Building Vault Cluster with a DynamoDB backend in AWS

This repo basically builds infrastructure to support Hashicorp's VAULT with a DynamoDB backend in AWS.

The repo is heavily dependent on bulding a special AMI with Vault binary installed and a couple helper scripts

Build Custom AMI

Clone the AMI Repo

git clone https://github.com/gastrogee/packer-aws-vault

Then export your access credentials

export AWS_ACCESS_KEY_ID=XXXXXXXXXXXXXXX
export AWS_SECRET_ACCESS_KEY=XXXXXXXXXXXXXXXXXXXXXXXX

Update the variable file with variables that are unique to your environment

vpc_id="vpc-XXXXXXXXXXXXXXX"
ami_user="<aws account number>"
instance_type="m5.large"
subnet_id="subnet-XXXXXXXXXXXX"

Then build the custom AMI in your account

packer build -var-file=variable.hcl server.hcl

Deploy infrastructure with Created AMI

Clone deployment repo

git clone https://github.com/gastrogee/terraform-aws-vault-cluster

Update variable.tf with variable unique to your environment or provide a variable file in .tfvars

Sample .tfvars

okta_org = "gastro"
okta_admin_groups = ["vault-prod-administrators", "vault-dev-administrators"]
pgp_recovery_keys   = ["jayz", "nas", "andre3000"]
vault_instance_count    = 3
instance_type   = "m5.2xlarge"
image_id    = "ami-XXXXXXXXXXXXXXXXXXXXX"

Then Run

terraform init 
terraform plan 
terraform apply
