What is the urllib3 documentation telling me to do?


I am trying to get a Kilo OpenStack cloud deployed and I was getting this error:

Execution of '/usr/bin/openstack token issue --format value' returned 1: /usr/lib/python2.7/site-packages/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see

So I go to: https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning

I find out that I do not have access to a python version better than 2.7.5 so I look at:

https://urllib3.readthedocs.org/en/latest/security.html#pyopenssl

So do what they recommend I do ...

# pip install pyopenssl ndg-httpsclient pyasn1
/usr/lib/python2.7/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.

The docs also say this:

Once the packages are installed, you can tell urllib3 to switch the ssl backend to PyOpenSSL with inject_into_urllib3():

import urllib3.contrib.pyopenssl urllib3.contrib.pyopenssl.inject_into_urllib3() Now you can continue using urllib3 as you normally would.

I do not understand what that means? Is there some python source code I need to go patch?

Update:

I did as suggested by Josep and this is what is happening:

# python
Python 2.7.5 (default, Jun 24 2015, 00:41:19) 
[GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import urllib3
>>> import pyopenssl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named pyopenssl

Yet I have pyopenssl installed ...

# pip install pyopenssl
Requirement already satisfied (use --upgrade to upgrade): pyopenssl in /usr/lib64/python2.7/site-packages

UPDATE:

Here's what happens if I do this ...

# python
Python 2.7.5 (default, Jun 24 2015, 00:41:19) 
[GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2

>>> import OpenSSL
>>> import urllib3
>>> import urllib3.contrib.pyopenssl as pyopenssl
>>> pyopenssl.inject_into_urllib3()
>>> 

Solution

  • I understand that you are using OpenStack which uses urllib3. So yes, if you want to go that avenue and "patch" OpenStack, look for something like import .*urllib3.* or from urllib3 import .* and after every instance add the two lines they instruct you to add.
