Hi everyone!
I cannot find any docs about compose’s requirements.
Python
It starts during the installation: When following the docs, it reads:
If you have problems installing with curl, you can use pip instead:
pip install -U docker-compose
I cannot find the info if pip of Python2 or Python3 has to be used. The same is for compose itself: Has it to be used with Python2 or Python3?
Docker Engine/Client
Also, I cannot find anything about what Docker Engine/Client is needed to have latest compose (1.4.0) running.
I’m using Ubuntu 15.04 (vivid). This is shipped with the following Docker components:
Client version: 1.5.0
Client API version: 1.17
Go version (client): go1.3.3
Git commit (client): a8a31ef
OS/Arch (client): linux/amd64
Server version: 1.5.0
Server API version: 1.17
Go version (server): go1.3.3
Git commit (server): a8a31ef
I followed the Quickstart Guide for Wordpress and this is what I get when I run docker-compose up:

Seems as if my Docker version isn’t recent enough to use docker-compose … yesterday, somehow, I got another error, saying client and server don't have same version. No idea how I managed it to be gone and replaced by the error showed above …
So: What exactly are the requirements for latest docker-compose and how best to achieve them on a Ubuntu 15.04 system, without messing up the package database?
