User Story: Bootstrap Python using ansible raw module

As a: UNIX and Linux system administrator

I want to:

  • automatically install the required python version on the system
  • Python 2 on RHEL 7 or older systems, supporting yum and selinux
  • Python 3 on RHEL 8 or Fedora, supporting dnf
  • Python 3 on Debian systems

So that: I can manage the system using Ansible.

Ansible Raw

Manually install python on your managed node

Install python using the OS package manager

Install python2 on RHEL 7, Python 3 on RHEL 8.

Install python
# On CentOS 7 or lower, Python 2 is required.
# yum and selinux bindings are only available with python 2
sudo yum install python

sudo dnf install python3

sudo apt-get update
sudo apt-get install python3

Automate python installation using Ansible raw
