I am implementing a new module for specific needs in my environment. I would like to print certain outputs (such as some variables) by this module, similar as debug module prints with msg parameter, but in a more customized way.
AnsibleModule class has fail_json() method which accepts msg argument to print on a failure, but I cannot find a way to print a message on success with exit_json()
I also don't know how builtin debug module works, found almost nothing except DOCUMENTATION and EXAMPLES in the module script.
