SlicerDockerUpdate

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.

Usage

Automated (preferred)

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.

Legacy scripts (manual/cron)

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
