The Kubernetes scheduler is the brain of the cluster, deciding which node runs each Pod. This post is part of a series where I explore advanced scheduling mechanisms in Kubernetes. In this part, I focus on the current state of the default scheduler.

I explain how Pods move through different queues, how the scheduler picks viable nodes, and how it scores and selects the best one.
