Generating a container from an image is easier than spending your vacation.
If a configuration change is needed that can be done only during creation of container then you should export image from the container and launch new container from the image with your desired change.
But sometimes you just cannot launch new container because either container id is getting used in many programs or restriction of space or any other irritating reason, now if you want to make that small change into the existing container, this tutorial helps you to solve this problem.

This tutorial helps to map a port of a running docker container. If a container is already running, you can still map a new port or update existing

𝗡𝗼𝘁𝗲 :
After following the tutorial, still you are not able to map the port of host system with the container, you need to check both config files again. If your added ports and parameters are not there, it means there was a syntax error in your parameters and that's why when you restarted the service, docker has reset both files in the original state.

Very helpful! I don't know why this can't be done in Portainer. I must be missing something.

Hello, dear, thank you for teaching ،me a question about how to expose several ports at the same time, for example from Ports 1-500 ??

[michaeladejoh]

Thank you for the presentation, could you please indicate a use case for this, since the container would be stopped and there would be downtime.

my /var/lib/docker/containers/ is empty
