We are using DigitalOcean’s App Platform. So far our Dockerfile started NodeJS server which worked. Now we added Nginx in the Dockerfile as the first responder to proxy our Rust and old NodeJS server. It works perfectly on every machine we have tried on, but not on DigitalOcean’s App Platform. There simple
const app = express() app.listen(8084, () => …) just dones’t work.
Is this some kind of … limitation of the platform?
We have exposed only one port 8081 for Nginx. Internally Rust runs on 8085 and NodeJS should run on 8084.

App Platform can only expose 1 port to the outside world which needs to run HTTP traffic.
However, internal ports can be added to the app spec. Your rust port could be run on 8085 and accessed by the components locally. Here’s documentation on internal services.
If both services need to be accessed publicly then they should be separated into distinct components.
