Installation High-Level Overview
In ELIOT Release 1.0 for deployment 2 Ubuntu 16.04 Virtual Machines are used.
The steps includes to setup the following two environments To setup the complete ELIOT IoT Gateway Environment need to execute one script which will bootstrap the installation and provide the complete ELIOT Cluster on which applications can be deployed.
In Release 2.0 installations steps are provided to setup following ELIOT IoT Gateway Environments :
- ELIOT Deployment using Kubernetes. IoT Deployment on Ubuntu OS 16.04
- ELIOT IoT Gateway Deployment on Minimal OS (Tailored OS based on Cent OS)
- ELIOT Deployment using KubeEdge (Lightweight Kubelet)

Standard Deployment Overview
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
- eliotedgenodeip – ELIOT Edge Node IP. Example : 159.123.1.50
- eliotedgenodepassword - ELIOT Edge Node Password used in setup.sh script to login to ELIOT Edge node from ELIOT Manager to execute scripts in ELIOT Edge node.
The ELIOT Edge Node should be reachable from ELIOT Manager and ssh should work from ELIOT Manager to ELIOT Edge node as a prerequisite.

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.

ELIOT IoT Gateway Deployment (Tailored OS)
Clone the ELIOT git repo Repo in ELIOT Manager node. It will create eliot folder, for executing the script go to $HOME/eliot/blueprint/iotgateway/scripts folder.
The ELIOT Edge Node (IoT Gateway Node) is a tailored OS Virtual Machine. (Tailored OS used in the environment is created using steps mentioned in the link ELIOT Tailored OS Creation Document

ELIOT IoT Gateway Deployment using KubeEdge
...
| Info |
|---|
Note: We are running setup.sh without updating nodelist file. This is required to setup k8s master node which is required as a pre-requisite prerequisite for kubeedge KubeEdge setup in kubeedgeKubeEdge_setup.sh → we are currently using V1.1.0 version of kubeedge ( latest stable version package ) PATH_OF_KUBEEDGE variable has to be set with path of the kubeedge folder. This will be "eliot/blueprints/iotgateway/scripts/kubeedge" KUBEEDGE_VERSION_ETC → variable has to be set with "/etc/kubeedge-v1.1.0-linux-amd64/" since we are using 1.1.0 version of kubeedge |

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