DigitalOcean Terraform NodeJS server

This repo is an attempt for setting up a fully configured DigitalOcean infrastructure for a NodeJS server with a database hosted on a different droplet within a VPC and a frontend

---

Setup

Custom Droplet image

This project uses Packer from Hashicorp to create custom droplet images with everything setup.

The Packer configuration uses a variable file for its secrets: packer-secrets.json. You'll find an example file in this repo for the structure to follow.

Build your snapshot

To build your snapshot using Packer:

packer build \
  -var 'size=s-1vcpu-1gb' \
  -var-file 'packer-secrets.json' \
  packer.json

Infrastructure configuration

This terraform configuration requires multiples variables files for which you can find examples in the repository:

• secrets.tfvars
• ssh_keys.tfvars

You need to copy-paste the examples, remove the .example in the name of the file and fill them up with your real data.

Create the infrastructure

You can create the infrastructure with terraform apply -var-file="secrets.tfvars" -var-file="ssh_keys.tfvars"
