heroku-lavalink
Easily deploy a lavalink server on heroku. This approach is minimal, but reliable. This branch will automatically download the latest Lavalink jar file.
-
heroku-lavalink will now download the latest Lavalink.jar automatically & directly from GitHub
To update your Lavalink.jar, restart all dynos.
-
heroku-lavalink can now visit itself every 20 minutes (instead of uptimerobot)
set APP_NAME in config vars to your heroku application's name to enable, you only need this for the free tier
Your lavalink server will be available over port 80 and 443(HTTPS/SSL) at your heroku app website (APP_NAME.herokuapp.com)
I will not provide support in issues for external libraries.
| Config Var | Description | Default |
|---|---|---|
| PASS | The password you will use to authenticate http requests. Change this to whatever you want it to be. | youshallnotpass |
| APP_NAME | Set this to your heroku application's name. This will allow the project to visit itself and prevent it from sleeping. | blank |
| PRERELEASES | Whether to download lavalink prereleases. | false |
| GITHUB_REPO | The github repo to fetch releases from. | freyacodes/Lavalink |
| JAVA_TOOL_OPTIONS | This sets the ram to max. Don't edit this variable unless you know what you're doing. | -Xmx400m -Xms400m -XX:MaxPermSize=48m |
One Click Deploy:
Buildpacks should be added automatically, you may modify the PASS variable during setup to change the password.
Github Deploy:
- Create a fork of this repo
- Navigate to your heroku project @dashboard.heroku.com
- Navigate to your project "Settings", click "Reaveal Config Vars", and create a new var called PASS and set it to what you want your lavalink password to be.
- In the same menu, create a new var called JAVA_TOOL_OPTIONS and set it to
-Xmx400m -Xms400m -XX:MaxPermSize=48m. You may also set other config vars here. - In the same menu, create a var called APP_NAME and set it to your heroku applications name.
- Navigate to the "Deploy" tab
- Find/Click the "Connect to GitHub" section and login if needed
- For the repo name, type "heroku-lavalink" and Click "Search"
- Click "Connect"
- Scroll down and find "Manual Deploy", then switch the branch to auto and "Deploy Branch".
Heroku CLI Deploy:
- Download files (Clone or download->Download ZIP).
- Extract files into an empty directory.
- Follow https://devcenter.heroku.com/articles/git. If heroku is unable to automatically configure buildpacks, go to your projects settings on the heroku website and add java and nodejs.
- Go to your project settings->config vars on heroku and set a new var called PASS to what you want your lavalink password to be.
- In the same menu, create a new var called JAVA_TOOL_OPTIONS and set it to
-Xmx400m -Xms400m -XX:MaxPermSize=48m. You may also set other config vars here. - In the same menu, create a var called APP_NAME and set it to your heroku applications name.
Notes:
- After changing PASS you must redeploy or click the More menu and restart all dynos.
- If heroku is unable to automatically configure buildpacks, go to your projects settings on the heroku website and add java and nodejs.
Please understand your lavalink server will likely run out of memory on a free dyno. I would recommend upgrading or switching to a lighter alternative. If you do upgrade, you must change -Xmx in the JAVA_TOOL_OPTIONS to your new amount of ram.
