Chainguard Container for cloudnative-pg

Minimal Wolfi-based image for CloudNative PG, a comprehensive platform designed to seamlessly manage PostgreSQL databases within Kubernetes environments.

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/cloudnative-pg:latest

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

CloudNative PG is a platform for managing PostgreSQL databases within Kubernetes environments.

These images consist of the CloudNative PG operator as well as PostgreSQL images that have been extended to support the full functionality of the CloudNative PG platform.

Deploying CloudNative PG

To deploy CloudNative PG, install the CNPG Helm chart repository:

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

Deploy the operator:

helm upgrade --install cnpg \
  --namespace cnpg-system \
  --create-namespace \
  cnpg/cloudnative-pg \
  --set image.repository="cgr.dev/<REGISTRY>/cloudnative-pg" \
  --set image.tag="latest"

And now deploy the database:

helm upgrade --install database \
  --namespace database \
  --create-namespace \
  cnpg/cluster \
  --set cluster.imageName="cgr.dev/<REGISTRY>/postgres-cloudnative-pg:<POSTGRES VERSION>"

Note, you must provide a Postgres version (I.E. 15, 16, etc) as the operator expects the versioned tag for migrations.

Alternatively, deploy the database with pooler enabled using Chainguard's PgBouncer image:

helm upgrade --install database \
  --namespace database \
  --create-namespace \
  cnpg/cluster \
  --set cluster.imageName="cgr.dev/<REGISTRY>/postgres-cloudnative-pg:<POSTGRES VERSION>"
  --set pooler.enabled=true \
  --set pooler.template.spec.containers[0].name="pgbouncer" \
  --set pooler.template.spec.containers[0].image="cgr.dev/<REGISTRY>/pgbouncer:latest"

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.
