Issue with, "st2 pack" commands through proxy about st2docs

[conor-owens]

I tried adding this to /python_action_wrapper.py to read the contents of /etc/environment:
(ref: http://stackoverflow.com/questions/5971312/how-to-set-environment-variables-in-python)

import re
import os

LOG = logging.getLogger(__name__)

def _set_env_from_etc_environment(envFilePath):
    print('--packs.py:setEnvFromEnvFile --1-----------------------------------------------.')
    SetEnvPattern = re.compile("^(.*)(=)(.*)$", re.MULTILINE)
    SetEnvFile = open(envFilePath, "r")
    SetEnvText = SetEnvFile.read()
    SetEnvMatchList = re.findall(SetEnvPattern, SetEnvText)

    for SetEnvMatch in SetEnvMatchList:
        VarName=SetEnvMatch[0]
        VarValue=SetEnvMatch[2]
        print "-- %s=%s ------"%(VarName,VarValue)
        os.environ[VarName]=VarValue

_set_env_from_etc_environment("/etc/environment")`

I also had to add 0.0.0.0 to the NO_PROXY:

NO_PROXY=localhost,127.0.0.1,0.0.0.0

This allows the command st2 run packs.install packs=st2 to succeed:

action.ref: packs.install
parameters:
  packs:
  - st2
status: succeeded

Also needed the sudo git config --global http.proxy http://proxy.somecorp.net:8080 for the git clones

Closing this now that #3137 has been resolved, and updated docs published

@sidkrishna could you take a look at this one when you get a chance? I'm not sure if the code changes are needed, or just the docs about setting environment variables.

I saw this issue too. Centos7 and Stackstorm 2.1.0. More info: https://gist.github.com/conor-owens/21d2b291251c9f89ecef579de9fb5221

Seems the various environment variables are not preserved when running the packs.py so the requests doesn't find or use the HTTPS_PROXY environment variable. In my environment sudo -v includes:
"Environment variables to preserve:
ftp_proxy
FTP_PROXY
no_proxy
http_proxy
https_proxy
NO_PROXY
HTTP_PROXY
HTTPS_PROXY"

Please note #388, that contains a more suitable workaround for st2 pack install that doesn't require any Python changes and also allows pack dependencies to install as well. Note also that it doesn't address st2 pack search at all, only pack installation.

I would like to keep this issue open, as we are going to be pursuing a more permanent solution to this problem in a future release.
