Invalid port number substitution on restart (piped-frontend docker image)

[GitKepler]

Official Instance

• [ ] The bug is reproducible on the official hosted instance, or is API-related.

Describe the bug

Every time the frontend container (1337kavin/piped-frontend) is restarted, the port number in the NGINX configuration is modified as long as the configured port number ends with 80.

It looks like it is caused by this: https://github.com/TeamPiped/Piped/blob/8b8b823abdbcc3c57b455a390e6548444bcbacf8/docker/entrypoint.sh#L18:

The port number is replaced as long as it ends with 8080.

To Reproduce

Configure the docker container (1337kavin/piped-frontend) using the 8080 port number like this:

version: "3"

services:
    piped-frontend:
        image: 1337kavin/piped-frontend:latest
        restart: unless-stopped
        ...
        environment:
            BACKEND_HOSTNAME: ...
            HTTP_PORT: 8080

Expected behavior

The port number is only modified once
