Deploy Simplicite image to a managed Ovh infrastructure

On an Ovh-managed infrastructure that we don’t have a hand for, when deploying the simple image, I have a Starting userland proxy error: listen tcp 0.0.0.0:80; bind: address already in use.
Indeed, it is apache that makes reverse proxy via http and the port is 80.

Is it possible to change ports? What settings can be set?

The relevant documentation for the deployment recipes of Docker images behind a reverse proxy is: https://docs.simplicite.io/documentation/90-operation/docker.md#ports and https://docs.simplicite.io/documentation/90-operation/docker.md#reverseproxy

The various strategies depend on the reverse proxy type & configuration
