For those with access, this container image is available on cgr.dev:

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 images are compatible with the upstream CloudNativePG barman-cloud plugin. This plugin provides PostgreSQL backup and recovery capabilities to S3-compatible storage using Barman Cloud tools.

The plugin consists of two components:

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

Getting Started

Using Chainguard's CloudNative-PG Operator Images

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

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

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

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

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

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

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