Introduction

The guide covers the installation details which are related to IOT Gateway Blueprint only. 

This guide provides the information for setting up the ELIOT Environment which includes ELIOT Manager and ELIOT Edge Node(s) (IoT Gateway) with details of software and hardware specifications for IoT Gateway Blueprint.

For Release-2.0 the scope of the guide covers two ELIOT deployments one is using Kubernetes and the other one using Kubeedge (Lightweight Kubernetes).  

The ELIOT Manager can be any Cloud Virtual Machine or Bare Metal having Ubuntu OS 16.04 and should be able to ping and SSH to the ELIOT Edge Node - IoT Gateway Node.  The Edge Node will be a Virtual Machine having Ubuntu 0S 16.04.

For Kubernetes setup Kubeadm tool is being used and for Container Networking Interface Calico plugin is being used.

For KubeEdge the connection between the ELIOT Manager and ELIOT Edge Node is being established via Web Socket. Currently KubeEdge does not support Container Networking Interface.

The common features which are application for both the ELIOT blueprints (IoT Gateway and SD-WAN / WAN/ uCPE) include ELIOT Portal , ELIOT Command Line Interface to bootstrap the ELIOT Cluster Installation.  These features are developed to ease the use and provide value added features for deployment, usage and monitoring of ELIOT Cluster.

Standard Deployment Overview

Deployment Type 1 : ELIOT IoT Gateway Deployment (Ubuntu & Cent OS)

Clone the ELIOT git Repo in ELIOT Manager node. It will create eliot folder, for executing the script go to $HOME/eliot/blueprint/iotgateway/scripts folder.

Edit the nodelist file with ELIOT Edge Node details.  Replace the below contents with the actual value with '|' separated. 

The below details are required in the setup.sh for sshpass command. The details are required by sshpass to login to ELIOT Edge Node from ELIOT Manager and execute the deployment scripts in the ELIOT Edge Node.

<eliotedgenodeusername>|<eliotedgenodeip>|<eliotedgenodepassword>

• eliotedgenodeusername – ELIOT Edge Node User Name. Example : akraino-slave-002

Verifying the Setup

Verifying ELIOT Kubernetes Deployment

The setup.sh script will install the ELIOT Manager and one ELIOT Edge Node ( depending on the number of edge nodes configured in the nodelist configuration file).  The script deploys the Kubernetes cluster and also installs EdgexX platform,  NGINX, Prometheus and cAdvisor and verifies whether the cluster by checking if EdgeX platform , NGINX Server is deployed successfully or not. If the deployment is not successful then the ELIOT setup script will exit.

After script execution is completed the Kubernetes cluster setup can be checked by executing kubectl get nodes. It will show both the ELIOT Manager and the ELIOT Edge Node as ready.

The setup script also deploys NGINX , cAdvisor , Edgex platform on the ELIOT Edge Node and verifies whether its deployed successful or not.

Developer  Guide and Troubleshooting

Uninstall Guide

Following two files can be used to revert the changes made by ELIOT deployment through kubernetes.

1. kubernetes_reset.sh:
   Purpose: There were certain issues occurring when the setup.sh file was executed again on the same setup. it threw error saying ‘the file/port in already in use’ when setup.sh file was executed again.
   Solution: A list was prepared for errors occurring on re-execution of setup.sh file. To fix them, some commands were executed manually to reset the changes. Once the list was finalized, these were consolidated in a .sh file. The file is in eliot/scripts/ folder.
   What it does:
   -- Resets kubeadm changes on both Manager and Edge Node machine.
   -- Installs iptables, ipvsadm required to restart kubectl service on both Manager and Edge Node machine.
   -- Restarts kubelet service on both Manager and Edge Node machine.
   -- Releases the port 10250 on both Manager and Edge Node machine.
   -- Deletes kubernetes file on Edge Node machine.
   
   
2. kubernetes_cleanup.sh
   Purpose: There was no file to rollback the changes done by setup.sh.
   Solution: A list of changes done by setup.sh file was prepared and then commands were written to rollback those installations and changes. The file is in eliot/scripts/ folder.
   What it does:
   -- Uninstalls Docker, Kubernetes, Kubectl, Kubeadm, Kubelet on both Manager and Edge Node machine.
   -- Resets kubeadm changes on both Manager and Edge Node machine.
   -- Installs iptables, ipvsadm required to restart kubectl service on both Manager and Edge Node machine.
   -- Restarts kubelet service on both Manager and Edge Node machine.
   -- Releases the port 10250 on both Manager and Edge Node machine.
