Supported Platforms¶

This page summarizes the supported runtime targets for Productive K3S and the practical sizing guidance for a single-node host.

The tool is prepared for production-oriented environments based on the most widely used non-proprietary operating systems across common cloud and VM platforms. In practice, that is why the supported runtime targets end up being Linux distributions.

At the same time, the development workflow provides a practical way for contributors using Windows or macOS to work on improvements to the tool scripts by using Multipass and supported Linux VMs.

Supported Targets¶

The repository is validated and supported on:

Ubuntu 24.04 LTS
Ubuntu 22.04 LTS
Debian 13 trixie
Debian 12 bookworm

Support means the retained validation evidence includes these flows:

smoke
core
full
full-rollback
full-clean

Validation Model¶

Ubuntu 24.04 has both direct hosted validation and VM-based validation
Ubuntu 22.04, Debian 12, and Debian 13 are validated through the VM harness
Debian support refers to the runtime inside the validated VM guest, not to GitHub-hosted direct-run CI

Platform Assumptions¶

package installation assumes apt-get
service management assumes systemd
VM-based integration testing is centered on multipass
Windows and macOS are relevant only as host environments capable of running Linux VMs

Minimum Hardware¶

Practical minimum for the full stack:

CPU: 4 vCPU
RAM: 12 GB
Disk: 60 GB free SSD space

Recommended for a smoother experience:

CPU: 6-8 vCPU
RAM: 16 GB
Disk: 100 GB+ free SSD space

Why the baseline is not smaller¶

Rancher and Longhorn add steady control-plane overhead
the internal registry consumes persistent storage
stateful workloads need headroom beyond the base platform itself
low free disk space is especially problematic for Longhorn
