CirrusLink Transmission/Engine module: where to find keystore

mateo.duren · June 3, 2025, 10:08am

Hi all,
we are working on an Ignition (8.1.48) implementation on OpenShift (Kubernetes) with the integration of the 3rd party modules:

CirrusLink MQTT Distributor 4.0.29
CirrusLink MQTT Transmission 4.0.29
CirrusLink MQTT Engine 4.0.29

We base the implementation on the icc2023-ignition-k8s project.

For the implementation we want to automatically insert the certificates into the ignition keystores, the question therefore remains: which keystores do these modules use?

CirrusLink MQTT Distributor 4.0.29 : the web UI keystore ssl.pfx (Secure MQTT Communication using SSL or TLS - MQTT Modules for Ignition 8.x - Confluence)
CirrusLink MQTT Transmission 4.0.29 : location unknown
CirrusLink MQTT Engine 4.0.29 : location unknown

Many thanks in advance, Mateo.

Hi all, with Wes Johnson's great help, I'm happy to inform that the above has been resolved.
I have added the (simplified) code example used for the solution to the CirrusLink forum, see: Transmission/Engine module: where to find keystore - #5 by mateo.duren - MQTT Modules - Cirrus Link Forum.

Hopefully this can help someone else in the future as well.
Kind regards, Mateo Duren
