The debops.etckeeper Ansible role will install etckeeper, which puts the /etc directory under version control. To do this, etckeeper hooks into the package management and from now on automatically will commit changes to a local git repository under /etc/.git/ directory. This makes it easy to see which changes are applied on a specific host and quickly revert them, if something breaks.

The role will install a special Ansible local fact which will commit any changes in the /etc directory as well, usually at the moment the Ansible facts are gathered.
