Puppet module for installing and managing python, pip, virtualenvs and Gunicorn virtual hosts.
Version 1.1.x Notes
Version 1.1.x makes several fundamental changes to the core of this module, adding some additional features, improving performance and making operations more robust in general.
Please note that everal changes have been made in v1.1.x which make manifests incompatible with the previous version. However, modifying your manifests to suit is trivial. Please see the notes below.
Currently, the changes you need to make are as follows:
- All pip definitions MUST include the owner field which specifies which user owns the virtualenv that packages will be installed in. Adding this greatly improves performance and efficiency of this module.
- You must explicitly specify pip => true in the python class if you want pip installed. As such, the pip package is now independent of the dev package and so one can exist without the other.
cd /etc/puppet/modules
git clone git://github.com/stankevich/puppet-python.git pythonInstalls and manages python, python-dev, python-virtualenv and Gunicorn.
version - Python version to install. Default: system default
pip - Install python-pip. Default: false
dev - Install python-dev. Default: false
virtualenv - Install python-virtualenv. Default: false
gunicorn - Install Gunicorn. Default: false
manage_gunicorn - Allow Installation / Removal of Gunicorn. Default: true
class { 'python':
version => 'system',
dev => true,
virtualenv => true,
gunicorn => true,
}
Installs and manages packages from pip.
ensure - present/latest/absent. Default: present
virtualenv - virtualenv to run pip in. Default: system (no virtualenv)
url - URL to install from. Default: none
owner - The owner of the virtualenv to ensure that packages are installed with the correct permissions (must be specified). Default: root
proxy - Proxy server to use for outbound connections. Default: none
environment - Additional environment variables required to install the packages. Default: none
egg - The egg name to use. Default: $name of the class, e.g. cx_Oracle
install_args - Array of additional flags to pass to pip during installaton. Default: none
uninstall_args - Array of additional flags to pass to pip during uninstall. Default: none
python::pip { 'cx_Oracle':
virtualenv => '/var/www/project1',
owner => 'appuser',
proxy => 'http://proxy.domain.com:3128',
environment => 'ORACLE_HOME=/usr/lib/oracle/11.2/client64',
install_args => ['-e'],
}
Installs and manages Python packages from requirements file.
virtualenv - virtualenv to run pip in. Default: system-wide
proxy - Proxy server to use for outbound connections. Default: none
owner - The owner of the virtualenv to ensure that packages are installed with the correct permissions (must be specified). Default: root
src - The --src parameter to pip, used to specify where to install --editable resources; by default no --src parameter is passed to pip.
group - The group that was used to create the virtualenv. This is used to create the requirements file with correct permissions if it's not present already.
python::requirements { '/var/www/project1/requirements.txt':
virtualenv => '/var/www/project1',
proxy => 'http://proxy.domain.com:3128',
owner => 'appuser',
group => 'apps',
}
Creates Python virtualenv.
ensure - present/absent. Default: present
version - Python version to use. Default: system default
requirements - Path to pip requirements.txt file. Default: none
proxy - Proxy server to use for outbound connections. Default: none
systempkgs - Copy system site-packages into virtualenv. Default: don't
distribute - Include distribute in the virtualenv. Default: true
owner - Specify the owner of this virtualenv
group - Specify the group for this virtualenv
index - Base URL of Python package index. Default: none
cwd - The directory from which to run the "pip install" command. Default: undef
timeout - The maximum time in seconds the "pip install" command should take. Default: 1800
python::virtualenv { '/var/www/project1':
ensure => present,

virtualenv - Run in virtualenv, specify directory. Default: disabled
mode - Gunicorn mode. wsgi/django. Default: wsgi
dir - Application directory.
bind - Bind on: 'HOST', 'HOST:PORT', 'unix:PATH'. Default: unix:/tmp/gunicorn-$name.socket or unix:${virtualenv}/${name}.socket
