Installing ``repo2docker``
==========================
repo2docker requires Python 3.4 and above on Linux and macOS. See
:ref:`below <windows>` for more information about Windows support.
Prerequisite: docker
--------------------
Install `Docker <https://www.docker.com>`_ as it is required
to build Docker images. The
`Community Edition <https://www.docker.com/community-edition>`_,
is available for free.
Recent versions of Docker are recommended.
The latest version of Docker, ``18.03``, successfully builds repositories from
`binder-examples <https://github.com/binder-examples>`_.
The `BinderHub <https://binderhub.readthedocs.io/>`_ helm chart uses version
``17.11.0-ce-dind``. See the
`helm chart <https://github.com/jupyterhub/binderhub/blob/master/helm-chart/binderhub/values.yaml#L167>`_
for more details.
Installing with ``pip``
-----------------------
We recommend installing ``repo2docker`` with the ``pip`` tool::
python3 -m pip install jupyter-repo2docker
For information on using ``repo2docker``, see :ref:`usage`.
Installing from source code
---------------------------
Alternatively, you can install repo2docker from source,
i.e. if you are contributing back to this project::
git clone https://github.com/jupyter/repo2docker.git
cd repo2docker
pip install -e .
That's it! For information on using ``repo2docker``, see
:ref:`usage`.
.. _windows:
Windows support
---------------
Windows support for ``repo2docker`` is still in the experimental stage.
An article about `using Windows and the WSL`_ (Windows Subsytem for Linux or
Bash on Windows) provides additional information about Windows and docker.

.. _jupyterhub_ready:
JupyterHub-ready images
-----------------------
JupyterHub_ allows multiple
users to collaborate on a shared Jupyter server. ``repo2docker`` can build
Docker images that can be shared within a JupyterHub deployment. For example,
`mybinder.org <https://mybinder.org>`_ uses JupyterHub and ``repo2docker``
to allow anyone to build a Docker image of a git repository online and
share an executable version of the repository with a URL to the built image.
To build JupyterHub_-ready Docker images with ``repo2docker``, the
version of your JupterHub deployment must be included in the
``environment.yml`` or ``requirements.txt`` of the git repositories you
build.
If your instance of JupyterHub uses ``DockerSpawner``, you will need to set its
command to run ``jupyterhub-singleuser`` by adding this line in your
configuration file::
c.DockerSpawner.cmd = ['jupyterhub-singleuser']
