Contribute to leonanu/kubernetes-cluster-hard-way development by creating an account on GitHub. The Kubernetes Horizontal Pod Autoscaler can scale pods based on the usage of resources, such as CPU and memory.This is useful in many scenarios, but there are other use cases where more advanced metrics are needed - like the waiting connections in a web server or the latency in an API. Kubernetes has solved many challenges, like speed, scalability, and resilience, but it's also introduced a new set of difficulties when it comes to monitoring infrastructure. Modified 1 year, 1 month ago. Ask Question Asked 1 year, 11 months ago. This step might fail if the node is offline or unresponsive. A node doesn't seem to be scheduling new pods. .
