⚠️ UNMAINTAINED - This repository is no longer actively maintained. Please use:

• CloudNative PG extension container images (see official documentation)
• cloudnative-pg/postgres-extensions-containers for the official CloudNative PG container extensions
• tripsolutions/postgresql-extensions-containers for simplified community-driven PostgreSQL extension container images

This repository contains the dockerfiles and scripts as well as the github actions to extend the postgresql container images from ghcr.io/cloudnative-pg/postgresql.

To build an image locally using docker, check out the repository and run the following command:

git clone

Then you can build the image using the following command:

docker build -t postgresql .

By default the image extends version 15.3 of the cloudnative-pg operand image. You can change this by providing a different version as build argument:

docker build -t postgresql --build-arg POSTGRESQL_VERSION=15.2 .

By default this image extends the base image with the timescaledb and cron extensions. To change this, you can provide a different list of extensions as build argument:

docker build -t postgresql --build-arg EXTENSIONS="timescaledb cron" .

The supported extensions are found in the official debian apt repositories under the package names postgresql-<pg_major>-<extension>. Timescaledb is handled separately as it is not available in the official debian apt repositories.

For the Timescaledb version you can also provide a different version as build argument:

docker build -t postgresql --build-arg TIMESCALEDB_VERSION=2.11.0 .

This repository contains a GitHub Actions workflow that builds the image and pushes it to the ghcr.io/<repository_owner>/postgresql repository. You can clone this repository to generate your own custom images directly in GitHub. The workflow is triggered manually and accepts the same build arguments as the local build.

The tags for the images are generated from the postgresql version and the extension list. The timescaledb extension is versioned. For example, the image for postgresql 15.3 with timescaledb 2.11.0 and cron extension would be tagged as 15.3-cron-timescaledb-2.11.0.
