How to set limits on own resources in node in kubernetes?

Question

Kubernetes

Good afternoon everyone!
In kubernetes, you can set limits on the use of system resources for a node: memory, processor, etc.
Is it possible to create some kind of own type of resource that k8s will monitor and will not create new pods on this node if this resource is not enough? And how to implement it?

Answer 1

Yes, there are such ways. But which one is suitable depends on the resource. The simplest option would be through extended resources .
In a more complex case, you will have to create a kubernetes resource, probably its controller.
