title: Copying local git config into docker container
body: <p>I'm using both docker and docker-compose to host what for the most part is a LAMP stack. I'd like to be able to use git inside one of my containers without it asking for my user.email and user.name on push after I build. Along with other things such as my push.default and branch settings. Is there any good way to have docker or docker-compose copy the results of <code>git config --list</code> to a file in the container, which I can then use with my entrypoint to setup the git config.</p>
