Introduction

...

• One-Click Deployment Node
• MECM Node / Center Node
• MEC Hosts 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.

...

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

1) Deployment Node

2) MECMCenter Node

3) MEC HostEdge Node

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

...

All the nodes should have internet connectivity , network interface and network connectivity between the  VM's. 

...

Once the execution is completed in console will see prompt "EALTEdge Environment Installed  , Components Install MECM and MEC Hosts Successfully"

...

Other Options:

To Install only MEC Host / Edge node
root@akraino-mec-0002:~# ansible-playbook ealt-all.yml -i ealt-inventory.ini --tags "edge" --extra-vars "operation=install"

...

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.

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

Snapshot Deployment Overview

...

Currently the verification is manually done. 

1. Login to the MECM Center Node and check whether K8S cluster is installed. 
2. Check the below mentioned components and services are running as Pods / Services in Kubernetes cluster
   1. PostgresSQL
   2. AppLCM
   3. Appo
   4. Inventory
   5. Apm
   6. MECM - FrontEnd
   7. Appstore
   8. Developer Portal
   9. Service Center
