I have made my own Dockerfile for a apache server that starts with an standard parent file. See first line in my Dockerfile below:
FROM php:7.0-apache
EXPOSE 8080
This parent exposes port 80. Now have I exposed port 8080 in my Dockerfile. Only when I run it both ports are exposed.
It it posible to close the parent port 80 in my Dockerfile? As I cannot edit that file.
