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

Ansible-Playbook single command
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.

Image Modified

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 three. (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

ELIOT Master Node
HW Aspect	Requirements
# of Node(s)	A virtual machine hosted in any Cloud Provider having internet connectivity.
# of CPU	8
Architecture	x86_AMD64 or ARM64.
RAM	8 GB
Disk	120 GB ~ 512GB

eliot/blueprints/iotgateway/playbooks/eliot-inventory.ini

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:

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

root@akraino-mec-0001:~#ansible-playbook eliot-eg-aio-latest.yml -i hosts-aio --extra-vars "operation=install" -e ansible_user=root"
