Thanks for sharing!

Your setup seems sane and pretty close to what would be if you want to run the same thing on a single server.

It makes the code base in the original link looks like a proprietary duct tape spaghetti :P

I just recommend setup postscreen[1] and rspamd[2].

2. https://www.rspamd.com/

Another “serverless” route for Docker containers is to deploy the containers with Fargate which isn’t too hard and gives you autoscaling without having to re-architect your application for serverless. (And has correspondingly less vendor lock-in)
