[opensuse-buildservice] Thoughts on deploy Open Build Service in kubernetes cluster
Hey guys, Recently, we start to evaluate Open Build Service for our package build and publish system, considering the portability, scalability and ecosystem, our most of other services are deployed on kubernetes cluster, therefore, we are just wondering whether it's a possible or a good choice to deploy OBS in kubernetes. We would like start this thread for the purpose of discussion on these below: 1. Does there anyone have tried to deploy OBS in k8s cluster, Is there any suggestion/warning on that direction? 2. If possible, what's the best practice on how to deploying OBS, and what's the scale we can get? 3. If not, what's the disadvantages or issues we would have within that deployment? Thanks for your sharing! TommyLike -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

running an instance is easy. Getting it integrated, solving the KVM nesting
overhead (about 50% slowdown, but you may ignore it, if acceptable) and
integrating into the dispatch queue is a complete different topic.

KVM nesting overhead? what KVM nesting? Kubernetes is docker containers, not virtual machines...

Could you please provide more detail on the `integrating into the dispatch queue is a complete different topic.` does this mean that due to the kubernetes cluster network model, the dispatch logic would incompatible?

Based on my understanding, there could be two possibilities. 1. When the kubernetes cluster especially the work nodes are deployed on KVM based instances, especially on public cloud. 2. When the container runtime is based on VM solution, for instance Kata container gvisor or firecracker. sometimes it's a requirement due to the security reason. 3. Or both. -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

you still need a kvm inside for security reasons and to guarantee the right
kernel.

But running vms inside of containers is not nesting kvm - it only gets nested if kubernetes is running in vms, which is not necessarly the case.

kubernetes nodes is usually not setup on plain hardware, but running already
in some kvm. At least in the scenarios I had contact with.
