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
