Configuration¶

The server configuration is done in application.yml. You can find an example below.

Example application.yml¶

application.yml

server: # REST and WS server
  port: 2333
  address: 0.0.0.0
  http2:
    enabled: false # Whether to enable HTTP/2 support
plugins:
#  name: # Name of the plugin
#    some_key: some_value # Some key-value pair for the plugin
#    another_key: another_value
lavalink:
  plugins:
#    - dependency: "com.github.example:example-plugin:1.0.0" # required, the coordinates of your plugin
#      repository: "https://maven.example.com/releases" # optional, defaults to the Lavalink releases repository by default
#      snapshot: false # optional, defaults to false, used to tell Lavalink to use the snapshot repository instead of the release repository
#  pluginsDir: "./plugins" # optional, defaults to "./plugins"
#  defaultPluginRepository: "https://maven.lavalink.dev/releases" # optional, defaults to the Lavalink release repository
#  defaultPluginSnapshotRepository: "https://maven.lavalink.dev/snapshots" # optional, defaults to the Lavalink snapshot repository

Alternatively, you can also use environment variables to configure the server. The environment variables are named the same as the keys in the application.yml file, but in uppercase and with . replaced with _. For example, server.port becomes SERVER_PORT. For arrays, the index is appended to the key, starting at 0. For example, LAVALINK_PLUGINS_0_DEPENDENCY refers to the dependency key of the first plugin.
