Compose doesn't work with SOCKS proxy

[savermyas]

Hello.
I am using the Docker and Docker Compose in OS X and need to use the SOCKS proxy to reach remote Docker Engines. And looks like Docker Compose doesn't support it despite Docker does.

My environment is the following:

bash-3.2$ uname -a
Darwin myhost 15.5.0 Darwin Kernel Version 15.5.0: Tue Apr 19 18:36:36 PDT 2016; root:xnu-3248.50.21~8/RELEASE_X86_64 x86_64


bash-3.2$ docker version
Client:
 Version:      1.11.2
 API version:  1.23
 Go version:   go1.5.4
 Git commit:   b9f10c9
 Built:        Wed Jun  1 21:20:08 2016
 OS/Arch:      darwin/amd64

Server:
 Version:      1.11.1
 API version:  1.23
 Go version:   go1.5.4
 Git commit:   5604cbe
 Built:        Wed Apr 27 00:34:42 2016
 OS/Arch:      linux/amd64


bash-3.2$ docker-compose version
docker-compose version 1.7.1, build 0a9ab35
docker-py version: 1.8.1
CPython version: 2.7.9
OpenSSL version: OpenSSL 1.0.1j 15 Oct 2014

Please, consider the following actions:

1. Docker supports the ALL_PROXY environment variable:

bash-3.2$ ALL_PROXY=socks5://localhost:31457 docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

2. Docker Compose doesn't:

bash-3.2$ ALL_PROXY=socks5://localhost:31457 docker-compose ps
ERROR: Couldn't connect to Docker daemon - you might need to run `docker-machine start default`.

3. And in case of HTTPS_PROXY environment variable usage we get another error:

bash-3.2$ HTTPS_PROXY=socks5://localhost:31457 docker-compose ps

Same problem here :(
Just seen that sock5 support was added to requests in version 2.10 but compose is using version 2.7.0 right now:

https://pypi.python.org/pypi/requests/2.11.1

2.10.0 (2016-04-29)

New Features

SOCKS Proxy Support! (requires PySocks; $ pip install requests[socks])

We are now using requests 2.20.0 for ages (and recently bumped to 2.22.0), which I suppose is new enough. We also now include PySocks.

So after such a long time I'm going to preemptively assume this is fixed and closed, please ping if I am mistaken.

BTW, I think as of one of the more recent releases docker-py supports remote access via ssh too, in case that is useful in your environment.
