I am struggling to find a reasonable method to detect which of
python3-pip I should install depending on the contents of the
ansible_python fact. This is on Debian and Ubuntu.
ansible_python contents, I did not see anything that would let me correlate the Python version Ansible uses with the package name used to install that Python version. So even though I could glean the path to the Python executable from the fact I don't see how to determine the package used to install it.
The rationale is trying to avoid hardcoding stuff into my playbook. But failing everything else I'd also be willing to hardcode these assumptions into my playbook. The "best" I've come up with so far was to use the
package_facts module to collect the information on installed packages, then use
ansible_python.version.major to pick from either
python3-pip, which still contains the assumptions: 1.) that
ansible_python.version.major==2 maps to
ansible_python.version.major==3 maps to
python3-pip and 2.) that
ansible_python.executable does name either of the packaged Python versions available in the
python3 packages respectively.
Is there an objectively better way? Better isn't meant to elicit opinions here, anything getting rid of the implied assumptions qualifies as objectively better.
