About this Mod

ClusterComputers is a Minecraft mod for running Kubernetes-powered computers in
Minecraft.

ClusterComputers works similarly to other computer mods like ComputerCraft and
OpenComputers. However, other computer mods tend to provide limited environments
that only allow running Lua scripts. The goal of ClusterComputers is to provide
a fully-customizable environment that allows for running any type of code that
you want.

It accomplishes this by running a pod in Kubernetes for each computer that you
create in Minecraft. The pod contains a regular container that provides full
access to the Linux command line and allows you to use any programming language
that you wish. You can also run regular command-line programs within the
container, such as vim or emacs.

The default container image comes with a Python library that allows you to
control computers using Python, but you can also use other languages, or use a
different container image altogether.

Although running a pod for each computer provides a lot of customizability, it
does come with downsides. Before you can use this mod, you need to set up a
Kubernetes cluster, which requires technical knowledge. The pods are also
relatively expensive to run compared to an embedded Lua environment.

⚠️ This mod requires external setup. Before you can use it, you need to set up a
Kubernetes cluster and deploy the required ClusterComputers components to it.

Frequently Asked Questions

ClusterComputers server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is ClusterComputers compatible with fabric and forge?

ClusterComputers officially supports fabric, forge for Minecraft 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with ClusterComputers – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if ClusterComputers consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
