python

Installs and manages python, python-dev, python-virtualenv and gunicorn.

Examples

install python from system python
class { 'python':
  version    => 'system',
  pip        => 'present',
  dev        => 'present',
  virtualenv => 'present',
  gunicorn   => 'present',
}
install python3 from scl report
class { 'python' :
  ensure      => 'present',
  version     => 'rh-python36-python',
  dev         => 'present',
  virtualenv  => 'present',
}

Parameters

The following parameters are available in the python class.

ensure

Data type: Enum['absent', 'present', 'latest']

Desired installation state for the Python package.

Default value: $python::params::ensure

version

Data type: Any

Python version to install. Beware that valid values for this differ a) by the provider you choose and b) by the osfamily/operatingsystem you are using. Allowed values:

  • provider == pip: everything pip allows as a version after the 'python=='
  • else: 'system', 'pypy', 3/3.3/...
    • Be aware that 'system' usually means python 2.X.
    • 'pypy' actually lets us use pypy as python.
    • 3/3.3/... means you are going to install the python3/python3.3/... package, if available on your osfamily.

Default value: $python::params::version
