Chainguard Container for cert-manager-csi-driver-fips

A Kubernetes CSI driver that automatically mounts signed certificates to Pods using ephemeral volumes

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/cert-manager-csi-driver-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

Chainguard's cert-manager-csi-driver-fips image is comparable to the quay.io/jetstack/cert-manager-csi-driver image. As with many of Chainguard's other container images, this image contains only the minimum number of dependencies it needs to function. It doesn't include things like a shell or package manager.

FIPS support

Chainguard's cert-manager-csi-driver-fips image ships with a validated redistribution of the OpenSSL FIPS provider module. For more on FIPS support in Chainguard container images, consult the guide on FIPS-enabled Chainguard Containers on Chainguard Academy.

Even though the image itself is FIPS complient, its PKCS#12 feature is not. When you set any pkcs12-* volume attribute, the driver calls the LegacyRC2 encoder in SSLMate/go-pkcs12, which encrypts certificates with RC2-40-CBC and private keys with 3DES, both wrapped with SHA-1. These ciphers are no longer permitted for encryption under FIPS-140-3, so a Go binary running in FIPS mode rejects them and the volume mount fails.

Getting Started

Pre-requisites

• A Kubernetes cluster with cert-manager installed

Deployment

Create a values.yaml file with the following content:

image:
  repository: cgr.dev/ORGANIZATION/cert-manager-csi-driver-fips
  tag: latest

To install csi-driver, use Helm:

helm repo add jetstack https://charts.jetstack.io --force-update

helm upgrade cert-manager-csi-driver-fips jetstack/cert-manager-csi-driver \
  --install \
  --namespace cert-manager \
  -f values.yaml \
  --wait

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.
