Logging of commands run inside container

[betsegaw]

There should be some way for the build container creator to highlight the commands he/she wants to run in the container. By doing so, instead of creating a container by snapshotting an existing container, we could instead do so by creating a Dockerfile that contains all the right none-interactive commands to run.

For example, instead of running

apt-get install git

you would run

log-command apt-get install git

This will, when you exit the container after building successfully, create a docker file that you can use to build the same enviroment
