This repository contains Dockerfiles and scripts to build base images for use within Stackable.

• boil (cargo boil)
• Docker including the buildx plugin
• Optional: OpenShift preflight tool to verify an image for OpenShift

Images are published to the oci.stackable.tech registry under the sdp organization by default.

Consult the boil README which contains a broad selection of different commands to build images locally.

There are individual GHA workflows (one for each image) which use a reusable workflow to build all specified versions for both amd64 and arm64. The workflow is triggered

• by pushes to main to produce 0.0.0-dev versions of the images,
• by a regular schedule to rebuild 0.0.0-dev versions of the images to avoid staleness,
• by tag pushes to produce (release candidate) images for a particular SDP release,
• and by manual workflow dispatches.

Images are patched using patchable. Consult the patchable README which contains a detailed usage guide.

To verify if a container image is compatible with OpenShift, run the following preflight command:

preflight check container oci.stackable.tech/sdp/<IMAGE>:<VERSION>-stackable<RELEASE_VERSION> --platform amd64
