hiera configuration
This module supports configuration through hiera. The following example creates two python3 virtualenvs. The configuration also pip installs a package into each environment.
python::python_pyvenvs:
"/opt/env1":
version: "system"
"/opt/env2":
version: "system"
python::python_pips:
"nose":
virtualenv: "/opt/env1"
"coverage":
virtualenv: "/opt/env2"
python::python_dotfiles:
"/var/lib/jenkins/.pip/pip.conf":
config:
global:
index-url: "https://mypypi.acme.com/simple/"
extra-index-url: "https://pypi.risedev.at/simple/"
Using SCL packages from RedHat or CentOS
To use this module with Linux distributions in the Red Hat family and python distributions from softwarecollections.org, set python::provider to 'rhscl' and python::version to the name of the collection you want to use (e.g., 'python27', 'python33', or 'rh-python34').
Release Notes
Version 1.9.8 Notes
The pip
, virtualenv
and gunicorn
parameters of Class['python']
have changed. These parameters now accept absent
, present
and latest
rather than true
and false
. The boolean values are still supported and are equivalent to present
and absent
respectively. Support for these boolean parameters is deprecated and will be removed in a later release.
Version 1.7.10 Notes
Installation of python-pip previously defaulted to false
and was not installed. This default is now true
and python-pip is installed. To prevent the installation of python-pip specify pip => false
as a parameter when instantiating the python
puppet class.
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 several 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.
