🚀 Deployment

This project assumes the Node machines will be AWS EC2 Ubuntu 20.4 based, with attached EBS Volume Machine specs should be at least 4 GB RAM, 4 Core CPU

Deployment Easily managed with ansible and you can override vars.yml file for certain variables values.

Regarding Deploying on Non AWS EC2 or EC2 without attached EBS Volume , you need to skip EBSVolumeMount tasks, as below

You may need to first set the value of this variable

volume_path: /dev/nvme1n1

For Running on machine without Attached EBS Volume

ansible-playbook main.yml --skip-tags EBSVolumeMount

All Data should be saved in below paths

/erigonVolumeData/
