Introduction

This guide covers both ELIOT IOT Gateway and ELIOT SD-WAN Use cases.

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

...

Software Prerequisites

• Virtual Machines preinstalled with Ubuntu 16.04
• root user created in the ELIOT Manager and ELIOT Edge Node
• SSH Server running in both the Nodes.
• sshpass installed in ELIOT Manager
• scp installed in ELIOT Manager and ELIOT Edge Node
• GO Lang installed in ELIOT Manager and ELIOT Edge Node (Note : This is required when we are setting up the ELIOT using KubeEdge.)
• git should be installed in ELIOT Manager and ELIOT Edge Node.

Virtual Deployment Guide

For Virtual Deployment two Ubuntu VM's are required one for ELIOT Manager and ELIOT Edge Node both the node should have internet connectivity , network interface and network connectivity between the two VM's.

...

root@akraino-slave-001:#git clone "https://gerrit.akraino.org/r/eliot"
root@akraino-slave-001:#cd eliot/scripts/
root@akraino-slave-001:~/eliot/scripts#vim nodelist

After editing the nodelist file , execute the setup.sh script.  The setup.sh script internally installs Docker and Kubernetes with Calico CNI plugin and RBAC for authorization.

root@akraino-slave-001:~/eliot/scripts#./setup.sh

ELIOT Deployment using KubeEdge

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

Edit the config_kubeedge file with ELIOT Manager and ELIOT Edge Node

The format of config_kubeedge file is as follows :

edgenodeusr=""

edgenodeip=""

edgenodepassword=""

masternodeusr=""

masternodeip=""

masternodepassword=""

root@akraino-slave-001:#git clone "https://gerrit.akraino.org/r/eliot" 
root@akraino-slave-001:#cd eliot/scripts/ 
root@akraino-slave-001:~/eliot/scripts#vim config_kubeedge
root@akraino-slave-001:~/eliot/scripts#./kubeedge_setup.sh

Snapshot Deployment Overview

There are two images created for Manager and Node machines. These are .qcow2 files. After deploying the VMs using these images, your setup for ELIOT is ready in minutes. Following is the link to the document to use these images:

Verifying the Setup

Verifying ELIOT Kubernetes Deployment

The setup.sh script will install the ELIOT Manager and one ELIOT Edge Node. 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 server on the ELIOT Edge Node and verifies whether its deployed successful or not.

Developer  Guide and Troubleshooting

Uninstall Guide

For Installation via Kubernetes:

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.

For Installation via KubeEdge:

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

1. kubeedge_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.

2. kubeedge_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 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.
