Machine Registration Container
******************************

The machine registration container is responsible for the following functions:

* Registering new test machines:

  * Creating tags for the test machine without manual intervention, with the
    help of :doc:`gfxinfo`;
  * Finding out which TTY device is connected to the gateway's :doc:`salad`
    service;

* Verifying that the state of the test machine matches the state found in
  :ref:`MarsDB`, including verifying that the serial console
  is talking to the gateway;

* Verifying that the test machine has the wanted list of tags, and hiding the
  hardware that is not needed for testing (useful for multi-GPU setups).

Find out more about it in the
:download:`source code <../../machine_registration/machine_registration.py>`.
