[biblia19]

Description of the feature you are requesting:
User can easily to change published port with .env file
Maybe duplicate with [Feature] Specify ports for all services in the .env file

Describe the solution you'd like

.env

...
# Bottom of the file
# Custom Port Configuration
NGINX_PORT=18082 # (or whatever you want)

docker-compose.yml

version: "3.9"

services:
...
  nginx:
    ...
    ports:
      - ${NGINX_PORT:-8082}:80

Additional context
User can check the port with docker compose config | grep published

Is there any particular reason why you prefer doing it from the .env rather than the compose.yml itself?

[biblia19]

Nothing special, but I think that users as possible only change the environment variable in .env without change docker-compose.yml. Because when developer tracked the bug from other users, you need to read all user-custom docker-compose.yml everytime. And I want to change the nginx port easily without read all docker-compose.yml.
Or I just refer other repository like [mattermost/docker] env.example

If you do not want to plan these feature, just close the issue please.
