Cloudflare

This Driver generates a new subdomain for a domain that is managed in a Cloudflare Zone.

Property Description
Resource type dns
Account type cloudflare

Inputs

Values

Name Type Description
zone_id string The ID of the Cloudflare zone the record is in.
domain string The domain under which to specify the subdomain. For example, staging.example.com
proxied boolean [Optional] A boolean value specifying whether Cloudflare proxies this subdomain. Defaults to false.
ttl integer [Optional] An integer number of seconds that the DNS name should live for. Defaults to 1 which means “Default” in Cloudflare.

Secrets

None

Notes

This Driver adds records to a Cloudflare Zonefile pointing at the Load Balancer for the relevant cluster. The Driver will generate new unique subdomains.

This Driver can be used with environments running on different clusters.

Zone Identifier

Cloudflare organizes resources into “Zones”. You can find the Zone Identifier on the main dash page for the domain. It is at the bottom right under the heading Zone ID.

API Token

The Driver uses a Cloudflare API Token to add, update and remove DNS records. The token must have Zone.DNS edit permissions on the zone the subdomain should be set up in.

The token should be added as an account of type cloudflare.

Example

Use the humanitec/dns-cloudflare Driver to provision a new subdomain under staging.cf-hosted-domain.com for an app called cloudflare-dns-example-app.

First, the Cloud Account containing the Cloudflare API Token must be created:

curl https://api.humanitec.io/orgs/my-org/resources/accounts \
  -X POST \
  -H "Authorization: Bearer ${HUMANITEC_TOKEN}" \
  -H "Content-Type: application/json" \
  --data-binary '{
    "id": "cloudflare-example-account",
    "name": "Cloudflare Example Account",
    "type": "cloudflare",
    "credentials": {
      "token": "kji2b0masdlkfjbaslf-b28n"
    }
  }'

Testing the account will verify that the token is valid, has not expired, and is in the correct form for the Platform Orchestrator to use:

humctl api POST /orgs/my-org/resources/accounts/cloudflare-example-account/actions/check -d '{}'

Then the following dynamic Resource Definition should be added. Apply the following modifications as needed:

  • Adjust the criteria to the Matching Criteria to fit your setup.
  • Decide whether you need to co-provision an ingress resource as shown, and remove the provision section if not. See Routes for a discussion on how the networking Resource Types work together.

Use this Resource Definition for the Humanitec Terraform Provider :

resource "humanitec_resource_definition" "dns-cloudflare" {
  id             = "dynamic-dns-cloudflare"
  name           = "Dynamic DNS via Cloudflare"
  type           = "dns"
  driver_account = "cloudflare-example-account"
  driver_type    = "humanitec/dns-cloudflare"

  driver_inputs = {
    values_string = jsonencode({
      "zone_id" = "1ef520391d97ed73c38bc35dd8b570d0"
      "domain"  = "staging.cf-hosted-domain.com"
      "ttl"     = 1
      "proxied" = false
    })
  }

  provision = {
    ingress = {
      is_dependent = false
    }
  }
}

resource "humanitec_resource_definition_criteria" "dns-cloudflare" {
  resource_definition_id = humanitec_resource_definition.dns-cloudflare.id
  app_id                 = "cloudflare-dns-example-app"
}
