Let me ask you a question. I ran a container.helloTo map the host port and container port through the -p parameter.

sudo docker run -d --name hello -p 8080:8080 -m 268435456 ubuntu:14.04 bin/bash -c "while true;  do echo hello $(date);   sleep 2;  done"

Then a new image is generated by the commit commandsudo docker commit hello hello-image.
Then, based on the image, use thedocker run -d hello-imageRerun a new container (the -p parameter is not specified at this time).
The newly generated container has no port mapping, and also has no -m parameter information previously set by the container.

My question is: How do you understand that the newly generated container does not have two pieces of information: mapped ports and memory limits? What parameters belong to the container and what parameters belong to the mirror image?
