Docker

LiveKit is published to Docker Hub under livekit/livekit-server

Running

Creating API keys

LiveKit utilizes JWT based access tokens for authentication to all of its APIs. Because of this, the server needs a list of valid API keys and secrets to validate the provided tokens. For more, see Access Tokens guide.

Generate API key/secret pairs with:

./bin/livekit-server generate-keys

or

docker run --rm livekit/livekit-server generate-keys

Store the generate keys in a YAML file like:

Starting the server

In development mode, LiveKit has no external dependencies. You can start LiveKit by passing it the keys it should use in LIVEKIT_KEYS. LiveKit could also use a config file or config environment variable LIVEKIT_CONFIG
