Introduction

The guide covers the installation details which are related to Enterprise Applications on Lightweight 5G Telco Edge (EALTEdge) 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 K3s Cluster. 

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
• Center Node
• Edge Node

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

Note: EALTEdge 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 R4 - Test Documentation of Enterprise Applications on Lightweight 5G Telco Edge (EALTEdge) 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 MECM Cluster  with one or multiple MEC Host clusters.

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

1) Deployment Node

2) Center Node

3) Edge Node

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

Minimum Hardware Requirements

...

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

Recommended Hardware Requirements

...

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

...

1. git clone the ealt-edge repo, to download the software to install the EALTEdge Environment.

root@akraino-mec-0002:~# git clone "https://gerrit.akraino.org/r/ealt-edge"

2. go to CLI directory 

root@akraino-mec-0002:~#cd ealt/infra/cli/

root@akraino-mec-0002:~#chmod +x build _cli.sh

root@akraino-mec-0002:~#source build_cli.sh

root@akraino-mec-0002:~#cd ~/ealt-edge/ocd/infra/playbooks

Note: The CLI Commands to setup the environment should be executed only from above path.

3.  Edit the Configuration File : ealt-inventory.ini with the details of MECM and MEC Hosts. 

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

4. Execute the below command to install EALTEdge Environment 

root@akraino-mec-0002:~#ealt init all 

Above command will install the various component. Refer the below table for detail information. 

Other CLI Commands:

Command to Install only Edge Node

root@akraino-mec-0002:~#ealt init edge

Deploying Application Packages : Using CLI

This feature is currently not supported in Release 4.  Will be modified based on the upstream EdgeGallery Project's feature on the next Release.
