kubespray VS kairos

When it came to deployment, I had several options, and I chose the hard way: deploying Kubernetes on bare metal nodes using KubeSpray. Troubleshooting bare metal Kubernetes deployments honed my skills in pinpointing issues. This hands-on experience provided a deep understanding of how each component, like the Control Plane, kubelet, Container Runtime, and scheduler, interacts to orchestrate containers.

Worth noting that if you like ansible, Kubespray has had documented air-gap installation since 2018 https://github.com/kubernetes-sigs/kubespray/commit/963c3479...

calico v3.7.3 kubernetes v1.16.0 installed via kubespray https://github.com/kubernetes-sigs/kubespray

About 1yr ago I ran k8s with 300 nodes using kube spray https://github.com/kubernetes-sigs/kubespray . Never had any real issue with it. We did finally move to the cloud though.

I would highly recommend https://github.com/kubernetes-sigs/kubespray

We build our own distro called Compliant Kubernetes, and we use (a fork of) kubespray to install the base Kubernetes layer. Our distro is entirely open source, so you can use it as a reference, if you want.

If you want to run Kubernetes on VM's you can look into kubespray and play around with the options for installing and checking the configuration after the fact.

I've been eyeing Kairos [1] which is an OS lifecycle management system for k3s which looks like a nice way to deploy k3s.

kairos.io – Turn your existing distro into an immutable OS with k8s. It is the logical successor of what k3os intended (kind of).

Check out this TNS blog and Kairos blog about the Kairos project. It is a meta distribution, which addresses the issues around immutable distros at a more fundamental level while providing much more flexibility.

Kairos could fit the bill here - I don't think it supports Windows but it does have a cool Network Boot project called AuroraBoot.

kairos.io

Did you heard about https://github.com/kairos-io/kairos ? It supports any base OS (Fedora, openSUSE, Alpine, Rockylinux, Ubuntu, ..), and follows strongly the same K3OS principles. It is immutable, with an A/B upgrading mechanism and it is container based so it is easy to customize to fit your needs. It is community-driven, with no strings attached to any distribution or vendor.

Yes Kairos. KaiOS is a mobile Linux distribution unrelated to Kubernetes.

up to now we have MetalLB and Kubevirt, but here is a list of the ones that were brought up by the community (and planning to add): https://github.com/kairos-io/kairos/issues/592, feel free to add your feedback and tell what you would like to see there!
