Why Kubernetes doesn't rebalance pods in nodes? Learnk8s runs a 4-day Advanced Kubernetes course in 3 weeks, and you will get to the bottom of questions like this (spoiler: the scheduler allocates pods when they are created, and it doesn't re-evaluate decisions). You will also learn the nitty-gritty details of the Kubernetes architecture: - How pods can serve traffic even if the control plane is unavailable. - Why does Kubernetes run a single controller manager and scheduler even in HA? - Why does the kubelet prefer to poll for updates rather than the master dispatching events? This (and much more) is covered on the second day of the course. You can find the full agenda, a breakdown of the modules and how to sign up here: https://kube.events/t/5cd14a5b-bd2a-496d-9009-5cc802b45fd4 Are you training your team?
