Released on the same day as Kubernetes, cadvisor is a container monitoring daemon that collects metrics and serves them to monitoring tools. It’s built into the Kubelet, and underpins many components in Kubernetes, such as eviction and autoscaling. David Ashpole of Google Cloud is TL of Kubernetes SIG Instrumentation, and the maintainer of cadvisor; he joins Adam and Craig this week to explain where instrumentation fits in the stack, and what you should do as a Kubernetes maintainer vs. a cluster administrator. Do you have something cool to share? Some questions?
