K2HR3 OpenStack Notification Listener To Japanese

K2HR3 OpenStack Notification Listener (k2hr3_osnl) is a program to synchronize the information of OpenStack instances with K2HR3. Here is the data synchronization flow.

  • When booting an instance
    • cloud-init will add the instance information to K2HR3
  • When deleting an instance
    • k2hr3_osnl will delete the information from K2HR3

Here is how k2hr3_osnl works in details::

  • OpenStack nova and neutron emit the deleted instance information to a message queue server.
  • k2hr3_osnl receives the deleted instance information from the message queue server.
  • The information contains the instance unique id, the hostname and the IP address of the deleted instance.
  • k2hr3_osnl invokes K2HR3 RESTful HTTP API with the request parameters that contains the deleted instance information.
  • K2HR3 will delete the instance information.

See the https://k2hr3-osnl.readthedocs.io/en/latest/usage.html for details.
