What is the difference between “expose” and “publish” in Docker?

Question

I\'m experimenting with Dockerfiles, and I think I understand most of the logic. However, I don\'t see the difference between \"exposing\" and \"publishing\" a port in this

Answer 1

EXPOSE is used to map local port container port ie : if you specify expose in docker file like

EXPOSE 8090

What will does it will map localhost port 8090 to container port 8090
