It allows you to package up an application with all of the parts it needs (such as libraries and other dependencies) and ship it all out as one package, allowing for the portable sharing of containers across different machines.
You can bind multiple ports as well with a single container, but make sure to EXPOSE all ports in Dockerfile before building the image. $ docker run -it -p 8080:80,8081:443 image_name If you need to bind port with the specific interface of host machine define its IP address as below.
The EXPOSE instruction informs Docker that the container listens on the specified network ports at runtime. EXPOSE does NOT make the ports of the container accessible to the host. To do that, you must use either the -p flag to publish a range of ports or the -P flag to publish all of the exposed ports.
