How do I assign a port mapping to an existing Docker container

Question

I'm creating a new container from an image. Is there a way to assign a port mapping to an existing Docker container?

Can anyone help me with this?

Thanks

Below are some steps which you can follow:

First, stop the running container

docker stop container_id

Commit the container

docker commit container_id container_id2 

Container_id2 is a new image which is made from container_id2 container.

Try to re-run from the commited image

docker run -p 8080:8080 -td container_id2

I hope it will resolve your query.
