Node feature discovery for Kubernetes

Overview

This software enables node feature discovery for Kubernetes. It detects hardware features available on each node in a Kubernetes cluster, and advertises those features using node labels.

Feature sources

• CPUID for x86 CPU details
• Intel Resource Director Technology
• Intel P-State driver

Feature labels

The published node labels encode a few pieces of information:

• A "namespace" to denote the vendor/provider (e.g. node.alpha.intel.com).
• The version of this discovery code that wrote the label, according to git describe --tags --dirty --always.
• The source for each label (e.g. cpuid).
• The name of the discovered feature as it appears in the underlying source, (e.g. AESNI from cpuid).

Note: only features that are available on a given node are labeled, so the only label value published for features is the string "true".
