Introduction

The concept of GGC stands for “Green Grass Computer”, the word: “Computer” also refers to any kind of device. This document will teach users how to configure, install, and deploy a GGC, as well as create and set up an Edge Device for the purpose of establishing a connection between the computer (device) and the 42Q portal to send data (payloads).

 

 

Prerequisites

• Only Linux is supported for the computer or device to install the Green Grass Core. The related shell scripts and test code only work on Linux systems (Windows is not currently supported).
• Python 3.8 or higher must be installed and configured to run the test code.
• Operating System and  Software requirements:
  • Linux kernel version 4.4 or later (Ubuntu 20.04 and CentOS 8.5).
  • Java Runtime Environment (JRE) version 8 or greater (included in the installation script).
  • Python version 3.8 for functions that use the Python 3.8 runtime (included in the installation script).
• Network requirements:
  A Region is an AWS region that hosts 42Q portal APIs. The Green Grass Core hardware needs to be able to access the following endpoints through specific ports:
  • [1].
  • [2].
  • greengrass-ats.iot.us-east-1.amazonaws.com. Ports:   8443, 443.
    • .iot.us-east-1.amazonaws.com. Ports:  8883, 8443, 443.
    • .credentials.iot.us-east-1.amazonaws.com. Ports: 443

 

 

Functional Description

There are three different functional components: CloudPrinting, MachineInterface, and DataIngestion.
