We have implemented now a simple wrapper around the karaf session which wraps the response in a json property (multiline) and sets up a JAAS context. Haven’t done much testing but was fairly easy. It uses some internal framework so maybe I need to rewrite it to share..

Bernd

Any REST wrapper for the shell would require Karaf commands to smartly use PrintStreams vs System.out (etc) directly. Gesendet: Samstag, Dezember 13, 2025 2:48 AM

** WARNING: MASSIVE SECURITY RISK AHEAD **
If the commands are written appropriately, it is doable by creating a new session programmatically — however, I doubt you could create proper REST since the output type of the commands can be whatever or nothing and there isn’t a formal way to pass that information from the command API to the REST API.
Also, keep in mind that the ssh layer performs authn/authz checking and any REST endpoint would need to implement that correctly.

It looks like the deployer API Managed artifacts and deals with bundles, but I need a REST Gateway to custom OSGi Shell commands (not related to Karaf management).

(I guess it will be possible to have a simple „execute command and return output“ Gateway servlet, so we will go with that.
