugs.python.org/issue24931 Upgrading to Python 3.4.4+ or 3.5.1+ should fix it.

[svitlanacs]

@dpdornseifer could you, please, share the command you used to downgrade the docker-compose?

Found it! For anybody interested in how to downgrade docker-compose, this link was useful for me: https://www.digitalocean.com/community/tutorials/how-to-install-docker-compose-on-ubuntu-16-04

[shin-]

@svitlanacs Please note that a much better solution would be to upgrade your Python installation.

[svitlanacs]

@shin- absolutely. But I'm running Ubuntu 14.04, so downgrading docker-compose was a simpler solution.

[z3ntu]

I also downgraded to 1.11.2 as the Python version on Ubuntu 14.04 is 3.4.3.

[harpcio]

I have the same issue on python 2.7.6 / ubuntu 14.04.05 LTS with docker-compose version: "2.1". Switching to version: '2' have fixed the problem.

[OleksiiStepanov]

I had same error with my port map and i solved that. Just wrote a map as string

ports:
    - 8080:80
... 

replace with:

ports:
    - "8080:80"
...

i am using docker-compose version 1.21.2, build a133471
