Ignoring Files During Docker Build

As the resident Docker expert, President Squawk and the Radar Board have requested your aid in ignoring a few configuration files in the ~/content-dockerquest-spacebones/salt-example/salt-master/ directory. Populate the included .dockerignore file to prevent docker build from including incorrect or unneeded files in the build. Once complete, only docker-entrypoint.sh should live on the new image.

Once you have populated .dockerignore, build a new Docker container image named salt-master with the tag :deb.
