I need to add a wildcard certificate to Ignition so that the Kymera InfluxDB module can connect to the InfluxDB server that is running with a secure connection.

For context I have added the wildcard certificate to the Ubuntu server that Ignition is running on and I can use the API endpoints that InfluxDB has to verify that I can connect and communicate with the database server.

My understanding is that the Java Runtime will not use the certificate that the OS has though and that I need to add it to the Java Runtime separately.

Is there a documented process for adding a cert to the Java Runtime?
