Python Bureaucrat

Bureaucrat provides support for Deployfile based deployment task management. A Deployfile is basically a Procfile by another name. It is used to define the deployment commands for your project and spawn the processes required to run it.

Deployfile commands must be idempotent.

If you're using Docker then you might find this useful to automate your container builds.

Installation

Install from PyPI with:

pip install bureaucrat

Or install from source with:

pip install git+https://github.com/adlibre/python-bureaucrat.git#egg=bureaucrat  

Config

To use Bureaucrat you will need to create a Procfile, Deployfile and .env file in your virtual env root.

Sample Procfile

The following will spawn a single gunicorn web process.

web: gunicorn project.wsgi:application --workers $WORKERS --log-file $LOGFILE --bind 0.0.0.0:$PORT --timeout 300

Sample Deployfile

The following is suitable for deploying a Django application.

pip: pip install -r requirements.txt
migrate: manage.py migrate --noinput
collectstatic: manage.py collectstatic --noinput

Sample .env

WORKERS=4
LOGFILE=/var/log/django-project.log
PORT=8000

Usage

Basic options are start, stop, restart, deploy and init.

usage: Bureaucrat [-h] {start,stop,restart,deploy,init} ...

  --venv VENV          Virtualenv root
  --app APP            Application root
  --procfile PROCFILE  Procfile path
  --envfile ENVFILE    .env file path
  --logpath LOGPATH    log file path
  --pidpath PIDPATH    pid file path

Example:
