gabops.python

Installs Python from source code.

Requirements

None.

Role Variables

Variable	Default value	Description
python_version	3.8.1	Defines the Python version to be installed.
python_source_installation_path	/opt/Python/source/3.8.1	Defines the path where the source code will be installed.
python_custom_installation_path	""	Defines a custom installation path to install Python in. Note that this parameter is not required. See Notes.
python_build_requirements	""	Defines the list of packages to be installed in order to build the source code. Note that this role handles its own list of packages already, however, this options exists for allowing you to define your own list of packages if required.
python_install_build_requirements	true	Defines if the role should install building requirements (the internal or the ones specified by you in `python_build_requirements`).
python_configure_parameters	['--with-ensurepip=install']	Defines the list of parameters to be passed to the `./configure` script.
python_make_target	altinstall	Defines the make target. I strongly recomend to avoid to change this value unless you know what you are doing otherwise you can break your system.

Notes:

As you can see, the default value for python_make_target is altinstall. This means that by default Python will be installed in /usr/local/lib/Python* and the binary in /usr/local/bin/python*. For changing this behaviour and installing Python in the directory defined in python_custom_installation_path you can use for example:

python_custom_installation_path: /opt/installations/python3

python_configure_parameters:
  - --with-ensurepip=install
  - --prefix={{ python_custom_installation_path }}"

python_make_target: install

Bare in mind that with the configuration in the example you will need to configure the PATH environment variable in order to add /opt/installations/python3/bin to it.

Dependencies

None.

Example Playbook

Simple installation:

- hosts: servers
  roles:
    - role: gabops.python

Or go crazy with several Python versions:

- hosts: servers
  tasks:
    - name: Install Python
      include_role:
        name: gabops.python
      vars:
        python_version: "{{ item.version }}"
        python_installation_path: "{{ item.path }}"
      loop:
        - version: 3.8.1
          path: /opt/Python/3.8.1

        - version: 3.7.6
          path: /opt/Python/3.7.6
