Overview

OS-Shell Cassandra IAMGuarded is a specialized image providing shell and Cassandra-specific utilities, used exclusively by the Cassandra Helm chart for dynamic seed discovery operations. This image includes additional dependencies beyond the standard os-shell-iamguarded image that are required for Cassandra's dynamic seed discovery feature.

Important: This image should only be used with the Cassandra Helm chart and is not intended as a general-purpose shell image.

Helm Chart Installation

This image is specifically designed for the Cassandra Helm chart and is used for dynamic seed discovery operations. It does not come with its own Helm Chart.

It is not needed to specify the image when using Helm Charts with Chainguard's registry.

Setting the image registry, repository and tag / digest may be needed when using mirroring strategies.

Example values.yaml for the Cassandra Helm chart that enables dynamic seed discovery and pins the image to specific digest:

# OS Shell Cassandra image for dynamic seed discovery
dynamicSeedDiscovery:
  enabled: true
  image:
    registry: myregistry.example.com
    repository: mirrored/os-shell-cassandra-iamguarded
    digest: sha256:... # Use specific digest instead of tag

How to Use Chainguard Helm Charts

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system 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 development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
