Cloudflare Terraforming
Overview
cf-terraforming is a command line utility to facilitate terraforming your existing Cloudflare resources. It does this by using your account credentials to retrieve your configurations from the Cloudflare API and converting them to Terraform configurations that can be used with the Terraform Cloudflare provider.
This tool is ideal if you already have Cloudflare resources defined but want to start managing them via Terraform, and don't want to spend the time to manually write the Terraform configuration to describe them.

Use "cf-terraforming [command] --help" for more information about a command.
Example
A note on storing your credentials securely: We recommend that you store your Cloudflare credentials (API key, email, account ID, etc) as environment variables as demonstrated below.
You can use go run to build and execute the binary in a single command like so:
go run cmd/cf-terraforming/main.go --email $CLOUDFLARE_EMAIL --key $CLOUDFLARE_TOKEN --account $CLOUDFLARE_ACCOUNT_ID spectrum_application
will contact the Cloudflare API on your behalf and result in a valid Terraform configuration representing the resource you requested:
resource "cloudflare_spectrum_application" "1150bed3f45247b99f7db9696fffa17cbx9" {
protocol = "tcp/8000"
dns = {
type = "CNAME"
name = "example.com"
}
ip_firewall = "true"
tls = "off"
origin_direct = [ "tcp://37.241.37.138:8000", ]
}
See the currently supported resources below.
Download all Cloudflare resources
Use the all command to download everything and convert it into Terraform config.
go run cmd/cf-terraforming/main.go --email $CLOUDFLARE_EMAIL --key $CLOUDFLARE_TOKEN --account $CLOUDFLARE_ACCOUNT_ID all
Controlling output and verbose mode
By default, cf-terraforming will not output any log type messages to stdout when run, so as to not pollute your generated Terraform config files and to allow you to cleanly redirect cf-terraforming output to existing Terraform configs.
However, it can be useful when debugging issues to specify a logging level, like so:
go run cmd/cf-terraforming/main.go --email $CLOUDFLARE_EMAIL --key $CLOUDFLARE_TOKEN -a 1233455678d876bc764b5f763af7644411 -l="debug" spectrum_application

For convenience, you can set the verbose flag, which is functionally equivalent to setting a log level of debug:
go run cmd/cf-terraforming/main.go --email $CLOUDFLARE_EMAIL --key $CLOUDFLARE_TOKEN -a 1233455678d876bc764b5f763af7644411 -v spectrum_application
Prerequisites
- A Cloudflare account with resources defined (e.g. a few zones, some load balancers, spectrum applications, etc)
- A valid Cloudflare API key and sufficient permissions to access the resources you are requesting via the API
- A working installation of Go
Installation
$ go get -u github.com/cloudflare/cf-terraforming/...This will fetch the cf-terraforming tool as well as its dependencies, updating them as necessary.
Experimental: exporting tfstate
Work is underway to support downloading your resources via cf-terraform as valid tfstate, which will allow you to skip importing and let Terraform become aware of and begin managing your resources immediately.
Currently, only the worker_route command supports the --tfstate flag, but support for downloading tfstate will steadily be added across the other resources supported by cf-terraforming.
To use this currently experimental feature, pass the --tfstate (-s) flag to your command like so:
$ go run cmd/cf-terraforming/main.go --email $CLOUDFLARE_EMAIL --key $CLOUDFLARE_API_KEY -z example.com -a $CLOUDFLARE_ACCOUNT_ID --organization $CLOUDFLARE_ORG_ID --tfstate worker_route
The output will look something like this:
{
"version": 1,
"terraform_version": "",
"serial": 0,
"lineage": "",
"modules": [
{
"path": ["root"],
"depends_on": [],

},

}
}
}]
}
This means that when you next run $ terraform plan, Terraform should see no difference between your defined resources and your current tfstate.
