How to run single nginx and multiple Laravel instances in the App Platform

We use Docker Compose for our Laravel application development. The two main Docker containers in our Compose configuration are:

• custom nginx Docker container with nginx micro-caching and request throttling - we would like to run a single instance of it

• custom PHP Docker Container for Laravel itself; we would like to scale it horizontally; nginx is to round-robin requests to multiple Laravel containers (or connect to a single connection point managed by DigitalOcean App Platform).

We are considering App Platform for deployment.

Is this setup possible with the App Platform?

We cannot eliminate nginx because of its role in micro-caching and request throttling; we would like Laravel not to do it because nginx is much more efficient and less resource greedy at these tasks.
