Python compatibility between controller and managed nodes

[Gaétan QUENTIN@Work]

Hi,

 A question about python compatibility between controller and managed node.


 Do an ansible controller 2.9.XX with python 2.7.X can manage nodes
where python 3.8 is installed?

 The answer is not clear here:
https://docs.ansible.com/ansible/latest/reference_appendices/python_3_support.html


Regards

yes. There is no relation between the Python versions on controller and
target (except that both have to be supported by Ansible).

thank you for this response.


in my comprehension, ansible controller push some python code onto the
target and this code is executed on the target.


does that mean that a 3.8 target recognize 2.7 code (we all know there
is a compatibility rupture between 2.7 and 3.X) and can execute 2.7 code
without problem?

is there an official documentation about that ?

the code pushed is from modules and module_utils, which are coded to
be compatible with the widest range of python versions.
You could also write modules in other languages (and people have in
perl/ruby/bash/golang/etc) and use ansible to execute them, the code
on the controller really does not have to match with the code
executing on remotes.
