💨 💨 The Binder Project is moving to a new repo. 💨 💨

📚 Same functionality. Better performance for you. 📚

Over the past few months, we've been improving Binder's architecture and infrastructure. We're retiring this repo as it will no longer be actively developed. Future development will occur under the JupyterHub organization.

Thanks for updating your bookmarked links.

💨 💨 The Binder Project is moving to a new repo. 💨 💨

binder-build

Build Binder images from repositories

building an image from a repository

binder-build implements the build section of the Binder API defined in the Binder protocol.

The build server is responsible for converting the contents of GitHub repositories, or other sources, into Binder-compatible Docker images and associated runtime information (such as resource limits and hardware requirements). To do this, binder-build will search for configuration files in the repository and will select the most appropriate file to build from based on this prioritization (listed below in descending order; see (TODO: link) for complete descriptions of all configuration files):

  1. requirements.txt
  2. environment.yml
  3. Dockerfile

Once an image has been constructed from the repo contents, it can optionally be pushed to a Docker repository so that it will be accessible from any deployment backends. In our production environment, all images are pushed to the Google Container Registry.

The list of accepted image sources (currently only GitHub) can be extended by adding a handler to lib/sources.

constructing a template from an image

Docker images do not necessarily contain enough information about a Binder's runtime environment to properly it onto a container management system. As one example, resource limits and/or hardware constraints (such as a GPU requirement), need to be stored as additional metadata. With Binder, we construct a template from an image name and this auxilliary information, and we consider this to a fully-deployable environment specification.

Templates are automatically constructed with reasonable defaults when a build is started. The template API provides an interface for fetching all templates available for deployment, as well as for fetching a single template.

install

The simplest way to run the binder-build server is through the binder-control module, which manages the server's lifecycle and service (the database and logging system) dependencies. In binder-control, the build server can be started with with custom configuration parameters through

binder-control build start --api-key=<key> --config=/path/to/config

It will also be started with reasonable defaults through

binder-control start-all

If you'd prefer to use binder-build in standalone mode:

git clone git@github.com:binder-project/binder-build
cd binder-build
npm i && npm start

In standalone mode, the configuration will be loaded from conf/main.json

api

binder-build exposes both the build and registry portions of the Binder API, which are composed of the following endpoints:

usage

The best way to interact with the build server is through the binder-client. Once the client has been installed, all endpoints are accessible either programmatically or through the CLI. For example:

From JS

var binder = require('binder-client')
binder.build.status(<build options>, function (err, status) {
  ...
})

From the CLI

binder build status <image-name> --api-key=<key> --host=<host> --port=<port>
