<!-- WARNING: this file is generated -->

This is a terraform module that provisions a
[Spoke](https://github.com/MoveOnOrg/Spoke) instance at DigitalOcean.

## Terraform versions

This module is compatible with Terraform version `0.12+`.

## Usage

A typical production deployment that uses `PASSPORT_STRATEGY=auth0`,
`DEFAULT_SERVICE=twilio`, and a direct SMTP connection for email might look
like this:

```hcl
module "digitalocean_spoke" {
  source = "github.com/meatballhat/tf_digitalocean_spoke"

  server_name      = "spoke.example.org"
  base_url         = "https://spoke.example.org"
  resource_prefix  = "example-spoke-"
  region           = "nyc1"
  ssh_keys         = [file("path/to/id_rsa.pub")]
  cert_private_key = file("path/to/cert.key")
  cert_certificate = file("path/to/cert.crt")
  env = {
    AUTH0_CLIENT_ID            = "8570285697946a0cc03f8049b9309d7e"
    AUTH0_CLIENT_SECRET        = "1194435d32479ef99ed51a0a5f244cd5"
    AUTH0_DOMAIN               = "example.auth0.com"
    EMAIL_FROM                 = "admin@example.org"
    EMAIL_HOST                 = "mail.example.org"
    EMAIL_HOST_PASSWORD        = "b5090d80c82e608a1acd2f59ac366083"
    EMAIL_HOST_PORT            = "123"
    EMAIL_HOST_SECURE          = "true"
    EMAIL_HOST_USER            = "admin"
    DEFAULT_SERVICE            = "twilio",
    PASSPORT_STRATEGY          = "auth0",
    PHONE_NUMBER_COUNTRY       = "US",
    SUPPRESS_SELF_INVITE       = "true",
    TWILIO_API_KEY             = "6babd5fa8226c66406edcce7390675b3"
    TWILIO_APPLICATION_SID     = "be2d8e141ab5b45287d06ee649c48b82"
    TWILIO_AUTH_TOKEN          = "17381f485e35f89608b88b45f5a00873"
    TWILIO_MESSAGE_SERVICE_SID = "b2b551ca3228aa8d130b5739e1a20cdd"
    TWILIO_STATUS_CALLBACK_URL = "https://callback.example.org"
  }
