Ansible – Enable logging

By default, Ansible logs the output of playbooks to the standard output only. In order to enable logging to a file for later review or auditing, it can be turned on by setting log_path to a path location where Ansible has a write access.

In my case, i have added the “log_path” setting in the ansible configuration file “/etc/ansible/ansible.cfg” –

1
2
# grep log_path /etc/ansible/ansible.cfg
log_path = /var/log/ansible.log

Now I can view the log file to all the details on ansible runs –

It logs dry-runs (–check) as well and it is smart enough not to log Password arguments.
