Package: gunicorn Version: 0.10.0-1
I'm attaching in this message an initscript to manage gunicorn_django environments. I currently run gunicorn_django in my servers and manage differents environtments/projects using this single initscript and the respective configuration files. The initscript have a default configuration file[1] and each django project should have an additional configuration file[2]. The default configuration have the default parameters and they can/should be overwrriten in the specific configuration files of the django project. I don't know if it's the best approach or if we should use a directory /etc/gunicorn_django.d/<django-project-config> and I would be glad if you could point a better way. I'm currently using this initiscript in my production environment and it have been working very well. [1]. /etc/default/gunicorn_django [2]. /etc/default/gunicorn_django-myprojectname A more complete version of the code (with some documentation and usage examples) are available in my github page[3].
