Deploy Ethereum nodes on AWS

This project provides a set of Ethereum nodes with an application load balancer in front of them for scaling requests.

Architecture

Application Load balancer forwards requests to three Ethereum nodes.

Requirements

• Install terraform

• Create an AWS account

• Install the awscli and define an AWS profile pointing to an AWS IAM role/user (administrator permissions).

• Define InfluxDB (used to collect metrics) password in AWS secret manager by running the below code:

  aws secretsmanager create-secret --region eu-west-1 \
  --name "influx/password" \
  --description "Influxdb password for user 'admin'." \
  --secret-string "YOUR_PASSWORD"
  
  

• Create an S3 bucket on your account to host the terraform state. Modify the backend.tf file to point to your bucket.

• Customize the variables in the terraform.tfvars file. The default variables will probably not be available.

• Customize the IP address ranges if required.

chain_data_backup_bucket = "eth-infra-nodes-backup"
infra_logs_bucket        = "eth-infra-nodes-logs"
eth_static_data_bucket   = "eth-infra-static-data"
chain_data_volume_size   = 1000
geth_public_key          = "geth_public_key_linux_9BA28146.key"
eth_node_instance_type   = "t3.2xlarge"

public_subnets_cidr      = ["192.168.0.0/28", "192.168.0.16/28", "192.168.0.32/28"]
