Cluster-Proportional-Autoscaler-FIPS Overview

Secure your stack with a FIPS-validated, hardened Cluster-Proportional-Autoscaler-FIPS 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.

Cluster-Proportional-Autoscaler is a Kubernetes controller that resizes the replica count of a target Deployment, ReplicaSet, or ReplicationController in proportion to the size of the cluster. It polls the number of schedulable nodes and CPU cores, then applies a linear formula or step-function ("ladder") mapping defined in a ConfigMap to calculate the target replica count, keeping cluster-wide add-ons like CoreDNS appropriately sized as the cluster grows or shrinks. 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

Prerequisites

A running Kubernetes cluster
Helm (Installation instructions)
kubectl installed and configured

Step 1: Add Repository to your Local Client

Add the Helm chart to your local Helm client.

helm repo add cluster-proportional-autoscaler https://kubernetes-sigs.github.io/cluster-proportional-autoscaler
helm repo update

Step 2: Create a Local YAML File to Override Chart Defaults

Save the following to a values.yaml file in your project directory. This example scales the coredns Deployment in the kube-system namespace using linear mode:

image:
  repository: "reg.mini.dev/cluster-proportional-autoscaler-fips"
  tag: "latest"
options:
  target: "deployment/coredns"
  namespace: "kube-system"
config:
  linear:
    coresPerReplica: 2
    nodesPerReplica: 1
    min: 1
    max: 10

Step 3: Deploy the Chart

helm upgrade --install cluster-proportional-autoscaler cluster-proportional-autoscaler/cluster-proportional-autoscaler \
  -f values.yaml \
  -n kube-system

Wait a minute and check that the Pod is up and running:

kubectl -n kube-system get po -l app.kubernetes.io/name=cluster-proportional-autoscaler

Confirm that Minimus images were deployed:

kubectl -n kube-system describe pods -l app.kubernetes.io/name=cluster-proportional-autoscaler | grep Image:

Clean Up

Uninstall the chart to delete the ConfigMap, Deployment, and other resources it created:

helm uninstall cluster-proportional-autoscaler -n kube-system

Technical Considerations

The Cluster-Proportional-Autoscaler-FIPS image provided by Minimus is a FIPS-validated, slim, security-hardened alternative to the public image from registry.k8s.io. The images are largely interchangeable, with a few differences as noted below.

Cluster-Proportional-Autoscaler-FIPS built by Minimus:

Runs as a non-root user by default, matching the public image's non-root default of user 65535.
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.
