Node-Feature-Discovery Overview

Secure your stack with a hardened Node-Feature-Discovery image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Node Feature Discovery lets Kubernetes schedule workloads based on the actual hardware and system capabilities of each node — CPU instruction sets, GPUs, kernel version, and more — instead of requiring platform teams to manually inventory nodes and apply labels by hand. It runs continuously as a cluster add-on, keeping those labels current as nodes are added, removed, or reconfigured.

Try It Out

Prerequisites

A running Kubernetes cluster
Helm v3.8 or higher for OCI support (Installation instructions)
kubectl installed and configured

Step 1: Start Cluster

If you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. Deployment instructions

Step 2: Deploy via Helm Chart

Update the chart version as appropriate and deploy:

helm install nfd oci://registry.k8s.io/nfd/charts/node-feature-discovery \
  --version 0.18.3 \
  --namespace node-feature-discovery \
  --create-namespace \
  --set image.repository=reg.mini.dev/node-feature-discovery \
  --set image.tag=latest

Wait a minute and check that the Pods are up and running:

kubectl -n node-feature-discovery get pods

Confirm that Minimus images were deployed:

kubectl -n node-feature-discovery describe pods | grep Image:

Step 3: Confirm Node Labels

Node Feature Discovery labels each node in the cluster with the hardware and system features it detects. Confirm the labels were applied:

kubectl get no -o json | jq ".items[].metadata.labels"

"feature.node.kubernetes.io/cpu-cpuid.ADX": "true",
"feature.node.kubernetes.io/cpu-cpuid.AESNI": "true",
"feature.node.kubernetes.io/kernel-version.major": "6",

Step 4: Clean Up

Uninstall the chart to delete the namespace and its resources, including Pods, Deployments, Services, Secrets, ConfigMaps, etc.:

helm uninstall nfd -n node-feature-discovery

Technical Considerations

The Node-Feature-Discovery image provided by Minimus is a slim, security-hardened alternative to the public image. The images are largely interchangeable, with a few differences as noted below.

Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.
