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

Compatibility Notes

The Chainguard plugin-barman-cloud-fips images are FIPS-hardened versions of the CloudNativePG barman-cloud plugin. This plugin provides PostgreSQL backup and recovery capabilities to S3-compatible storage using Barman Cloud tools with FIPS 140-2 compliant cryptographic operations.

FIPS 140-2 Compliance

The plugin-barman-cloud-fips Chainguard Image ships with a validated redistribution of the OpenSSL's FIPS provider module, ensuring all cryptographic operations used for backup encryption and S3 communication meet FIPS 140-2 standards. This includes:

• Backup encryption - All backup data is encrypted using FIPS-approved algorithms
• S3 communication - HTTPS connections to S3-compatible storage use FIPS-validated TLS
• Authentication - AWS credentials and authentication mechanisms comply with FIPS standards

For comprehensive information on FIPS support in Chainguard Images:

• FIPS-enabled Chainguard Images Guide
• FIPS 140-2 Standard Overview

The plugin consists of two components:

• Plugin Manager (plugin-barman-cloud-fips): Runs as a deployment and manages plugin lifecycle
• Sidecar (plugin-barman-cloud-sidecar-fips): Injected into PostgreSQL pods to handle backup operations

Getting Started

Using Chainguard's FIPS-Compliant CloudNative-PG Operator

Create a values-fips.yaml file to configure the CloudNative-PG operator with Chainguard FIPS images:

# values-fips.yaml for CloudNative-PG with Chainguard FIPS images
image:
  repository: cgr.dev/ORGANIZATION/cloudnative-pg-fips
  tag: latest
  pullPolicy: IfNotPresent

helm repo add cnpg https://cloudnative-pg.github.io/charts
helm repo update

# Install with Chainguard FIPS images
helm install cnpg cnpg/cloudnative-pg \
  --namespace cnpg-system \
  --create-namespace \
  --values values-fips.yaml

# Wait for operator to be ready
kubectl wait --for=condition=Available deployment/cnpg-cloudnative-pg -n cnpg-system --timeout=120s

# Verify the FIPS image is being used
kubectl get deployment cnpg-cloudnative-pg -n cnpg-system \
  -o jsonpath='{.spec.template.spec.containers[0].image}'

Download the plugin manifest and modify it to use Chainguard FIPS images:

# Set your custom FIPS images
PLUGIN_IMAGE="cgr.dev/ORGANIZATION/plugin-barman-cloud-fips:latest"
SIDECAR_IMAGE="cgr.dev/ORGANIZATION/plugin-barman-cloud-sidecar-fips:latest"

# Download and modify the manifest with yq to inject custom sidecar image
curl -fsSL "https://github.com/cloudnative-pg/plugin-barman-cloud/releases/download/v0.6.0/manifest.yaml" | \
  yq eval "select(.kind == \"Secret\") |= .data.SIDECAR_IMAGE = \"$(echo -n ${SIDECAR_IMAGE} | base64)\"" | \
  kubectl apply -f -

# Update the plugin operator deployment with custom FIPS image
kubectl set image deployment/barman-cloud "*=${PLUGIN_IMAGE}" -n cnpg-system
kubectl rollout status deployment barman-cloud -n cnpg-system --timeout=120s

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.
