Chainguard Container for flagger-fips

Flagger automates canary deployments and A/B testing for Kubernetes applications.

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/flagger-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 flagger image is comparable to the upstream flagger image

FIPS Support

This Chainguard Container ships with a validated redistribution of OpenSSL's FIPS provider module. For more on FIPS support in Chainguard Containers, consult the guide on FIPS-enabled Chainguard Containers on Chainguard Academy.

Getting Started

Flagger is a progressive delivery tool that automates the release process for applications running on Kubernetes. It reduces the risk of introducing a new software version in production by gradually shifting traffic to the new version while measuring metrics and running conformance tests.

Verify the Image

You can verify the image works by running:

docker run --rm cgr.dev/$ORGANIZATION/flagger-fips:latest --help
docker run --rm cgr.dev/$ORGANIZATION/flagger-fips:latest -version

Deploying with Helm

Flagger is typically deployed using the upstream Flagger Helm chart.

helm repo add flagger https://flagger.app

helm install flagger flagger/flagger \
  --namespace flagger-system \
  --create-namespace \
  --set image.repository=cgr.dev/$ORGANIZATION/flagger-fips \
  --set image.tag=latest \
  --set meshProvider=kubernetes

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

Verifying the Installation

Once deployed, you can verify Flagger is running correctly:

kubectl rollout status deployment/flagger -n flagger-system

Verify that the Flagger CRDs are installed:

kubectl get crd canaries.flagger.app
kubectl get crd metrictemplates.flagger.app
kubectl get crd alertproviders.flagger.app

Documentation and Resources

Please refer to the upstream documentation for full instructions on how to use and configure Flagger for progressive delivery.

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.
