Always free Wireguard VPN server

Free VPN

Create an always free WireGuard VPN server on Oracle Cloud using Terraform and Ansible.

Prerequisites

• Install the following packages:
  • terraform
  • ansible
• Create a Terraform backend (I'm using Terraform Cloud)
• Create an Oracle Cloud account
• Generate an API signing key:
  • Profile menu (User menu icon) -> User Settings -> API Keys -> Add API Key
  • Select Generate API Key Pair, download the private key and click Add
  • Check the Configuration File Preview for the values

Put those values in ./infra/terraform.tfvars:

user_id = "ocid1.user.xxx"
fingerprint = "xx:xx:xx"
tenancy_id = "ocid1.tenancy.xxx"
region = "us-xxx"
private_key = <<EOT
-----BEGIN PRIVATE KEY-----
xxx (from the downloaded private key)
-----END PRIVATE KEY-----
EOT

Get started

Provision

Change your backend config in ./infra/versions.tf (or you can remove that block and use local backend), then run:
