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.

If your docker container is running, now you want to update path of any mounted volume or you want to mount one more volume in the container, this is the guide for you.

𝗡𝗼𝘁𝗲 :
After following the tutorial, still you are not able to see the content of host directory in the container, you need to check both config files again. If your added paths 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.

This was asked in one of the devops interviews but without stopping the container. Brain teaser one 👍 some interviewer feels happy asking such R&D type questions. He deserves a position in NASA but stuck as interviewer.

Thank you sir, great video. help my brain easier

[jetskisnowboardski]

Thank you very much but it would have been great if the source and target directories were not the same path.

Can we add volume to running containers without stopping it ?

Hi and thank you for the video ! in my case, I have to share an NFS volume with my running platform. Behind this later 24 different docker container are running. Under which container, should I create my volume? Thank you !!
