remote machine and that no parsing of the Dockerfile happens at the

1. Usage
|

========
|
||||
|
||||
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.
|
||||
To :ref:`build <cli_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.
|
||||
|
||||
Then call ``docker build`` with the path of your source repository as
|
||||
argument:
|
||||
argument (for example, ``.``):
|
||||
|
||||
``sudo docker build .``
|
||||
|
||||
The path to the source repository defines where to find the *context*
|
||||
of the build. The build is run by the Docker daemon, not by the CLI,
|
||||
so the whole context must be transferred to the daemon. The Docker CLI
|
||||
reports "Uploading context" when the context is sent to the daemon.
|
||||
|
||||
You can specify a repository and tag at which to save the new image if the
|
||||
build succeeds:
|
||||
|
||||
``sudo 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.
|
||||
The Docker daemon will run your steps one-by-one, committing the
|
||||
result if necessary, before finally outputting the ID of your new
|
||||
image. The Docker daemon will automatically clean up the context you
|
||||
sent.
