An Ansible role to download and install Python from source

Ansible role: source-python

An Ansible role to download and install Python from source. Supported distributions are the currently maintained releases of the Red Hat family and derivatives, and Ubuntu. At this time tests are run on Rocky Linux 9, Rocky Linux 8, CentOS Stream 9, CentOS Stream 8, CentOS 7, Fedora 37, Fedora 36, Fedora 35, Ubuntu 22.04, Ubuntu 20.04 and Ubuntu 18.04.

Requirements

None.

Role Variables

The variables that control the role behaviour are listed below with their respective defaults:

python_install_dir: /opt

The base directory of the installation

python_release: 3.10.0

The version of Python to be installed, in x.y.z form.

python_user: python

The owner of the installation.

python_group: python

The installation group.

python_src_dir: /sw/python

The directory where the source archive is downloaded, extracted and built.

python_force: false

When true installation is performed even if a bug fix release of the same minor version was already installed. Useful to repeat installations after something went wrong or to perform upgrades. Note that setting python_force to true breaks the role's idempotence.

Dependencies

None.

Example Playbook

- hosts: servers
  roles:
     - role: nmusatti.source_python
       vars:
         python_release: 3.10.0

Note the underscore in the name. Ansible Galaxy did not accept my submission otherwise.

source-python's Issues

No SSL module - pip fails

By default, when I ran this playbook on CentOS 7, it worked nicely but resulted in an installation with broken pip. The reason was, openssl-devel has not been installed in the system, so ./configure has built Python without OpenSSL, and pip failed.

After yum install openssl-devel, I had a working installation with pip.

I suggest adding this package and its Debian counterpart to the "Install dependencies" step.
