Analytics Dev Environment (Scala and Python)

This template repository facilitates the development of Scala and Python Jupyter Notebooks. The template is containerized to facilitate using it on different Machines.

It works on PCs (AMD64) and Macs using the latest Apple Silicon architecture (ARM64).

Requirements

You only need Docker.

How to use it

  1. Make sure you have Docker installed and running.
  2. Copy the environment variables file .env.example to .env Adjust the values as needed (see next section)
  3. Build and Run with VS code
    1. If you use VS code, open the menu (bottom left corner), and select Reopen in container. This will build the docker image, run the container, and open the root directory.
    2. Open any ipynb file in VScode and it will automatically open the Notebook view.
  4. Build and Run manually
    1. If you prefer to build and run the container manually, you can use docker-compose. 
      docker compose -f docker-compose.dev.yml up --build
    2. Once you've built it, you need to open another console, connect to the container. 
      docker compose -f docker-compose.dev.yml exec scala-docker-dev-env /bin/bash
    3. Run jupyter lab. After that, you can access it via a web browser. 
      jupyter lab --ip 0.0.0.0
