This repository automates keeping the SlicerDocker images in sync with the Slicer source tree.

It provides:

• Scripts to update the Slicer revision used in the Docker images.
• A GitHub Actions workflow to build and publish the images to Docker Hub.
• Legacy cron-based scripts for manual/server-side scheduling.

Published images are available on Docker Hub.

• https://github.com/Slicer/SlicerDocker
• https://hub.docker.com/u/slicer/

The Build and Publish workflow in this repository is scheduled to run daily at 04:30 UTC, roughly 30 minutes after the update-slicer-preview-branch workflow in the Slicer repository publishes the nightly-main branch.

You can also trigger the workflow manually from the GitHub UI with two inputs:

• slicer_ref: The Slicer branch or ref to build from (default: nightly-main).
• force_build: If true, rebuild and publish even if no changes were detected in SlicerDocker.

As an alternative to GitHub Actions, the original scripts can still be used to run updates manually or with cron.

1. Download scripts

git clone https://github.com/Slicer/SlicerDockerUpdate

2. Configure GitHub token used to update Slicer revision

cd SlicerDockerUpdate
echo "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" > SLICERDOCKER_GITHUB_TOKEN

3. Initialize

./setup.sh

4. Add a crontab entry

0 21 * * * /bin/bash /home/kitware/Packaging/SlicerDockerUpdate/cronjob.sh >/home/kitware/Packaging/SlicerDockerUpdate/cronjob-log.txt 2>&1
