• ANSIBLE_CONFIG (environment variable): If the ANSIBLE_CONFIG environment variable is set, Ansible will use the file specified by this variable.
• ansible.cfg (in the current directory): If no environment variable is set, Ansible will look for a file named ansible.cfg in the directory where the Ansible command is run.
• .ansible.cfg (in the home directory): If no configuration file is found in the current directory, Ansible will look for a file named .ansible.cfg in the home directory of the user running the command.
• /etc/ansible/ansible.cfg: As a last resort, Ansible will use the global configuration file located at /etc/ansible/ansible.cfg.
