2 # =======================================================
3
4 # Nearly all parameters can be overridden in ansible-playbook
5 # or with command line flags. Ansible will read ANSIBLE_CONFIG,
6 # ansible.cfg in the current working directory, .ansible.cfg in
7 # the home directory, or /etc/ansible/ansible.cfg, whichever it
8 # finds first
9
10 # For a full list of available options, run ansible-config list or see the
11 # documentation: https://docs.ansible.com/ansible/latest/reference_appendices/config.html.
