@ -41,8 +41,11 @@ memory usage. The kubelet acts as a bridge between the Kubernetes master and
the nodes, managing the pods and containers running on a machine. The kubelet
translates each pod into its constituent containers and fetches individual
container usage statistics from the container runtime through the container
runtime interface. The kubelet fetches this information from the integrated
cAdvisor for the legacy Docker integration. It then exposes the aggregated pod
runtime interface. If you use a container runtime that uses Linux cgroups and
namespaces to implement containers, and the container runtime does not publish
usage statistics, then the kubelet can look up those statistics directly
(using code from [cAdvisor](https://github.com/google/cadvisor)).
No matter how those statistics arrive, the kubelet then exposes the aggregated pod
resource usage statistics through the metrics-server Resource Metrics API.
This API is served at `/metrics/resource/v1beta1` on the kubelet's authenticated and
read-only ports.
