Python 3 Support

Ansible 2.2 features a tech preview of Python 3 support. This topic discusses how you can test to make sure your modules and playbooks work with Python 3.

Testing Python 3 with commands and playbooks

• Install Ansible 2.2+

• To test Python 3 on the controller, run your ansible command via python3. For example:

  $ python3 /usr/bin/ansible localhost -m ping
  $ python3 /usr/bin/ansible-playbook sample-playbook.yml
  

Testing Python 3 module support

• Set the ansible_python_interpreter configuration option to /usr/bin/python3. The ansible_python_interpreter configuration option is usually set per-host as inventory variable associated with a host or set of hosts. See the inventory documentation for more information.

• Run your command or playbook.:

  $ ansible localhost -m ping
  $ ansible-playbook sample-playbook.yml
  

Note that you can also use the -e command line option to manually set the python interpreter when you run a command. For example:

$ ansible localhost -m ping -e 'ansible_python_interpreter=/usr/bin/python3'
$ ansible-playbook sample-playbook.yml -e 'ansible_python_interpreter=/usr/bin/python3'
