Chainguard Container for litmus-chaos-operator-fips

LitmusChaos Operator is a Kubernetes operator that manages the lifecycle of chaos experiments. It watches for ChaosEngine custom resources and orchestrates chaos injection into target applications for resilience testing. This is the FIPS-validated variant.

Chainguard Containers are regularly-updated, secure-by-default container images.

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

Overview

The LitmusChaos Operator is a Kubernetes operator that manages the lifecycle of chaos experiments. It watches for ChaosEngine custom resources and orchestrates chaos injection into target applications, enabling resilience testing in Kubernetes environments.

This is the FIPS-validated variant of the litmus-chaos-operator image, built with FIPS-hardened OpenSSL.

This image is a drop-in replacement for the upstream litmuschaos/chaos-operator image.

Compatibility

This image can be used as a replacement for the litmuschaos/chaos-operator image in any LitmusChaos deployment. It is compatible with the official Litmus Helm chart.

Usage

Helm Installation

LitmusChaos requires two Helm deployments: the ChaosCenter platform (frontend, server, MongoDB) and the chaos-operator itself.

1. Deploy the ChaosCenter Platform

First, deploy the LitmusChaos platform and configure it to use the Chainguard FIPS chaos-operator image via portal.server.graphqlServer.imageEnv:

helm repo add litmuschaos https://litmuschaos.github.io/litmus-helm/

helm install litmus litmuschaos/litmus \
  --namespace=litmus --create-namespace \
  --set portal.frontend.service.type=NodePort \
  --set portal.server.graphqlServer.imageEnv.LITMUS_CHAOS_OPERATOR_IMAGE=cgr.dev/ORGANIZATION/litmus-chaos-operator-fips:latest

2. Deploy the Chaos Operator

Then deploy the chaos-operator subchart directly, overriding the image to use the Chainguard FIPS variant:

# Clone the litmus-helm repo for the subchart
git clone https://github.com/litmuschaos/litmus-helm.git

helm install chaos-operator litmus-helm/charts/litmus-agent/charts/chaos-operator \
  --namespace=litmus \
  --set image.repository=cgr.dev/ORGANIZATION/litmus-chaos-operator-fips \
  --set image.tag=latest

3. Install CRDs

The chaos-operator subchart does not bundle CRDs. Install them from the upstream repository:

kubectl apply -f https://raw.githubusercontent.com/litmuschaos/chaos-operator/VERSION/deploy/chaos_crds.yaml

Replace VERSION with the version that matches your operator (e.g., 3.26.0).

Verify the CRDs are established:

kubectl wait --for=condition=Established crd/chaosengines.litmuschaos.io --timeout=30s
kubectl wait --for=condition=Established crd/chaosexperiments.litmuschaos.io --timeout=30s
kubectl wait --for=condition=Established crd/chaosresults.litmuschaos.io --timeout=30s

Running a Chaos Experiment

Once the operator is running and CRDs are installed, you can run chaos experiments by creating ChaosExperiment and ChaosEngine custom resources. See the non-FIPS litmus-chaos-operator README for detailed examples of creating ChaosExperiment and ChaosEngine resources.

Docker

docker pull cgr.dev/ORGANIZATION/litmus-chaos-operator-fips:latest
docker run --rm cgr.dev/ORGANIZATION/litmus-chaos-operator-fips:latest --help

FIPS Support

This image is built with FIPS-hardened OpenSSL (openssl-config-fipshardened), ensuring that all cryptographic operations comply with FIPS 140-2/140-3 standards. This variant is suitable for environments that require FIPS-validated cryptography, such as U.S. federal government workloads and regulated industries.

The FIPS variant is functionally identical to the standard litmus-chaos-operator image, with the only difference being the use of FIPS-compliant cryptographic libraries.

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.
