Puppet Class: st2::profile::python

Inherits:
st2
Defined in:
manifests/profile/python.pp

Summary

StackStorm compatable installation of Python and dependencies.

Overview

include st2::profile::python

Examples:

Basic Usage

include st2::profile::python

Install with python 3.6 (if not default on your system)

$st2_python_version = $facts['os']['family'] ? {
  'RedHat' => '3.6',
  'Debian' => 'python3.6',
}
class { 'st2':
  python_version            => $st2_python_version,
  python_enable_unsafe_repo => true,
}

Parameters:

  • version (String) (defaults to: $st2::python_version) —

    Version of Python to install. Default is ‘system’ meaning the system version of Python will be used. To install Python 3.6 on RHEL/CentOS 7 specify ‘3.6’. To install Python 3.6 on Ubuntu 16.05 specify ‘python3.6’.

  • enable_unsafe_repo (Boolean) (defaults to: $st2::python_enable_unsafe_repo) —

    The python3.6 package is a required dependency for the StackStorm ‘st2` package but that is not installable from any of the default Ubuntu 16.04 repositories. We recommend switching to Ubuntu 18.04 LTS (Bionic) as a base OS. Support for Ubuntu 16.04 will be removed with future StackStorm versions. Alternatively the Puppet will try to add python3.6 from the 3rd party ’deadsnakes’ repository: launchpad.net/~deadsnakes/+archive/ubuntu/ppa. Only set to true, if you are aware of the support and security risks associated with using unofficial 3rd party PPA repository, and you understand that StackStorm does NOT provide ANY support for python3.6 packages on Ubuntu 16.04. The unsafe PPA ‘’ppa:deadsnakes/ppa’‘ launchpad.net/~deadsnakes/+archive/ubuntu/ppa can be enabled if you specify `true` for this parameter. (default: `false`)
