Use NPD to Detect Node Problems in Kubernetes Clusters

This lab uses Alibaba Cloud Container Service. This lab describes how to use the node problem detector (NPD) service to detect node problems in Kubernetes clusters. NPD aims to make various node problems visible to the upstream layers in cluster management stack. It is a daemon which runs on each node, detects node problems, and reports them to APIServer. NPD can either run as a DaemonSet or run standalone.
