gevent not valid running Docker Registry

I am attempting to run a Docker registry on Ubuntu 14 using the following command:

sudo gunicorn --access-logfile - --debug -k gevent -b 0.0.0.0:5000 -w 1 docker_registry.wsgi:application

Unfortunately, when I attempt this I get the following failure message:

Error: class uri 'gevent' invalid or not found:



[Traceback (most recent call last):

  File "/usr/local/lib/python2.7/dist-packages/gunicorn/util.py", line 139, in load_class

    mod = import_module('.'.join(components))

  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module

    __import__(name)

  File "/usr/local/lib/python2.7/dist-packages/gunicorn/workers/ggevent.py", line 24, in <module>

    from gevent.server import StreamServer

    from gevent.socket import EWOULDBLOCK, socket

  File "/usr/local/lib/python2.7/dist-packages/gevent/socket.py", line 659, in <module>

    from gevent.ssl import sslwrap_simple as ssl, SSLError as sslerror, SSLSocket as SSLType

  File "/usr/local/lib/python2.7/dist-packages/gevent/ssl.py", line 386, in <module>

    def get_server_certificate(addr, ssl_version=PROTOCOL_SSLv3, ca_certs=None):

NameError: name 'PROTOCOL_SSLv3' is not defined

I did some searching and discovered something that told me to install python-gevent in order to get the gevent:

sudo apt-get install python-gevent

I did this and a subsequent invocation of dpkg:

dpkg -l|grep python

shows that python-gevent is installed.

Unfortunately, the install has not resolved the problem. I am still getting the same failure message saying that gevent isn't valid or found.

Does anyone know how to resolve this problem??? Please advise...

If you're getting this in late 2022 or later, know that gevent versions 20.9.0 and earlier depend on greenlet, without specifying an upper bound on that version. greenlet has just released a breaking change in v2.x.x, and gevent doesn't work with it.

Pinning greenlet=1.1.3 fixed it for me. More details about this issue here: https://github.com/python-greenlet/greenlet/issues/178

try it:

1.find your python gevent package folder:

$ cd /usr/local/lib/python2.7/dist-packages/gevent

2.update ssl.py

from:

def get_server_certificate(addr, ssl_version=PROTOCOL_SSLv3, ca_certs=None):

to:

def get_server_certificate(addr, ssl_version=PROTOCOL_SSLv23, ca_certs=None):

3.try again:

$sudo gunicorn --access-logfile - --debug -k gevent -b 0.0.0.0:5000 -w 1 docker_registry.wsgi:application
