Chainguard Container for contour-bitnami-fips

Contour is an ingress controller for Kubernetes that works by deploying the Envoy proxy as a reverse proxy and load balancer. Contour supports dynamic configuration updates out of the box while maintaining a lightweight profile.

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/contour-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

Chainguard's contour-bitnami-fips container is a Bitnami-compatible image and is similar to the official bitnami/contour image on Docker Hub, with a comparable user (1001) and a shell included.

Beyond this, it contains only the essential tools and dependencies needed to function, excluding tools like a package manager.

FIPS support

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

Getting Started

This Chainguard image is designed to be compatible with the Bitnami Helm chart, referenced in the Contour getting started documentation.

First, add the Helm repository:

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update

Create a values.yaml, specifying the Chainguard image:

# Save as values.yaml
contour:
  image:
    registry: "cgr.dev"
    repository: "chainguard/contour-bitnami-fips"
    tag: "latest"
global:
  security:
    allowInsecureImages: true

Deploy using Helm:

helm install contour bitnami/contour -f values.yaml

Following successful deployment, you will see Contour and Envoy running in the cluster:

% kubectl get po
NAME                              READY   STATUS    RESTARTS   AGE
contour-contour-c66d5cb67-z7ql6   1/1     Running   0          98s
contour-envoy-cw6vs               2/2     Running   0          98s

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.
