⎈ PID 1 process cannot be killed, zombie processes, Understanding DNS, Kubernetes self-healing in practice, topology-aware routing

There are no "right" requests or limits in Kubernetes because, as soon as you set one, it's already wrong 😅

So, how do you set requests and limits? How do you size Kubernetes nodes for workloads with constantly changing CPU and memory profiles?

I will try to answer those hard questions tomorrow in this webinar.

Join me!
