Chainguard Container for cass-operator

cass-operator, is a Kubernetes operator for managing Apache Cassandra. It automates tasks like deployment, scaling, and configuration management, facilitating the integration of Cassandra clusters with Kubernetes environments.

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:latest

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

Usage

cass-operator is a Kubernetes operator, which can be deployed using helm. Refer to the upstream repositories documentation for how to get started with cass-operator.

To use our minimal, wolfi-based image with this Helm chart you'll need to override the image used by the official helm chart and specify the chainguard image as per below example:

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

helm install cass-operator k8ssandra/cass-operator -n cass-operator
helm upgrade cass-operator \
    -n cass-operator \
    --set image.repository=cgr.dev/chainguard/cass-operator \
    --set image.tag=latest
    --wait \
    k8ssandra/cass-operator
}

As per project documentation, by default, the Helm installation requires cert-manager to be present in the Kubernetes installation. If you do not have cert-manager installed, follow the steps at cert-manager's documentation.

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.
