Chainguard Container for pgpool2-fips

Middleware that works between PostgreSQL servers and a PostgreSQL database client.

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/pgpool2-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

The Chainguard Steampipe Image is meant to provide the pgpool2 package in a container. It currently does not have an external counterpart image which is actively maintained. However, the image is similar to the discontinued upstream image for pgpool-II. Like most other Chainguard Images, this image has few-to-zero CVEs and does not run as the root user.

Note: Pgpool2 provides md5 password encryption support via its built-in pg_md5 utility, and does not use system OpenSSL for this purpose.

Getting Started

Pgpool-II on Kubernetes

Prerequisites: Kubernetes Cluster, kubectl, PostgreSQL Operator and a PostgreSQL Cluster

Configuration: There are two ways you can configure Pgpool-II.

• Using environment variables
• Using a ConfigMap

Pgpool-II deployment example:

# Download the Pgpool-II deployment manifest
curl -O https://raw.githubusercontent.com/pgpool/pgpool2_on_k8s/master/pgpool-deploy-metrics.yaml

# Update the deployment to use Chainguard's pgpool2-fips image
sed -i 's|image: pgpool/pgpool2$|image: cgr.dev/ORGANIZATION/pgpool2-fips:latest|' pgpool-deploy-metrics.yaml

# Edit parametes like POSTGRES* and PGPOOL* variables according to your configuration

# Apply the modified deployment
kubectl apply -f pgpool-deploy-metrics.yaml

Verify Deployment:

kubectl get pods -l app=pgpool

Connect via Pgpool-II: Update your application to connect through the Pgpool-II service endpoint instead of directly to PostgreSQL.

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.
