This is a Heroku Buildpack for running a Minecraft server in a dyno.
Create a free ngrok account and copy your Auth token. Then create a new Git project with a eula.txt
file:
$ echo 'eula=true' > eula.txt
$ git init
$ git add eula.txt
$ git commit -m "first commit"
Then, install the Heroku toolbelt. Create a Heroku app, set your ngrok token, and push:
$ heroku create
$ heroku buildpacks:add heroku/jvm
$ heroku buildpacks:add https://github.com/VigroX/heroku-buildpack-mcserver
$ heroku config:set NGROK_API_TOKEN="xxxxx"
$ heroku config:set DROPBOX_API_TOKEN="xxxxx"
$ git push heroku master
Finally, open the app:
$ heroku open
This will display the ngrok logs, which will contain the name of the server (really it's a proxy, but whatever):
Server available at: 0.tcp.ngrok.io:17003
Copy the 0.tcp.ngrok.io:17003
part, and paste it into your local Minecraft app
as the server name.
The buildpack will sync your world to the bucket every 60 seconds, but this is configurable by setting the AWS_SYNC_INTERVAL
config var.
The Minecraft server runs inside a screen
session. You can use Heroku Exec to connect to your server console.
Once you have Heroku Exec installed, you can connect to the console using
$ heroku ps:exec
Establishing credentials... done
Connecting to web.1 on ⬢ lovely-minecraft-2351...
$ screen -r minecraft
WARNING You are now connected to the Minecraft server. Use Ctrl-A Ctrl-D
to exit the screen session.
(If you hit Ctrl-C
while in the session, you'll terminate the Minecraft server.)
You can customize ngrok by setting the NGROK_OPTS
config variable. For example:
$ heroku config:set NGROK_OPTS="--remote-addr 1.tcp.ngrok.io:25565"
You can choose the Minecraft version by setting the MINECRAFT_VERSION like so:
$ heroku config:set MINECRAFT_VERSION="1.8.9"
You can also configure the server properties by creating a server.properties
file in your project and adding it to Git. This is how you would set things like
Creative mode and Hardcore difficulty. The various options available are
described on the Minecraft Wiki.
You can add files such as banned-players.json
, banned-ips.json
, ops.json
,
whitelist.json
to your Git repository and the Minecraft server will pick them up.
