Yeah, it's basically this. I'm running this as an initContainer for my K8s-based deployments. Took me a bit to get everything going, but my stack is pretty much similar to OP's article, although not quite as advanced in the automated-deployment of containers and monitoring. I'm not at a position where usage needs heavy monitoring because I'm still in the pre-launch phase of things and I'm using this side project to learn stuff I've yet to get experience with at multiple companies.
