# Cross Provider Example
|
||
|
|
|
||
|
|
This is a simple example of the cross-provider capabilities of
|
||
|
|
Terraform.
|
||
|
|
|
||
|
|
Very simply, this creates a Heroku application and points a DNS
|
||
|
|
CNAME record at the result via DNSimple. A `host` query to the outputted
|
||
|
|
hostname should reveal the correct DNS configuration.
|
||
|
|
|
||
|
|
## Command
|
||
|
|
|
||
|
|
```
|
||
|
|
terraform apply \
|
||
|
|
-var 'heroku_email=YOUR_EMAIL' \
|
||
|
|
-var 'heroku_api_key=YOUR_KEY' \
|
||
|
|
-var 'dnsimple_domain=example.com' \
|
||
|
|
-var 'dnsimple_email=YOUR_EMAIL' \
|
||
|
|
-var 'dnsimple_token=YOUR_TOKEN'
|
||
|
|
```
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
```
|
||
|
|
variable "heroku_email" {}
|
||
|
|
variable "heroku_api_key" {}
|
||
