Kubernetes Metrics Server FIPS Overview

Secure your stack with a hardened, FIPS-validated Kubernetes Metrics Server 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.

Kubernetes Metrics Server is used for Kubernetes built-in autoscaling pipelines. Use this image when you need to meet the requirements for FIPS-validated cryptographic protection.

FIPS 140-3 Certification

This image is FIPS-validated to ensure its cryptographic operations meet the Federal Information Processing Standards (FIPS) required for secure government and regulated environments. Its core cryptographic modules are validated under the NIST Cryptographic Module Validation Program (CMVP) and comply with the FIPS 140-3 standard.

To verify that the FIPS 140-3 provider is configured and active, follow the instructions in the FIPS compliance tab.

Try It Out

Take the Minimus Kubernetes Metrics Server image for a test run by looking up its version information:

docker run reg.mini.dev/metrics-server-fips --version

Ready to deploy using a Helm chart?

Prerequisites

A running Kubernetes cluster (v1.21 or higher is recommended)
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: Add Repository to your Local Client

Add the official Helm chart repository to your local Helm client.

helm repo add metrics-server https://kubernetes-sigs.github.io/metrics-server/
helm repo update

Step 3: Deploy the Chart

Deploy the Helm chart to the default namespace so it can access all the Pods in the cluster:

helm install metrics-server metrics-server/metrics-server \
  --set=image.repository=reg.mini.dev/metrics-server-fips \
  --set=image.tag=latest \
  --set=args={--kubelet-insecure-tls}

For the purpose of this test, we configured the metrics-server to skip TLS verification for the kubelet. In production, configure proper certificates with IP SANs (Subject Alternative Names) instead. We also passed the Minimus token inline to simplify the process. Standard practice is to create a Kubernetes secret. Learn more

Step 4: Monitor Pod Status

Run the following and wait for the pods to show that their status is running.

kubectl get pods -A

Technical Considerations

The Kubernetes Metrics Server FIPS image provided by Minimus is a FIPS validated, slim, security-hardened alternative to the public image. The images are largely interchangeable, with a few differences as noted below.

Kubernetes Metrics Server FIPS built by Minimus:

Runs as non-root by default as user 1000. The public image runs as user 65534.
The entrypoint is metrics-server --cert-dir=/tmp. The public version uses metrics-server.
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.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
