Gunicorn 20.x breaks use of docker Alpine Linux

[marcelvanveen]

The dependency on gunicorn 20.0.0 (committed in eb90995) breaks the web frontend on Alpine Linux docker containers (both xirixiz and ualex73):

/bin/nice -n 15 gunicorn dsmrreader.wsgi --timeout 60 --max-requests 500 --bind unix:/var/tmp/gunicorn--dsmr_reader.socket --pid /var/tmp/gunicorn--dsmr_reader.pid
Traceback (most recent call last):

    from gunicorn.app.wsgiapp import run
  File "/usr/local/lib/python3.8/site-packages/gunicorn/app/wsgiapp.py", line 9, in <module>
    from gunicorn.app.base import Application

    raise OSError('libc not found')
OSError: libc not found

More details are available in see benoitc/gunicorn#2160.

Is it possible to downgrade the required gunicorn package back to 19.9.0? As a workaround, the fix mentioned in benoitc/gunicorn#2160 (comment) works.

Thanks Marcel! Alpine Edge can install 19.9.0, Alpine 3.10 can only install 19.7.1-r2.

I removed all images with the 2.11.1 release.

Bedankt voor de melding. Welke versie is uiteindelijk gewenst? 19.9 of 19.7?

[dennissiemensma]

Ik heb de laagste gepakt. Staat nu in nieuwe release v2.11.2

[xirixiz]

Works like a charm again! Thanks!

@marcelvanveen @xirixiz weten jullie toevallig of dit inmiddels wel werkt? Issue 2160 in Gunicorn lijkt gefixt namelijk.

Is het voor jullie eenvoudig om even te testen of gunicorn==20.0.4 daadwerkelijk werkt met Alpine?
