nteract/commuter

com·mut·er

/kəˈmyo͞odər/ a person who travels some distance to work on a regular basis.

As commuters, we rush around from place to place all day. We go to work, school, and stores. We travel to locations near and far. Eventually, we return to our cozy home. :car: :office: :airplane: :tokyo_tower: :bullettrain_side: :department_store: :bus: :school: :bike: :city_sunset: :runner: :house_with_garden:

Like commuters, our data travels around too. Sometimes we need a notebook at work and other times at a client's site. Wherever and whenever you need your notebooks, commuter has you covered.

What is "commuter"?

As an opinionated nteract focused server, commuter reads notebooks from a local directory or Amazon S3, has a directory explorer to find notebooks, and provides a jupyter compatible version of the contents API. You determine where your notebooks should reside and where they should be shared. Flexibility and convenience.

Try commuter today and take your notebooks wherever you need them.

Installation

You may use whichever package manager (npm or yarn) best suits your workflow. The nteract team internally uses yarn.

npm install @nteract/commuter -g
# OR
yarn global add @nteract/commuter

Usage

Configure and run commuter with environment variables and commuter server.

Example local run (using a network file share!):

COMMUTER_LOCAL_STORAGE_BASEDIRECTORY=/efs/users/ commuter

Example S3 run:

COMMUTER_BUCKET=sweet-notebooks commuter

Environment Variables

General Environment Variables

Environment Variables for S3 Storage

Authentication to S3 is using CredentialProviderChain with default providers. This supports the most common ways of authenticating in AWS.

Development

Quick Start

1. git clone [email protected]:nteract/commuter.git
2. cd commuter
3. yarn
4. yarn dev
5. open http://localhost:4000

Dev Docker

A Dockerfile for a local dev server can be use as follows:

1. docker build --tag commuter:dev --file Dockerfile.dev .
2. Run this:

docker run \
    --init \
    --interactive \
    --tty \
    --rm \
    --publish 4000:4000 \
    --mount type=bind,source=(pwd),target=/app \
    --env COMMUTER_LOCAL_STORAGE_BASEDIRECTORY=/app/examples \
    commuter:dev

Tests

There are three ways you can run tests:

• If you have your environment set up, you can run tests locally via yarn test.
• This repository is also set up with GitHub Actions, a builtin CI system, which will automatically trigger test builds for multiple Node versions upon every push into this repository. You can then check out the results in the Actions tab.
• These GitHub Actions can be triggered locally using act, this way you don't have to have your JavaScript environment set up and you don't have to commit and push in order to run the tests remotely through GitHub.

Deployment

1. Install commuter cli yarn add @nteract/commuter
2. exec commuter - the service is typically wrapped inside daemontools

Deployment (Docker / Kubernetes)

A Dockerfile intended for Production use (suitable for Kubernetes or other container runtime) has been contributed. Instructions are below.

Note: there is no officially published Docker image at this time, you should publish it to your own image registry.

1. Build and tag image docker build --tag commuter:latest .
2. Image can be executed as follows:

docker run \
--publish 4000:4000 \
--mount type=bind,source=/home/username/work/commuter/examples,target=/examples \
--env COMMUTER_LOCAL_STORAGE_BASEDIRECTORY=/examples \
commuter:latest
