Chainguard Container for cis-operator

Enables running CIS benchmark security scans on a Kubernetes cluster and generates compliance reports that can be downloaded

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/cis-operator:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

Chaingaurd's cis-operator container image is comparable to the cis-operator image. Like most other Chainguard container images, the cis-operator container image contains only the dependencies it needs to function, and doesn't include things like a shell or package manager.

Getting Started

The Chainguard's cis-operator container image can be installed via the cis-operator helm chart.

Create a values.yaml file with the following values

image:
  cisoperator:
    repository: cgr.dev/ORGANIZATION/cis-operator
    tag: latest

Make sure to replace ORGANIZATION with your organization.

Run the following command to install the helm chart:

helm repo add rancher-cis-benchmark https://github.com/rancher/cis-operator
helm install https://github.com/rancher/cis-operator chart/ -n cis-operator-system -f values.yaml

We can then try creating a ClusterScan resource like below which is going to run a ClusterScan on your cluster:

apiVersion: cis.cattle.io/v1
kind: ClusterScan
metadata:
  name: k3s-e2e-scan
  namespace: cis-operator-system
spec:
  scanProfileName: k3s-cis-1.9-profile
  scoreWarning: pass

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
