Is SUPERSET_PORT correctly set to 8080 in the Dockerfile? Or should it be 8088? We are having trouble connecting via wget to superset from outside the container, when we can connect from inside.

@buzzware open a specific issue for that, since it's not totally related with this issue

@dpgaspar Primarily I just want an experienced opinion on whether SUPERSET_PORT is wrongly set to 8080 just like the documentation error this issue refers to.
