Configuration ============= Magnum has a number of configuration options which will be detailed here. Magnum Config ------------- The magnum configuration file is called ``magnum.conf``. Magnum Pipeline --------------- The pipeline details are contained in ``api-paste.ini``. Healthcheck Middleware ~~~~~~~~~~~~~~~~~~~~~~ This piece of middleware creates an endpoint that allows a load balancer to probe if the API endpoint should be available at the node or not. The healthcheck middleware should be placed early in the pipeline. Which is located in your ``api-paste.ini`` under a section called ``[filter:healthcheck]``. It should look like this:: [filter:healthcheck] paste.filter_factory = oslo_middleware:Healthcheck.factory backends = disable_by_file disable_by_file_path = /etc/magnum/healthcheck_disable The main pipeline using this filter should look something like this also defined in the ``api-paste.ini``:: [pipeline:main] pipeline = cors healthcheck request_id authtoken api_v1 If you wish to disable a middleware without taking it out of the pipeline, you can create a file under the file path defined by ``disable_by_file_path`` ie. ``/etc/magnum/healthcheck_disable``. For more information see `oslo.middleware `_.
