dploi-fabric 0.2.1

A collection of fabric tasks

This is a set of reusable fabric tasks. It uses the new-style task system of fabric >= 1.2

Usage

• Add dploi-fabric to your buildout environment (preferably in development_local.cfg, the servers have no use for it).

• Create a fabfile.py as normal.

• Pick and choose the modules and import them in the fabfile.py, e.g.:

  from fabric.decorators import task
  
  from dploi_fabric.db import pg # if project uses mysql, import "mysql" instead
  from dploi_fabric import supervisor, nginx
  from dploi_fabric import git, utils, buildout, south, django_utils, project
  
  from dploi_fabric.conf import load_settings
  
  @task
  def dev():
      load_settings('dev')
  
  @task
  def stage():
      load_settings('stage')
  
  @task
  def live():
      load_settings('live')
  
  @task
  def deploy():
      pg.dump.run()
      git.update()
      buildout.run()
      south.migrate.run()
      django_utils.collectstatic()
      supervisor.restart()
      supervisor.status()
      nginx.update_config_file()

• in the project root, create a file deployment.py following this template:

  project_name = 'awesome_new_website'
  
  settings = {
      'dev': {
          'hosts': ['yourserver.com'],
          'autostart': True,
          'path': '/home/awesome_new_website-dev/app/',
          'user': 'awesome_new_website-dev',
          'buildout_cfg': 'server_dev.cfg',
          'repo': '[e-mail]:youruser/awesome_new_website.git',
          'branch': 'master',
          'backup_dir': '/home/awesome_new_website-dev/tmp/', # Used for mysql/psql dumps
          'db_name': 'awesome_new_website-dev',
          'db_username': 'awesome_new_website-dev',
          'domains': ['sitename-dev.agency.com', 'www.sitename.com'],
          'domains_redirect': [
              {'domain': 'sitename.com', 'destination_domain': 'www.sitename.com'},
          ],
          'ssl': True,
          'ssl_key_path': '../config/ssl.key', # This must be uploaded manually, possibly by a task in the future
          'ssl_cert_path': '../config/ssl.crt', # This must be uploaded manually, possibly by a task in the future
          'basic_auth': False,
          'basic_auth_path': '../config/htpasswd', # This must be uploaded manually, possibly by a task in the future
      },
  }

  add settings for stage/live as needed.

• call bin/fab --list for a list of commands

Note

when using these tasks, all project-specific tasks have to be decorated with the @task decorator from fabric.api.

Configuration file (config.ini)

Remember to add config.ini, example:

[static]

/media/ = py_src/project/media/

and/or

[static]

/static/ = %(static_files)s

Celery

The [celery] section has some special configuration parameters:

• version (default: empty): set the celery version. Other the value 3.1 is recognized and triggers the usage of the celery command instead of the django-celery based manage.py celeryd.

• app (default: project): the module that contains the celery.py (see the celery documentation)

Other options

[checkout]

tool = buildout (default)

tool = virtualenv

[celery] (if the section is present, celery is enabled)

[django]

base = .

base = project/

base = py_src/project (doesnt work with buildout yet, as it would try to access py_src/project/bin/django)

append_settings = true

append_settings = false

[static]

(see above)

/url-path/ = rel-path-filesystem/

[sendfile] /protected/media/ = ../upload/
