How to configure ports in a container to exit?

Question

Docker

Hello, I can’t google a question about docker, everyone writes how to open a port when a request goes to a container, but I need to make a request from an http container to a page (on the Internet), do I need to open the port? and it will be 80/8080?
or what needs to be done to connect the connection from the container to the Internet?

Answer 1

Containers already have access to the outside.
