At this point, why not use a wordpress container? With a minimalist theme, it would be way easier and faster to deploy, and still be blazingly responsive.

This level of complexity would've been acceptable if this was about deploying one's own netlify type of service for personal use. Otherwise, it's just way too complicated.

I'm currently working on a Django app, complete with a database, a caching layer, a reverse-proxy, a separate API service, etc. and still much simpler to deploy than this.
