Configuration

The service allowed two variant of configuration:

1. use the Configurator service

2. use the configuration file

The service reads settings from the configuration file by default.

You can specify the –luna-config option for pulling settings from the Configurator service, see configurator.

Auto reload configuration

The service supports an auto-reload of configurations. You can enable this feature by specifying a config-reload option in the command line. The service periodically checks new settings. If current settings and new pulled settings are the same the service will not perform any actions. You can specify the check period in the pulling-time command line argument (10 seconds by default).

If a configuration fetching has failed, the service will work without applying any changes to the existing configurations.

If check connections with the new configuration have failed, the service will retry pulling new configuration after pulling-time seconds. The service will shut down after 10 failed attempts.

Warning

Service can work incorrectly while the new settings are being applied. It is strongly recommended not to send requests to the service when you change important settings (database credentials, work plugins list, and others).
