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-bitnami: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 pgpool2-bitnami Image is comparable to the bitnami/pgpool Image from Docker Hub. However, the Chainguard image contains only the minimum set of tools and dependencies needed to function. This means it does not include things like a shell or a package manager.

Getting Started

You can use the Helm chart for Bitnami PostgreSQL HA to deploy Chainguard's pgpool2-bitnami image.

To do so, you could use a values.yaml similar to this:

global:
  # https://github.com/bitnami/charts/issues/30850
  security:
    allowInsecureImages: true
  postgresql:
    database: postgres
    password: SecurePostgresPassword123
    repmgrDatabase: repmgr
    repmgrPassword: SecureRepmgrPassword123
    repmgrUsername: repmgr
    username: postgres

pgpool:
  livenessProbe:
    initialDelaySeconds: 60
    periodSeconds: 10
    timeoutSeconds: 10
    failureThreshold: 10
  readinessProbe:
    initialDelaySeconds: 60
    periodSeconds: 10
    timeoutSeconds: 10
    failureThreshold: 10
  adminUsername: pgpooladmin
  adminPassword: SecureAdminPassword123
  configuration: |
    backend_hostname0 = 'postgresql-ha-postgresql-0.postgresql-ha-postgresql-headless.default.svc.cluster.local'
    backend_port0 = 5432
    backend_weight0 = 1
    backend_data_directory0 = '/bitnami/postgresql/data'

    enable_pool_hba = on
    pcp_listen_addresses = '*'
    pcp_port = 9898
  replicas: 1
  image:
    registry: <registry>
    repository: <repository>
    tag: <tag>

postgresql:
  replicaCount: 1

The image section should be updated to reference the correct registry, repository, and tag.

Install Helm chart using the following commands:

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update
helm install postgresql-ha bitnami/postgresql-ha -f values.yaml

Once the pods are running you can verify connectivity by accessing the pgpool pod and running a command like the following:

kubectl exec -it postgresql-ha-pgpool-67949f746b-sfkpw -- bash -c "PGPASSWORD=\$PGPOOL_POSTGRES_PASSWORD psql -h localhost -U postgres -c 'SELECT 1;'"

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.
