Simple Terraform configuration to setup CloudFlare DNS using S3 as Backend

tf-cloudflare

Simple Terraform configuration to create the following resources:

• CloudFlare DNS Zone;
• CloudFlare DNS Records;
• AWS S3 bucket (to store TF state);
• AWS S3 acl (to keep the bucket private);
• AWS S3 Versioning (speaks for itself right?);
• AWS DynamoDB (to prevent write operations while another is already ongoing);

Prerequisites:

• CloudFlare account (free plan will do);
• AWS account: -> S3 (to store just the tf state file, S3 will cost less than 1 cent a month); -> DynamoDB (AWS offers 25GB of storage FOREVER);

To generate your CloudFlare API Key access, if you don't already have one: https://dash.cloudflare.com/profile/api-tokens

How to use:

1. Setup tf variables, if you are running this locally i recommend to create a terraform.tfvars and put this:

domain                  = "<your-domain>"
cloudflare_email        = "<your-cloudflare-email-account>"
cloudflare_api_key      = "<your-cloudflare-generated-api-key>"

2. Assuming that you have already configured your AWS access credentials, Initialize Terraform to start downloading Providers (CloudFlare and AWS) and Setup S3 and DynamoDB as Backend:

$ terraform init

3. Plan and Appply your code:

$ terraform plan && terraform apply --auto-approve

4. See the resources created:

$ terraform show

5. Destroy all resources created previously:

$ terraform destroy --auto-approve
