Docker

Docker images can be found under packages with old builds prior to v3.7.4 being available on Docker Hub. There are 2 image variants Ubuntu and Alpine, the Alpine variant is smaller and can be used with the -alpine suffix, for example ghcr.io/lavalink-devs/lavalink:3-alpine.

Install Docker & Docker Compose

Create a docker-compose.yml with the following content:

docker-compose.yml

version: "3.8"

services:
  lavalink:
    # pin the image version to Lavalink v4
    image: ghcr.io/lavalink-devs/lavalink:4
    container_name: lavalink
    restart: unless-stopped
    environment:
      # set Java options here
      - _JAVA_OPTIONS=-Xmx6G
      # set lavalink server port
      - SERVER_PORT=2333
      # set password for lavalink
      - LAVALINK_SERVER_PASSWORD=youshallnotpass
    volumes:
      # mount application.yml from the same directory or use environment variables
      - ./application.yml:/opt/Lavalink/application.yml
      # persist plugins between restarts, make sure to set the correct permissions (user: 322, group: 322)
      - ./plugins/:/opt/Lavalink/plugins/
    networks:
      - lavalink
    expose:
      # lavalink exposes port 2333 to connect to for other containers (this is for documentation purposes only)
      - 2333
    ports:
      # you only need this if you want to make your lavalink accessible from outside of containers
      - "2333:2333"
networks:
  # create a lavalink network you can add other containers to, to give them access to Lavalink
  lavalink:
    name: lavalink

Create an application.yml file in the same directory as the docker-compose.yml file. (Example here) or use environment variables (Example here)

Run docker compose up -d. See Docker Compose Up

If your bot also runs in a docker container you can make that container join the lavalink network and use lavalink (service name) as the hostname to connect. See Docker Networking & Docker Compose Networking
