Best way forward for installation on ClearOS

I’m helping out at a eye docter and have recently setup a HPE ClearOS (CentOS derivative) server with raid 5, samba, sqlserver and that has the capacity and diskspace to act as a PACS server.

Currently I have a test installation on a windows machine with a drive map for the dicom files, but ideally I would like to run all of it on the linux box.

I was thinking of installing the lsb compatibility and use the lsb release, but it is not clear to me how to proceeed to actually get it installed.
Is there a linux/unix manual somewhere ?

this page gives a detailed overview how ClearOS relates to CentOS / RHEL / Fedora …

Or would it be better to try the fedora route ?

thanks for any advise and insight ?


Although not listed in the marketplace for ClearOS. There apparently is docker support recently added. I have installed docker and are using the docker image as a test now.

Is the functionality the same with or without docker ? Looking to use the worklist function and the archiving …


Modern container runtimes like Docker typically deal with userspace
process isolation only. Functionality (and performance) is thus
identical insofar as you configure the containers to provide the
isolated process with the resources it needs to cater for your
requirements (e.g. a persistent "volume" for non-volatile storage, a
virtual bridge network adapter for connectivity, etc).

Regarding worklists, see the official documentation of the sample
plugin[1] then the configuration of the relevant container setup

Regarding archiving, nothing special needs to be done (assuming you
mean either the "archive" sub-resource of most Orthanc resources or
simply the use of Orthanc storage for long-term archiving).

See setup samples[3].



As ClearOS is a CentOS derivative, this GNU/Linux distribution should be LSB compatible (Linux Standard Base), and you should be able to directly run the LSB precompiled binaries of the Orthanc project on ClearOS (i.e. without using Docker).

These LSB binaries can be downloaded at the following location:


Hi Sébastien,
This is great. We are a Windows and CentOS shop, didn’t know LSB precompiled binaries were available. Gave them a quick test so far and all good on CentOS, thanks!

Thank you for your response. I am not that familiar with LSB and since i have a Microsoft SQL server also running on that clearos box, i thought it might be wise to take the docker container approach and avoid interference with my production mssqlserver. Better safe than sorry kinda thing…

I am connecting different machines without much documentation but overall orthanc is stable and i just need to figure out the dicom tags to store in the emr.
I am a happy trooper :slight_smile:


I have orthanc docker image running on ClearOs with a permanent storage volume.

I would like to also generate the worklists on the server.

I understand I need dump2dcm toolkit script running to generate the .wl file from a file generated by an external (db) script,
but I’m unsure on how to proceed inside or outside of docker and which release/installation method would be best.

Any pointers ?


Regarding worklists, check out the Orthanc Book:



did look in the book but wasnt getting any wiser.

Since then i have found the pydicom docker image which seems like a logical fit with my orthanc docker image :sunglasses:

I was able to use the dcmdump on the supplied .wl test files so i think i have all the pieces of the puzzle in order to get worklists going.



The Orthanc Docker image derives from Debian 7, which makes it almost trivial to get access to the “dcmdump” tool, by installing the “dcmtk” package:

$ sudo docker run -i -t --rm --entrypoint=bash jodogne/orthanc-plugins:1.4.1

dcmdump --version

bash: dcmdump: command not found

apt-get update && apt-get install -y dcmtk

dcmdump --version

$dcmtk: dcmdump v3.6.0 2011-01-06 $

dcmdump: Dump DICOM file and data set
