+#   login_host: "mysql.example.org"
+#   login_user: "root"
+#   login_password: "super-secure-password"

+# databases:
+#   reports:
+#     state: "present"
+#     encoding: "{{ DEFAULT_ENCODING }}"
+#     <<: *default_connection
+#   application:
+#     state: "present"
+#     encoding: "{{ DEFAULT_ENCODING }}"
+#     <<: *default_connection
