When working with Ansible, one of the “recipes” that I always keep handy is related to debugging variables. I find it particularly useful to have a comprehensive view of the variables associated with a host, defined at the “facts”, environment, group, and host levels.

By setting gather_facts: true, we can access the variables through:

• Module: vars
• Environment: environment
• Group names: group_names
• Groups: groups
• Hosts: hostvars

To print the variables in a readable format, the to_nice_json filter can be used.
