Chainguard Container for pgwatch

pgwatch image.

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/pgwatch:latest

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

Deploying Pgwatch

Pgwatch can be deployed using the community managed pgwatch helm chart.

helm repo add pgwatch https://cybertec-postgresql.github.io/pgwatch-charts
helm repo update

helm install pgwatch pgwatch/pgwatch

In case the upstream link is not available, the helm chart can be manually cloned and installed.

git clone https://github.com/cybertec-postgresql/pgwatch-charts.git
cd pgwatch-chart/helm/pgwatch

helm install pgwatch -n pgwatch

To use the Chainguard pgwatch image instead of the default implementation, configure your values to use the hardened image:

#values.yaml
pgwatch:
  image: "cgr.dev/ORGANIZATION/pgwatch:latest"
# Additional configuration as required

Note that in some cases, the upstream helm chart does not automatically configure the crc-storageclass, causing deployment to hang. You can resolve this by manually configuring the storageClass.

#crc-storageclass.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
 name: crc-csi-hostpath-provisioner
provisioner: rancher.io/local-path
parameters:
 hostPath: /tmp/k8s-local-path
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer
allowVolumeExpansion: false

kubectl apply -f crc-storageclass.yaml

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.
