Some variables require a server reinstall to take effect. Read the variable description carefully.
Startup Command
The startup command shows exactly what runs when your server starts:
java -Xms128M -Xmx{{SERVER_MEMORY}}M -jar {{SERVER_JAR}}
{{BRACKETS}} are replaced with actual values.
Docker Image
Your server runs in a Docker container with a specific image:
| Game | Typical Image |
|---|
| Minecraft (Java) | Java 17 |
| Minecraft (Older) | Java 8 |
| Vintage Story | Custom VS image |
The Docker image determines available Java versions and system dependencies. Contact support if you need a different image.

For Minecraft, different versions require different Java:
| Minecraft Version | Java Required |
|---|
| 1.20.5+ | Java 21 |
| 1.17 - 1.20.4 | Java 17 |
