We use AAP to deploy roles. The roles are in Git.
I now have 2 roles that need to deploy the same files and templates, and of course I don't want to keep 2 versions in Git.
How could I solve that?
Is it possible that the files and templates could (should?) be part of separate role that you perhaps pull in as dependency?
The other pattern I saw out there was that the file/template wasn't part of the roles, but was instead provided by playbook that is using the roles. So file was in repository with playbook and template/file path was passed to role as parameter.
As an alternative to what @mea_rah proposed, you can also push your files in a git repository that you can clone/pull on your remote hosts (or locally, then copied / templated out, if needed) from a separate task, which can be in or out (via include_tasks or import_tasks modules) of your roles. Or if all target hosts have access to a shared storage, you can directly copy files from there, depending on your needs.
I still think having your files and deploy task on a separate role used as a dependency for your other roles is the way to go, though I'd need more context to give you a more appropriate answer.
