Introduction

The guide covers the installation details which are related to ELIOT Iot Gateway Blueprint.  

This guide covers detailed information of the various types of deployments, detailed steps and what are the various components it will install. In addition, the guide provides information on hardware requirements, prerequisite software and minimum hardware requirements. On successful deployment, Center and Edge Nodes will be installed. The number of nodes in Center cluster and Edge node in the cluster is configurable. 

The CENTER Node is a K8s Cluster and EDGE Node is a K8s Cluster worker node. 

How to use this document

The document includes details of prerequisites /pre-installation, installation and uninstalls steps. 

The prerequisites and pre-installation software and hardware should be ready before executing the installation steps.

In BP first release Two types of installation mechanisms are provided, as below 

1. Ansible-Playbook single command
2. Command Line Interface (CLI)

Deployment Architecture

The Deployment Architecture consists of the following nodes

• One-Click Deployment Node
• ELIOT Master Node
• IotGateway Node

Note: For Development environment two nodes  is sufficient, where one node plays a dual role of One-Click Deployment Node and  Master Node with other as IotGateway Node.

                                                 Figure: ELIOT Deployment Architecture

Note: ELIOT IotGateway Blueprint Deployment has been tested on Cloud VM and is not tested on Bare-Metal Environment. Though, theoretically deployment should work  in bare metal,  provided hardware and software prerequisites are met. Kindly refer R5 - Test Documentation of Edge Lightweight IotGateway (ELIOT) to get details on the tested deployment.

Pre-Installation Requirements

Hardware Requirements

The number of Hardware requirements depends mainly on the Use Case Scenario and the enterprise scale. A use case can have one Deployment node, ELIOT Master or controller node  with one or multiple IotGateway nodes.

The minimum number of nodes required for a complete ELIOT Topology is 2. (Bare-Metal or Virtual Machines) 

1) Deployment Node

2) ELIOT Master

3) ELIOT IotGateway node

Note: The Hardware details provided are of Virtual Machine configurations.

Minimum Hardware Requirements

Note: The above specifications are given considering the ELIOT CI / CD environment. User can try lower configuration considering lightweight components being used.

Recommended Hardware Requirements

Software Prerequisites

• Virtual Machines preinstalled with Ubuntu 18.04 for MECM Node.

Virtual Deployment Guide

For Virtual Deployment minimum 2 Virtual machines, following are the virtual machines(OCD and Master on same node) and their usage

All the nodes should have internet connectivity , network interface and network connectivity between the  VM's. 

In this release to install the ELIOT environment. 

i)  ELIOT Deployment using Ansible-Playbook single command

Standard Deployment Overview

Jump Host Software Installations:

Login to the Jump Host and perform the below steps:

1. Install Ansible > 2.10.7
2. Install git
3. Install python3 and pip3

Jump Host Pre-Configurations for MECM Components Installation 

Login to the Jump Host and perform the below configuration steps (Steps : as below-

1. Generate public key :

• ssh-keygen -t rsa

2. Setup password-less login - 

• If you get authentication issue you can change the permission

             # Open file:  vi /etc/ssh/sshd_config

                  - PermitRootLogin yes

                  - PasswordAuthentication yes

              # Restart ssh service:

                  - sudo systemctl restart ssh.service

For EdgeGallery AIO mode:

Login from ocd to center and ocd to edge in a single node.

•  sshpass -p <password> ssh-copy-id -p <ssh-port> -o StrictHostKeyChecking=no root@<node_ip>

For EdgeGallery Muno mode:

Login from ocd to center in a controller node

•  sshpass -p <password> ssh-copy-id -p <ssh-port> -o StrictHostKeyChecking=no root@<controller-node_ip>
•  sshpass -p <password> ssh-copy-id -p <ssh-port> -o StrictHostKeyChecking=no root@<edge-node_ip>

Login from ocd to edge in a edge node

•  sshpass -p <password> ssh-copy-id -p <ssh-port> -o StrictHostKeyChecking=no root@<controller-node_ip>
•  sshpass -p <password> ssh-copy-id -p <ssh-port> -o StrictHostKeyChecking=no root@<edge-node_ip>

3.  These command are require in both AIO and MUNO(Controller and Edge Node )  mode.

    cp -p /etc/passwd  /etc/passwd.bkp

    cp -p /etc/group  /etc/group.bkp

    id ubuntu

    groupmod -g 600 ubuntu

    id ubuntu

Installing Mode : ELIOT using Ansible-Playbooks

1. git clone the eliot repo, to download the software to install the ELIOT Environment.

root@akraino-mec-0001:~# git clone "https://gerrit.akraino.org/r/eliot"

2. go to the below directory 

root@akraino-mec-0001:~# cd eliot/blueprints/iotgateway/playbooks

3. Modify the Configuration File : eliot-inventory.ini with the details of Master and Edge/IotGateway Nodes. 

root@akraino-mec-0002:~# vi eliot-inventory.ini

For Edge Gallery installation:

• Select one of Multi Node Inventory Mode (MUNO-Mode) or All in one mode (AIO mode) and install it.

MUNO-Mode:

Execute the below command:

cd eliot/blueprints/iotgateway/playbooks

ansible-playbook -i muno-config/controller/hosts-muno-controller eliot-eg-muno-controller.yml --extra-vars "operation=install" -e "ansible_user=root"

ansible-playbook -i muno-config/edge/hosts-muno-edge eliot-eg-muno-edge.yml --extra-vars "operation=install" -e "ansible_user=root"

For AIO mode:

Execute the below command

cd ealt-edge/ocd/infra/playbooks

ansible-playbook eliot-eg-aio-latest.yml -i hosts-aio --extra-vars "operation=install" -e "ansible_user=root"

FOR ELIOT Stack:

Execute the below command 
Setup environment - 

ansible-playbook eliot-all.yml -i eliot-inventory.ini --extra-vars "operation=install"

Once the execution is completed in console will see prompt "ELIOTEdge Environment Installed  , Components Install ELIOT Master and EDGE Nodes Successfully"
