Ansible - Bootstrap python
When you’re starting hosts from scratch, you can avoid preinstalling python in your image or startup scripts by issuing a
raw command in ansible in a
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
gather_facts is set to false since some advanced facts require running python code on the remote host, hence we disable it in the beginning and then re-run it using
