By default, the EXPOSE instruction does not expose the container’s ports to be accessible from the host. In other words, it only makes the stated ports available for inter-container interaction. For example, let’s say you have a Node.js application and a Redis server deployed on the same Docker network. To ensure the Node.js application communicates with the Redis server, the Redis container should expose a port. If you check the Dockerfile of the official Redis image, a line is included that says EXPOSE 6379. This is what allows the two containers to talk with one another. Therefore, when your Node.js application connects to the 6379 port of the Redis container, the EXPOSE directive is what ensures the inter-container communication takes place.

you can't publish a port to your host via Dockerfile. you should do that via the docker-compose.yml file or via the command line. after your image gets built with the Dockerfile then you can use the command below to publish port 5000 of your container to port 5000 of your host.
