There is no direct way to see the DOI version in use. But you can do it in the pods directly.
- Log in to OSE, navigate to the DOI Project
- Navigate to Applications -> Pods -> doireadserver-*
- Click Actions -> Edit YAML on top right.
- Find the image node in the YAML; the version will be there in the path.
<Please see attached file for image>

Note : The hostname can be different from isl-dsdc.ca.com; also if the doireadserver pod is not available, use the readserver pod.
