k0s hardware requirements at a glance
k0s is a CNCF-certified lightweight, Kubernetes distribution with zero dependencies and zero opinion. This is an orchestration or infrastructure platform. Plan control-plane quorum/state, networking, worker/guest resources and failure domains separately; a single-node lab is not a complete production cluster.
- RAM
- The upstream README describes a modest 1 GB RAM system requirement for k0s. This component baseline does not include the operating system or scheduled application workloads.
- CPU
- The README lists 1 vCPU for k0s itself. Worker applications and high-availability control roles require additional capacity.
- Storage
- Include cluster state, container images, logs, persistent volumes and independent backups.
- Required services
- Follow the supported upstream runtime and complete k0s deployment topology for the selected release. This is an orchestration or infrastructure platform. Plan control-plane quorum/state, networking, worker/guest resources and failure domains separately; a single-node lab is not a complete production cluster.
- Main sizing variable
- managed objects/nodes, reconciliation frequency, scheduled jobs, API activity and worker concurrency
- Practical Zima starting point
- Conditional lab, data-storage or supporting-service hardware only; a complete production deployment requires a separately verified host meeting the upstream requirements. This is an orchestration or infrastructure platform. Plan control-plane quorum/state, networking, worker/guest resources and failure domains separately; a single-node lab is not a complete production cluster.
From official requirements to the right setup
Plan the complete k0s workload before selecting a server.
-
Official requirements
Choose the exact edition, stable release and supported container/runtime. Follow the supported upstream runtime and complete k0s deployment topology for the selected release. This is an orchestration or infrastructure platform. Plan control-plane quorum/state, networking, worker/guest resources and failure domains separately; a single-node lab is not a complete production cluster.
-
Confirm your needs
Test a representative busy operation: managed objects/nodes, reconciliation frequency, scheduled jobs, API activity and worker concurrency Record peak resident memory, CPU, disk latency and completion time, including other containers.
-
Leave room to grow
Place active state on reliable persistent storage. Persist declarative configuration, credentials, controller state, workflow history and recoverable management state. Budget working space for an upgrade or import and test recovery before relying on the deployment.

Run it on ZimaOS
Follow the supported upstream runtime, operating system and complete service topology for the selected release. On ZimaOS, consider Custom Install only when a maintained compatible amd64 image and every required host capability have been verified. Otherwise use a separately supported Linux environment; this guide does not certify an unverified container deployment. This is an orchestration or infrastructure platform. Plan control-plane quorum/state, networking, worker/guest resources and failure domains separately; a single-node lab is not a complete production cluster.

When to upgrade your hardware
Use observed k0s workload pressure to decide when an upgrade is warranted.
Busy operations exceed the available window
The complete stack runs short of memory
Persistent data approaches available capacity
Inspect the application and each required service for OOM events, sustained swap or growing queues. Reduce unnecessary concurrency before adding capacity.
Shared hosts and background work.Persist declarative configuration, credentials, controller state, workflow history and recoverable management state. Track primary state and backup retention separately.
Long-lived installations and growing collections.Plan hardware growth with confidence
Address storage, memory, compute and deployment limits separately.
Use suitable active storage
Put latency-sensitive application/database state on durable local SSD storage and keep recoverable copies.
SATA or PCIe SSD according to measured data growth.Add memory for the complete stack
Choose a higher-RAM host when peak application and companion-service usage leaves inadequate OS headroom.
ZimaBoard 2 832 or ZimaBoard 2 1664 according to the measured constraint.Separate capacity from compute
A multi-drive system helps when retained content and backup storage are the problem; it is not automatically a faster application.

Zima Blade Little yet Powerful
Maybe I am not digital natives but I live with PCs since 12 years old in 1984 when IBM PC clone come to my home. Many years have passed and many operating system I've tried. For me Zima blade and CasaOS was a quantum leap for home PC enthusiast and server lab machine to make me stay curious and relevant for this era.
★★★★★
Very good!!
I use ZimaCube Pro as 5th Proxmox cluster node. It runs several VMs and containers, including a VM with GPU passthrough to run a self-hosted LLM. A specific LXC container runs a Samba server for NAS capabilities using four of six RAID 6 SATA HDDs with ZFS.
★★★★★
Great innovation for mini server!
It is very useful and makes a powerful mini server for many purposes, including university and college students in engineering and electronics. Thank you so much for making this server.

Avaliação ZimaBoard 2
Construí um servidor de uso pessoal. O desempenho está muito bom e funciona perfeitamente onde quer que eu esteja. A surpresa é não dependermos de grandes estruturas para termos nosso próprio servidor de dados. Como iniciante, estou gostando bastante do ZimaOS, pois ele é simples e eficiente.
Frequently asked questions
Answers to k0s RAM, CPU, storage, Docker, database and ZimaOS sizing questions.
How much RAM should I plan for k0s?
The upstream README describes a modest 1 GB RAM system requirement for k0s. This component baseline does not include the operating system or scheduled application workloads. Include ZimaOS, the application and its companion services rather than reserving the entire machine for one container.
What drives the CPU requirement?
The README lists 1 vCPU for k0s itself. Worker applications and high-availability control roles require additional capacity. The workload to test is: managed objects/nodes, reconciliation frequency, scheduled jobs, API activity and worker concurrency
Which data must survive a container update?
Persist declarative configuration, credentials, controller state, workflow history and recoverable management state. Preserve a consistent database/file set and verify that your recovery procedure restores a working application.
What other services belong in the budget?
Follow the supported upstream runtime and complete k0s deployment topology for the selected release. This is an orchestration or infrastructure platform. Plan control-plane quorum/state, networking, worker/guest resources and failure domains separately; a single-node lab is not a complete production cluster.
