This service is currently used for a single reason: generate JWT tokens with a given identity for a given room, so that users can use them to authenticate against LiveKit SFU.
To start the service locally:
$ LIVEKIT_URL="ws://somewhere" LIVEKIT_KEY=devkey LIVEKIT_SECRET=secret go run *.go
The listening port is configurable via the LK_JWT_PORT environment variable and defaults to 8080.
For testing and debugging (e.g., in the absence of trusted certificates while testing in a lab) you can disable TLS verification for outgoing matrix client connection by setting the environment variable LIVEKIT_INSECURE_SKIP_VERIFY_TLS to YES_I_KNOW_WHAT_I_AM_DOING.
