Ansible can also use configuration templates just fine. It can also support secrets management, depending on how you want to store the secrets. The first tool covered in the series itself was Credstash (https://tozny.com/blog/crypto-tools-for-devops-credstash/). Ansible supports retrieving secrets from Credstash natively, either for use in commands or when populating templates: http://docs.ansible.com/ansible/playbooks_lookups.html#the-c...
Git-crypt is but one solution for storing secrets _next to_ the code that uses them. Credstash is another for storing secrets in another, server-accessible location. Both can work with tools like Ansible (or Puppet or Chef or Salt).
From the tone of the above (and your other responses) you're not a heavy Ansible user. That's fine. Use the tool you're comfortable with. But don't try to turn people away from an equally useable alternative to something you _do_ use just because it's not your tool of choice.
