Our research lab, the FNNDSC, directs international collaborations on pediatric neuroimaging research. The data sharing platform for this research is ChRIS. We have implemented a solution for sharing DICOM data between "peer" instances of ChRIS using Orthanc, an open-source DICOM server. Here we describe our deployment of Orthanc on Red Hat OpenShift and other open-source contributions we would like to share with the Orthanc community.

ChRIS is now available on the NERC at https://app1.chrisproject.org. This deployment is a milestone comprising many improvements to ChRIS made in 2023.
To shrink a PersistentVolumeClaim (PVC) in OpenShift or Kubernetes, we need to:
OpenShift provides some observability features out-of-the-box, but which features are available depends on what your cluster admin has working and what you have access to. On the NERC, we are able to see container metrics in OpenShift Developer's built-in dashboard. To enable custom visualizations, metrics analysis, and alerting, we need to connect this data to an instance of Grafana which we control.
Currently, https://cube.chrisproject.org is being powered by a VM called fnndsc.childrens.harvard.edu
in the Boston Children Hospital network's DMZ. It's been working well for us through
the years, however its 480GB disk frequently runs out of space. For more
storage, easier deployments, and stability, we want to try migrating this instance
of the ChRIS backend to the NERC's OpenShift cluster.
