What does it do?

Using Fabric to run a management command on each remote instance to redeploy itself.

The remote command will pull the source code from Git, run all necessary Django management commands, and restart the server.

Requirements

• A deployed instance running either:

  • Apache with mod_WSGI
  • GUnicorn

• Fabric

• A Git hosted repository for the project

Installation

Add the app to your INSTALLED_APPS setting:

INSTALLED_APPS = (
    #...
    'sitepush',
)

Settings

Add the server configuration to your settings file:

DEPLOYS = {
    'default': {
        'HOST': '192.168.0.1',         # IP or domain name
        'USER': 'user',                # User to login with
        'BRANCH': 'master',            # Git branch to pull updates from
        'SETTINGS': 'settings',        # Settings file to use (optional)
        'DIR': '/var/www/myproject/',
        'ENV': 'myvirtualenv',         # virtualenv used in the project
        'WEBSERVER': 'gunicorn',       # webserver - 'apache' or 'gunicorn'

        'PID_FILE': '/tmp/gunicorn.pid',  # Gunicorn pid file path
        'WSGI_FILE': 'deploy/wsgi.py',    # Apache wsgi file path
    },
}

The PID_FILE / WSGI_FILE settings should be set depending on the web server you're using.

BRANCH is optional and defaults to master
