• ALERTS_FILE_PATH: /etc/prometheus/ Set the path of the Prometheus rules inside the container.

• AUTO_GENERATE_ALERT: 'True' Auto generate rules to every docker service which non defined in the scaling_policy file. (True/False)

• DEFAULT_SCALEUP: 90 The scale up parameter for the auto generated rules if AUTO_GENERATE_ALERT is True.

• DEFAULT_SCALEDOWN: 10 The scale down parameter for the auto generated rules if AUTO_GENERATE_ALERT is True.

• PROMETHEUS: localhost The address of Prometheus.

Volumes

The generator needs the following volumes:

• /var/run/docker.sock:/var/run/docker.sock The host docker socket for list docker services.

• /var/lib/micado/alert-generator/:/var/lib/micado/alert-generator/ For the input scaling policy file.
