Secure Domain - Kubernetes

Hi,

I am trying to deploy Jitsi on Kubernetes with a Secure Domain, so that only a host is able to create meeting rooms. Up to now a basic Jitsi application without the security feature is up and running. Now, I would like to add the Secure Domain functionality. Is that possible without extending the the container configuration after the deployment, but with environment variables for the containers in the deployment yaml?

Thanks and kind regards
