When you’re starting hosts from scratch, you can avoid preinstalling python in your image or startup scripts by issuing a raw command in the pre_tasks section. This doesn’t require python to be available on the remote host, effectively bootstrapping it to continue with the playbook. Here’s an example for debian-based hosts: - hosts: my_host remote_user: my_user become: yes gather_facts: false pre_tasks: — name: Bootsrap Python2 for Ansible raw: bash -c “test -e /usr/bin/python || (apt -qqy update && apt install -qqy python-minimal)” register: output changed_when: output.stdout != “” — name: Gathering Facts setup: # Also known as gather_facts
