Configuration of web service URL path

[hackermd]

When the archive sits behind a reverse proxy, the values of the RetrieveURL attributes included in search results may be incorrect and bulk data cannot be retrieved.

How can the path of the Service URL be configured to use an alternative path (e.g., /dicomweb instead of /dcm4chee-arc/aets/DCM4CHEE/rs)? It would be great if this would be configurable via an environment variable (e.g., DICOM_WEB_SERVICE_URL_PATH)

s. Archive Device attribute:

Name	Type	Description (LDAP Attribute)
Remap Retrieve URL	string	Remap Retrieve URL used in QIDO-RS and WADO-RS Metadata responses. Optionally prefixed with “[]”. E.g.: “[cache-proxy]http://cache-proxy:8080”. If absent or if the specified does not match, scheme and server authority of the QIDO-RS or WADO-RS request URL are used. (dcmRemapRetrieveURL)

Thanks @gunterze. I was wondering whether this attribute (and potentially other archive device attributes) could be configured during the container build process, for example via an environment variable? Having to go through LDAP, one has to wait until the entire system is up and running (including the LDAP container), which complicates container orchestration.

[gunterze]

You may provide a LDIF file which set this attribute to a particular value, map it into the LDAP container - or build your own LDAP docker image based on the provided one, including the LDIF file already into the docker image - and append the file path to passed LDAP_INIT_CONFIG.

@gunterze could you please provide a concrete example for the LDIF file?

What dn do I need to use to change the attribute?

dn: dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
changeType: modify
replace: dcmRemapRetrieveURL
dcmRemapRetrieveURL: http://localhost:8008/dicomweb

Gives me ldap_modify: No such object (32)

Never mind @gunterze. I forgot to provide the default configuration.

[hackermd]

However, the dcm4chee-arc/aets/DCM4CHEE/rs path remains in metadata values of QIDO-RS and WADO-RS response message payloads. In this case, the values have prefix http://localhost:8008/dicomweb/dcm4chee-arc/aets/DCM4CHEE/rs/studies. I need that prefix to be http://localhost:8008/dicomweb/studies instead. What am I missing?

[hackermd]

I tried setting dcmWebServicePath:

dn: dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
changeType: modify
replace: dcmWebServicePath
dcmWebServicePath: /

But that doesn't work.

@gunterze it would be great if you could provide a complete example.
