gunicorn autoreload on source change

Question

Finally I migrated my development env from runserver to gunicorn/nginx.

It\'d be convenient to replicate the autoreload feature of runserver to gunicorn, so the serv

I use git push to deploy to production and set up git hooks to run a script. The advantage of this approach is you can also do your migration and package installation at the same time. https://mikeeverhart.net/2013/01/using-git-to-deploy-code/

mkdir -p /home/git/project_name.git
cd /home/git/project_name.git
git init --bare

Then create a script /home/git/project_name.git/hooks/post-receive.

#!/bin/bash
GIT_WORK_TREE=/path/to/project git checkout -f
source /path/to/virtualenv/activate
pip install -r /path/to/project/requirements.txt
python /path/to/project/manage.py migrate
sudo supervisorctl restart project_name

Make sure to chmod u+x post-receive, and add user to sudoers. Allow it to run sudo supervisorctl without password. https://www.cyberciti.biz/faq/linux-unix-running-sudo-command-without-a-password/

From my local / development server, I set up git remote that allows me to push to the production server

git remote add production ssh://user_name@production-server/home/git/project_name.git

# initial push
git push production +master:refs/heads/master

# subsequent push
git push production master

As a bonus, you will get to see all the prompts as the script is running. So you will see if there is any issue with the migration/package installation/supervisor restart.
