Compose: Missing dependency on Ubuntu 16.04

[dooman87]

I used original docker instruction (https://docs.docker.com/engine/installation/linux/ubuntulinux/) to install docker on ubuntu 16.04 that was created in GCP. It worked like a charm and manual is really great!

However, docker compose didn't work out of the box:

:~$ docker-compose --version
Traceback (most recent call last):
  File "/usr/bin/docker-compose", line 9, in <module>
    load_entry_point('docker-compose==1.5.2', 'console_scripts', 'docker-compose')()

    import ipaddress
ImportError: No module named ipaddress

I was able to fix it by installing python-ipaddress package:

@dooman87 which python are you using, IIRC 16.04 uses Python 3.5 as default one. If so, docker-compose doesn't support it yet. And it looks like that this is a problem of python docker client but not compose itself.

[dooman87]

@denismakogon nope, it's 2.7:

:~$ python --version
Python 2.7.11+

[garcianavalon]

I'm facing the same issue on ubuntu 16.04, with python 2.7.11+ too

[denismakogon]

Let's start with documentation as initial solution. For next fixes it would
require to analyze package diff and find out what causes problem described
above.

@denismakogon I created a PR with a change to docs.

had this also with fresh install of Ubuntu 16.04. Install python-ipaddress package resolved problem.

Almost a year and Docker won't even add this to their documentation!?

Fixed in #3661
