Chainguard Container for cass-operator-fips

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/cass-operator-fips:latest

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

Compatibility Notes

The Chainguard cass-operator-fips container image is a FIPS-enabled variant of the upstream k8ssandra/cass-operator image. As with other Chainguard Containers, the cass-operator-fips image was designed with minimalism in mind, and therefore doesn't contain things like a shell or package manager.

Getting Started

The cass-operator-fips image can be used as a drop-in replacement for the standard cass-operator in Kubernetes deployments. The operator manages Apache Cassandra clusters on Kubernetes, automating tasks like deployment, scaling, and configuration management.

Prerequisites

Before deploying the operator, ensure you have:

• A Kubernetes cluster (v1.21+)
• Helm 3.x installed
• kubectl configured to access your cluster

Deploying the Operator

First, add the required Helm repositories:

helm repo add jetstack https://charts.jetstack.io
helm repo add k8ssandra https://helm.k8ssandra.io/stable
helm repo update

The cass-operator requires cert-manager for certificate management. Install it first:

helm install cert-manager jetstack/cert-manager \
  --namespace cass-operator \
  --create-namespace \
  --set installCRDs=true \
  --wait

Now deploy the cass-operator using the FIPS-compliant image:

helm install cass-operator k8ssandra/cass-operator \
  -n cass-operator \
  --set image.registry="" \
  --set image.repository="cgr.dev/ORGANIZATION/cass-operator-fips" \
  --set image.tag="latest" \
  --wait

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

Verify the Deployment

Check that the operator is running:

kubectl get pods -n cass-operator

You should see the cass-operator pod in a Running state:

NAME                             READY   STATUS    RESTARTS   AGE
cass-operator-xxxxxxxxx-xxxxx    1/1     Running   0          1m

The operator is now ready to manage Cassandra clusters. You can create CassandraDatacenter custom resources to deploy Cassandra clusters managed by the operator.

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.
