Deploy lavalink on heroku.

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:

<-- Click me!

Buildpacks should be added automatically, you may modify the PASS variable during setup to change the password.

Github Deploy:

1. Create a fork of this repo
2. Navigate to your heroku project @dashboard.heroku.com
3. 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.
4. 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.
5. In the same menu, create a var called APP_NAME and set it to your heroku applications name.
6. Navigate to the "Deploy" tab
7. Find/Click the "Connect to GitHub" section and login if needed
8. For the repo name, type "heroku-lavalink" and Click "Search"
9. Click "Connect"
10. Scroll down and find "Manual Deploy", then switch the branch to auto and "Deploy Branch".

Heroku CLI Deploy:

1. Download files (Clone or download->Download ZIP).
2. Extract files into an empty directory.
3. 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.
4. 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.
5. 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.
6. In the same menu, create a var called APP_NAME and set it to your heroku applications name.

Notes:

1. After changing PASS you must redeploy or click the More menu and restart all dynos.
2. 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.

Since this evening, I've been getting the following error in Heroku logs:

port?

what do i enter the port of the lavalink as?

Attempt to decode JSON with unexpected mimetype: text/html; charset=utf-8

error just at title.

I use lavapy to use lavalink, and I get this error.
But I use repl-lavalink, I don't get this error.

read ECONNRESET

Unfortunately, i can't use the server. There are no errors during bootstrap but when I tried connecting my lava manager (I use erela.js btw), it shows this error:

Node "disgusting-bot.herokuapp.com" encountered an error: read ECONNRESET.

is there any way to fix this?

Running it for an estimated 24 hours now, and Heroku fired an error, apparently I've exceeded the maximum RAM limit

How to connect lavalink server with discord.py bot

Describe the bug
This ain't a bug, but a question. I'm trying to upload my discord.py bot to heroku, and i use lavalink for playing music. And for connecting to the server, I need "host", "port" and "rest_uri".
When having the bot and server running in my PC, I would go host = 127.0.0.1, port = 2333, rest_uri=http://127.0.0.1:2333
But I have no idea on how to do it with the server on heroku.

Deployment Method
The deployment method used:

1. One Click Deploy
