Hi! I love this!
Iām having issues increasing the RAM usage though. Iām using a Raspberry Pi 4 (4GB). Iāve created an Environmental Variable of DOUBLE_RAM and set it to TRUE. However, every time I start my server it says āStarting jar file with: 1G of RAMā. I also get a lot of warnings that the server is overloaded and canāt keep up.
Any thoughts?
@ate4110 welcome to the forum! To prevent anyone asking me to make a var which sets a much bigger amount of RAM i deleted the old one and made a completely new system for the RAM: https://github.com/AlexProgrammerDE/balena-minecraft-server#custom-ram-optional-link
Awesome! Sorry for the noob question, but where do I change that value?
Create a variable like the DOUBLE_RAM variable.

So, for example, I would create a variable called āRAMā and set the value to ā2GBā? Is the syntax correct? Is this an environmental variable?
Thank you so much for the help
The value should be 2G . And yes its an enviromental variable.
Hi there! 
This is truly amazing, but I have one question.
How does one OP himself and/or other players?
Thanks in advance.
I ran into that problem myself last night.
make sure your mc-server/serverfiles/server.properties has these 3 lines:
rcon.port=25575
enable-rcon=true
rcon.password=balena
if you have already spun up your server you can edit the server properties using winscp/filezilla
if you do modify the server.properties file remember to restart the mc-server
Join the game on your minecraft server then while still connected use an RCON program as described here
the command you will need to send is:
op your-minecraft-username
Thank you sir!
This worked for me.
Iāve followed these instructions, made my pi use 3gb of ram for the server, yet it still states itās overloaded and on top of that I canāt find the server on any lan connected devices, any ideas?
I am trying to be able to play worldwide following the instructions on the GitHub page but wen I try to open the port on my tp-link router it asks me for a āExternal Service Portā that I donāt know were to get.
Can some one help me?
Hi there! First of all, thanks soo much for creating this project! Iāve been looking for an easy way to setup a Dedicated Minecraft server on my Raspberry Pi 4 (8GB) for ages, and this is the first method that seems to be ridiculously easy to use.
Iāve gotten as far as getting the default project to run on my server, but I need to use Forge 1.12.2, which of course requires Java-8 rather than 11. Furthermore, Iāve noticed that the system seems to be hard-coded to use the latest vanilla jar files and paper.
Are there any Device Service variables I could use to specify the JDK and jar file to be used?
I am attempting to experiment with ways to do this in the meantime, but any help on the matter would be welcome.
Thanks in advance!
You can set JAR_FILE to use a specific file.
I also had problem with 8GB raspi4, but worked like a charm with the 4GB version.
looks like there is an issue to find a proper image for a 8GB raspi4.
Here is the failed build log:

Thanks for a great project. Forced me to learn balena and give up the idea to proceed with ansible 
ā¦ Enjoying it with my kids now ā¦ One question: did you think of some world backup procedure ? Balena does not offer it out of the box. And knowing how unreliable raspi on SD is the idea of losing our world is haunting me ā¦ Would be grateful for any advice. Since iām new to minecraft game/servers at least telling which files I need to backup would help a lot Iāll google for paper server backup procedures for now

Purchased EasyBackup Psper Server plugin, backups to Dropbox like a charm ā¦ didnāt try restoring though. :):) Hopefully that will work too
I too would be interested in this. We started of with my boys, using 1.15.2. When the clients upgraded to 1.16 I was forced to reinstall everything from scratch to the RPi4 as I found no means to save - if it was possible at all. Obviously this felt the boys sad, but we restarted.
Now I am wondering how to restart a new map? And is it possible to use a seed for a new map.
Apart from this, kudos to Alex, I really love this project of his!
You should try setting ENABLE_UPDATE to true in the cloud dashboard. It will try to automatically upgrade your server to 1.16
Thanks, Alex. I already got it done, by reinstalling manually. BUT, is there a way to start a new map, without a full re-install? Maybe a terminal command, or just a parameter and then reboot? And could the server start a new map using a seed? (I need to get a map, the kids like - they gave me this as homework :-))
