Self hosted Minecraft Bedrock Server in TrueNAS Scale

 We will host a docker container in TrueNAS Scale that runs the minecraft bedrock dedicated server. I apologize for the gap below; I wanted to preserve the original resolution of the pictures to display the text clearly.

First go to the TrueNAS Scale UI, typically located at http://truenas.local/ and click Apps then click "Discover Apps". 

Click "Custom App"

Enter the following in the fields.

For "Node Port", choose the port you want people to use when they connect to your server. For "Host Path", create a folder and choose that as the location to store your database files.

Leave the rest of the fields as default, and click the "Install" button at the bottom. With the above screenshotted configurations, we now have a Minecraft Bedrock server hosted at port 12345. If your truenas scale server's local IP is 192.168.0.5 for example, then you would use 192.168.0.5:12345 as your server address to connect to in Minecraft. You can use port forwarding to expose this to the internet with your public IP instead. If you want to get really fancy, you can buy a domain and have its A record point to your home IP address, that way you can have people connect through myserver.com:12345 instead.
