For an actual deployment example, please look into my deployment repository.
The Heroku filesystem is ephemeral, which means files written to the file system will be destroyed when the server is restarted.
You will have to set a DropBox auth token to synchronize your world information with:
$ heroku config:set DROPBOX_API_TOKEN="MY_DROPBOX_TOKEN"
You need to set a ngrok auth token to open secure tunnel to your minecrfat server:
$ heroku config:set NGROK_API_TOKEN="MY_NGROK_TOKEN"
You can customize ngrok by setting the
NGROK_OPTS config variable. For example:
$ heroku config:set NGROK_OPTS="-subdomain=my-subdomain"
You can choose the Minecraft version by setting the MC_VERSION like so:
$ heroku config:set MC_VERSION="1.10.2"
You can also configure the server properties by creating a
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
whitelist.json to your Git repository and the Minecraft server will pick them up.
Copy the snippet above into CLI.
