Checking if services work

This playbook can perform a check to ensure that you've configured things correctly and that services are running.

To perform the check, run:

ansible-playbook -i inventory/hosts setup.yml --tags=self-check

The shortcut command with just program is also available: just run-tags self-check

If it's all green, everything is probably running correctly.

Besides this self-check, you can also check whether your server federates with the Matrix network by using the Federation Tester against your base domain (example.com), not the matrix.example.com subdomain.
