This quickstart consists of one microservice:

Jupyter: Runs Jupyter Julia notebook.

Follow along below to get the setup working on your cluster.

Prerequisites

• Ensure that you have the hasura cli tool installed on your system.

$ hasura version

Once you have installed the hasura cli tool, login to your Hasura account

$ # Login if you haven't already
$ hasura login

• You should also have git installed.

$ git --version

Getting started

$ # Run the quickstart command to get the project
$ hasura quickstart anirudhm/julia-jupyter-notebook

$ # Navigate into the Project
$ cd julia-jupyter-notebook

Deploy app

$ # Ensure that you are in the julia-jupyter-notebook directory
$ # Git add, commit & push to deploy to your cluster
$ git add .
$ git commit -m 'First commit'
$ git push hasura master

Once the above commands complete successfully, your cluster will have jupyter service running. To get their URLs

$ # Run this in the julia-jupyter-notebook directory
$ hasura microservice list

Exploring Jupyter

Open the Jupyter service

Head over to the EXTERNAL-URL of your jupyter service.

Authentication

$ # Run this in the julia-jupyter-notebook directory
$ hasura ms logs jupyter

Copy the authentication token from the logs and enter it in the jupyter UI above.
