terraform-aws-bitcoind

Bitcoin core daemon spun up on EC2 instance in AWS.

Recommended: If you want to use this in a public subnet, please take extra time to configure appropriate ufw/iptables.

Example Usage:

module "bitcoind" {
  source = "github.com/miketwenty1/terraform-aws-bitcoind"

  region                = "us-east-1"
  subnet_id             = data.aws_subnet.private.id
  ssh_key_name          = "bitcoin_ssh_key_example"
  sg_for_ssh_access_id  = data.aws_security_group.vpn.id
  bitcoin_version       = var.bitcoin_version
  instance_size         = var.instance_size
  alias                 = var.alias
  rpc_access_cidr       = var.rpc_access_cidr
}

Notable parameters: for a full list of configurable parameters please see variables.tf

subnet_id if using public subnet also set "enable_external_ip" to true, if using a private subnet (recommended) keep set to false.
enable_external_ip set to true if you want an external IP. If not set to true, you will need to use a jump box / vpn or other method to access your node.
sg_for_ssh_access_id should be used if you want to setup vpn or jumpbox access.
rpc_access_cidr recommended to set this to specific /32 cidr for your IP.
alias useful name to help avoid conflicts with named resources
bitcoin_version uses a tagged version of bitcoind in github.com/bitcoin/bitcoin

Mandatory parameters:

subnet_id (valid subnet id inside VPC with appropriate tag)
ssh_key_name (ssh key)
region (aws region)
rpc_access_cidr (cidr block ex: 0.0.0.0/0 is open to the internet, 1.2.3.4/32 is open to only ip 1.2.3.4)

Dependencies:

Have a VPC tagged with "key" bitcoin_terraform and "Value" enabled, This module will look to deploy the bitcoin node in this VPC. ssh_key_name needs to be created before running this module, and specified by name.

Cloudwatch Agent:

The cloudwatch agents are installed through SSM, if you want to setup custom, cloudwatch alarms this is outside of the scope of the module. Happy to accept PR's.

RPC and RMQ Access

Access sg's are created and sent to outputs, assign sg's these to resources that need access to RPC or ZMQ
