I've never set vars inside the playbook but I've seen it done. I'm not
really a fan of that structure because different applications/environments
might use the same role and having the vars set within the playbooks can
cause a lot of problems or unintended consequences.
Without know your entire infrastructure it's difficult to answer but I
specify variables in three separate locations
1. <rolename>/defaults/main.yml
2. <appname>/group_vars
3. <appname>/host_vars
Ansible is quite flexible with its handling of variables and allows them to
be specified in many different locations.
