Using Terraform
===============
This is a `Terraform <https://www.terraform.io/>`__ configuration that sets up DigitalOcean droplets.
Prerequisites
-------------
- Install `HashiCorp Terraform <https://www.terraform.io>`__ on a linux machine.
- Create a `DigitalOcean API token <https://cloud.digitalocean.com/settings/api/tokens>`__ with read and write capability.
- Create SSH keys
Build
-----
::
export DO_API_TOKEN="abcdef01234567890abcdef01234567890"
export TESTNET_NAME="remotenet"
export SSH_PUBLIC_FILE="$HOME/.ssh/id_rsa.pub"
export SSH_PRIVATE_FILE="$HOME/.ssh/id_rsa"
terraform init
terraform apply -var DO_API_TOKEN="$DO_API_TOKEN" -var SSH_PUBLIC_FILE="$SSH_PUBLIC_FILE" -var SSH_PRIVATE_FILE="$SSH_PRIVATE_FILE"
At the end you will get a list of IP addresses that belongs to your new droplets.
Destroy
-------
Run the below:
::
terraform destroy -var DO_API_TOKEN="$DO_API_TOKEN" -var SSH_PUBLIC_FILE="$SSH_PUBLIC_FILE" -var SSH_PRIVATE_FILE="$SSH_PRIVATE_FILE"
Good to know
------------
The DigitalOcean API was not very reliable for me. If you find that terraform fails to install a specific server (for example cluster[2]), check
the regions variable and remove data center names that you find unreliable. The variable is at cluster/variables.tf
Example:
::
variable "regions" {
description = "Regions to launch in"
type = "list"
default = ["TOR1", "LON1"]
}
