You might have come across the open source tools like node problem detector and descheduler, you may wonder how these tools would be useful to the real time container ecosystem.

This talk will help you to gain more details on how you can leverage in your container footprint.

Node Problem Detector (NPD) is deployed as a daemon set which runs on worker and Infra nodes. It is designed to inspect various subsystems and components of the node and report any problems or anomalies it detects to apiserver. It aims to make various node problems visible to the upstream layers in the cluster management stack, this information helps Cluster Administrators proactively identify and address issues that could impact the node’s health and stability.

A descheduler is a specialized component in Kubernetes that helps to improve cluster resource utilization and balance by evicting (and subsequently scheduling elsewhere) Pods from nodes that meet certain criteria. This also runs as a daemon set
