This is a question to the team running this discourse instance. I’m assuming this instance is deployed on Kubernetes. If not, kindly dismiss this question. 
How is the team deploying Discourse on kubernetes? The build process is a little interesting for discourse as it seems you need to embed secrets into the image vs using env vars. I didn’t see official support for kubernetes listed but I did see posts like this one vaguely discussing how they did it.
We <3 kubernetes, but it’s one less thing we need to manage and can focus our needs on the project itself.
