PostgreSQL Container Images

Maintenance scripts to generate Immutable Application Containers for all available PostgreSQL versions (13 to 17) to be used as operands with the CloudNativePG operator for Kubernetes.

Images

We build three types of images:

• system
• minimal
• standard

Switching from system images to minimal or standard images on an existing cluster is not currently supported.

Minimal and standard images are supposed to be used alongside a backup plugin like Barman Cloud.

Images are available via GitHub Container Registry.

Currently, images are automatically rebuilt once a week (Monday).

System

These images are built on top of the Official Postgres image maintained by the PostgreSQL Docker Community, by adding the following software:

• Barman Cloud
• PGAudit
• Postgres Failover Slots
• pgvector

Minimal

These images are build on top of official Debian images by installing PostgreSQL.

Minimal images include minimal in the tag name, e.g. 17.2-standard-bookworm.

Standard

These images are build on top of the minimal images by adding the following software:

• PGAudit
• Postgres Failover Slots
• pgvector

and all the locales.

Standard images include standard in the tag name, e.g. 17.2-standard-bookworm.

SBOMs

Software Bills of Materials (SBOMs) are available for minimal and standard images. The SBOM for an image can be retrieved with the following command:

docker buildx imagetools inspect <IMAGE> --format "{{ json .SBOM.SPDX}}"

Testing image builds

Minimal and standard image builds can be tested running bake manually. You will need a container registry and a builder with the docker-container driver.

registry=<REGISTRY_URL> docker buildx bake --builder <BUILDER> --push
