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 K8s 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.

                    Figure: EALTEdge Deployment Architecture

Note: EALTEdge  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 R5 refer R6 - Test Documentation of Enterprise Applications on Lightweight 5G Telco Edge (EALTEdge) to  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 minimum number of logical nodes(all 3 nodes can be depployed on single VM or on multiple VMs ) 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

Software Prerequisites

• Virtual Machines preinstalled with Ubuntu 18.04 for MECM Node.
• Virtual Machines preinstalled with Ubuntu  18.04 for MEC Host Nodes
• root user created in the Deployment Node, MEC Node and MEC Host Node.
• SSH Server running in all the Nodes.
• Ansible > 2.10.7 installed in One Click Deployment Node (Jump Host)
• git installed in Jump Host.

Standard Deployment Overview
Jump Host Software Installations:
Login to the Jump Host and perform the below steps:

...

EALTEdge Installation Mode:

EALTEdge supports 2 Mode of installation: Multi Node and All-In-One (AIO) Node deployment.

AIO(All in One) mode: 

In this mode, all 3 nodes (OCD which is deployment node, Center node and Edge node) are deployed on single VM.

The logical deployment topology can be seen here.

Image Added

MUNO(Multi Node) Mode:

In this mode, all 3 nodes (OCD which is deployment node, Center node and Edge node) can be deployed on multiple VM.

This mode can have a OCD node deployed on a VM, Center node deployed on same OCD VM or on different VM and EDGE node deployed on different VM.

The logical deployment topology can be seen here.

• If you get authentication issue you can change the permission

             # Open file:  vi /etc/ssh/sshd_config

                  - PermitRootLogin yes

                  - PasswordAuthentication yes

              # Restart ssh service:

                  - sudo systemctl restart ssh.service

Vault documentation

**This document explains how to generate certificate by using vault and cert manager**
##Cluster Architecture
![](Vault_Cert_Arch)
##Make a cluster
##The Image try to put with reference to our environment, with reference to EALT Edge. Can make a picture where Vault will be running in MEC Host (as Root CA) , ##Cert Manager and Applications (App1, App2)
##1. Add helm repo
```
helm repo add hashicorp https://helm.releases.hashicorp.com
helm install vault hashicorp/vault
```
##2. Generate root token and Unseal Key
```
kubectl exec vault-0 -- vault operator init -key-shares=1 -key-threshold=1 -format=""
```
##Note: Root token we will use when we will login vault pod, Unseal Key and Root token will looks like below ex- 
##Unseal Key 1: QcTX47IacKidIjFWSrkGLiQG1fwaqoInEz0SqAZ7rMs=
##Initial Root Token: s.A0SXgscZxbCeJRd1AjsVzvUU

##Generated Unseal key need to put in below command then vault will start running as a pod
```
kubectl exec -ti vault-0 -- vault operator unseal <Unseal Key>
```
##Vault is initialised as a pod
##By using below command can login in vault pod
```
kubectl exec -it vault-0 -- /bin/sh
```
##Vault Initialisation and Configuration Steps
####Once we initialize the vault pod we get unseal key and root token, need to put the root token
```
vault login <root token>
```
##Enable the PKI secrets engine
##By default, the secrets engine will mount at the name of the engine. To enable the secrets engine at a ##different path, use the -path argument.
```
vault secrets enable pki
```
##Keep the value in sync with the comment. 30 days, Increase the TTL by tuning the secrets engine. The default value of 30 days may be too short
```
vault secrets tune -default-lease-ttl=2160h -max-lease-ttl=87600h pki
```
##Configure a CA certificate and private key. It can generate ##its own self-signed root
## ## ealtedge.com is  is a your common_name or base url
```
vault write pki/root/generate/internal common_name=ealtedge.com ttl ttl=8760h
```
##Update the CRL location and issuing certificates. These values can be updated in the future.
```
vault write pki/config/urls issuing_certificates="http://127.0.0.1:8200/v1/pki/ca" crl_distribution_points="http://127.0.0.1:8200/v1/pki/crl"
```
##It will allow your domain and subdomain
```
vault write pki/roles/my-role allowed_domains=ealtedge.com allow allow_subdomains=true max_ttl=8760h
```
##Generate a new credential by writing to the /issue endpoint with the name of the role
##The output will include a dynamically generated private key and certificate which corresponds to the ##given role
##The issuing CA and trust chain is also returned for automation simplicity
```
vault write pki/issue/my-role common_name=www.ealtedge.com
```

####Enabling AppRole in Vault
```
vault auth enable approle
```

...

##Now get ca certificate use below command
```
curl curl http://10.43.130.35:8200/v1/pki/ca/pem
```
##10.43.130.35 is your vault ip, need to replace with latest vault ip
