Docker Container Tutorial #2 Making changes to docker images

In the second part of the Docker Containers Tutorials I demonstrate how changes can be made to a Docker image from within a container.
I then demonstrate how we can save these changes for future use.
This is done by running docker commit and saving a snapshot of the container.

What if I want to edit some code in the image? How do I do it? Say I have a web application, and I have pulled it from the docker hub and now I want to edit the index.js file inside of it. How do I do it?

3:16 I'm pretty new to docker. But wouldn't it be more correct to say you're making changes to the container?

Nice, but Im running into some issues on CentOS. I have pulled Nagios image and running container of it. Need to edit some files but vi or vim would not exist vithin the container. Well, wanted to install it but not even yum exists or is not mapped. If mapping needs to be done - any idea how? I have tried docker run -it <ID> -v /usr/bin ..but no joy there.. :)
