registryUri in participant configuration file #130

Closed kocho1984 closed 3 weeks ago

Hi,

Is there a possibility to put registrUri in configuration file for the participant?

MariusBgm commented 1 month ago

Hi @kocho1984 , sure you can add it into the middleware section of the participant's configuration, see https://vectorgrp.github.io/sil-kit-docs/configuration/middleware-configuration.html For Example, the participantConfiguration.yaml would contain the following:

Middleware:
  RegistryUri: silkit://localhost:1234

@MariusBgm, is there any easy way to get IP and listening port of sil-kit-registry from IParticipantConfiguration? I have a config file with following entry and I would like to check in the code using SilKit API what IP and port is in the config.

Middleware:
  RegistryUri: silkit://55.55.55.55:8500

Hello @kocho1984, no this is not possible. The configuration itself is a 'black box' for the application that loads / or uses it.

If you don't mind me asking, what do you need the registry URI for?

kocho1984 commented 3 weeks ago

I would like to check if IP is available and listening on that port. I have to do that before creating a participant.

VDanielEdwards commented 3 weeks ago

The connection to the registry is attempted during the call to CreateParticipant. If the connection fails, eg., if it runs into a timeout, or whatever is listening on the port isn't 'speaking' the SIL KIt network protocol like a HTTP server, an exception is thrown which you could catch.

Additionally, SIL Kit will not just try to connect via TCP. At the moment we also attempt to connect via local-domain sockets using a 'predictable' name. But we might add further transports in the future, in addition to the existing ones.
