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/external-dns-bitnami-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

External-dns is an open-source tool that allows configuring external DNS servers (AWS Route53, Google CloudDNS and others) for Kubernetes Ingresses and Services.

This Chainguard image provides compatibility with the Bitnami external-dns helm chart.

FIPS Support

The external-dns-bitnami-fips Chainguard Image ships with a validated redistribution of the OpenSSL's FIPS provider module. For more on FIPS support in Chainguard Images, consult the guide on FIPS-enabled Chainguard Images on Chainguard Academy

Deploying with Helm

The external-dns (Bitnami) image can be deployed using the helm charts. Such as:

helm install external-dns oci://registry-1.docker.io/bitnamicharts/external-dns --values values.yaml

Where values.yaml file should point to the Chainguard images as well as configuration for external-dns. Such as:

# use Chainguard external-dns-bitnami-fips image
image:
  registry: cgr.dev
  repository: ORGANIZATION/external-dns-bitnami-fips
  tag: latest

# configure provider configuration
provider: # provider name
# provider specific configuration follows

On December 10, 2024, Bitnami updated their Helm charts to reject non-Bitnami images by default. To disable this behavior and use Chainguard images, you must specify the following parameter:

global.security.allowInsecureImages: true

For more information, please refer to the change notification from Bitnami.

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.
