Chia farmer infrastructure for AWS

Description

From the website: Chia is a modern cryptocurrency built from scratch, designed to be efficient, decentralized, and secure. Here are some of the features and benefits:

What this repo is

This repo contains deployment configuration and infrastructure-as-code for deploying systems designed to farm Chia.

This repo is still in its early stages, so don't expect it to be 1-click or extremely easy to set up.

Customization

This is a public repo, but it's being used to instantiate private infrastructure in AWS. So, some information is necessarily gitignored. In the terraform/ directory, you must provide your own configuration via:

In *.private.tfvars files, define the following variables:

availability_zone
ssh_key_name
ssh_public_key
home_ips

In *.private.tf files, define your AWS Terraform provider and any desired statefile backend, e.g.:

terraform {
  backend "s3" {
    bucket  = "your-tf-state"
    key     = "terraform.tfstate"
    region  = "us-east-1"
    encrypt = true
  }
}

provider "aws" {
  region = "us-east-1"
}

Deployment

Download Terraform
Ensure your AWS credentials are configured properly, via aws configure.
From the terraform/ directory, run terraform apply. Pass in any tfvars files with -var-file=....
Once the instance is provisioned, find its DNS name and connect to it:

$ aws ec2 describe-instances --filters "Name=instance-state-name,Values=running"
$ ssh ec2-user@your-instance-dns

From the instance, perform the following steps to setup the environment:

# Security updates
[ec2-user@ip-10-0-0-23 ~]$ sudo su -
[root@ip-10-0-0-23 ~]# yum update -y

# Dependencies
[root@ip-10-0-0-23 ~]# yum install docker htop tmux -y
[root@ip-10-0-0-23 ~]# systemctl start docker

# Format the EBS volumes
[root@ip-10-0-0-23 ~]# mkdir /mnt/scratch /mnt/plot1
[root@ip-10-0-0-23 ~]# mkfs.xfs /dev/nvme1n1
[root@ip-10-0-0-23 ~]# mkfs.xfs /dev/nvme2n1
[root@ip-10-0-0-23 ~]# mount -t xfs /dev/nvme1n1 /mnt/scratch
[root@ip-10-0-0-23 ~]# mount -t xfs /dev/nvme2n1 /mnt/plot1

Start a Docker container with the chia-blockchain runtime environment.

[root@ip-10-0-0-23 ~]# docker run --rm -it --entrypoint=/bin/bash --volume=/mnt/scratch:/mnt/scratch --volume=/mnt/plot1:/mnt/plot1 bosgood/chia:dev
root@059bbf1b2ac6:/usr/local/chia-blockchain# chia init
root@059bbf1b2ac6:/usr/local/chia-blockchain# chia keys generate
# Copy the mnemonic key phase this command outputs, and either write it down or save it in a password vault somewhere

Create a Chia plot using the scratch space /mnt/scratch, with a final directory of /mnt/plot1:

root@059bbf1b2ac6:/usr/local/chia-blockchain# chia plots create -k 35 --tmp_dir /mnt/scratch --final_dir /mnt/plot1

TODO: Finally, start the service

Notes

The CoreOS configuration is experimental and not currently in use.
The Dockerfile is already being built and published to bosgood/chia:dev, so it isn't necessary for you to re-publish unless you want to customize it.
