1. Usage
========
To use Docker Builder, assemble the steps into a text file (commonly referred to
as a Dockerfile) and supply this to `docker build` on STDIN, like so:
To build an image from a source repository, create a description file called `Dockerfile`
at the root of your repository. This file will describe the steps to assemble
the image.
``docker build - < Dockerfile``
Then call `docker build` with the path of your source repository as argument:
``docker build .``
You can specify a repository and tag at which to save the new image if the
build succeeds:
``docker build -t shykes/myapp .``
Docker will run your steps one-by-one, committing the result if necessary,
before finally outputting the ID of your new image.
