Terraform module to provision a CloudFlare zone with: DNS records, Argo, Firewall filters and rules.

Tip

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.

Watch demo of using Atmos with Terraform

Example of running atmos to manage infrastructure from our Quick Start tutorial.

Usage

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest (which tests and deploys the example on AWS), see test.

module "label" {
  source = "cloudposse/label/null"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  namespace  = "eg"
  stage      = "prod"
  name       = "cf"
  delimiter  = "-"
}

module "zone" {
  source = "cloudposse/zone/cloudflare"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"

  account_id = "example-account-id"
  zone       = "cloudposse.co"
  records    = [
    {
      name  = "bastion"
      value = "192.168.1.11"
      type  = "A"
      ttl   = 3600
    },
    {
      name  = "api"
      value = "192.168.2.22"
      type  = "A"
      ttl   = 3600
    }
  ]

  context = module.label.context
}

Important

In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Inputs

Name	Description	Type	Default	Required
account_id	Cloudflare account ID to manage the zone resource in	string	n/a	yes
additional_tag_map	Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id. This is for some rare cases where resources want additional configuration of tags and therefore take a list of maps with tag key, value, and additional configuration.	map(string)	{}	no
argo_enabled	Whether to enable Cloudflare Argo for DNS zone	bool	false	no
argo_smart_routing_enabled	Whether smart routing is enabled.	bool	true	no
argo_tiered_caching_enabled	Whether tiered caching is enabled.	bool	true	no
attributes	ID element. Additional attributes (e.g. workers or cluster) to add to id, in the order they appear in the list. New attributes are appended to the end of the list. The elements of the list are joined by the delimiter and treated as a single ID element.	list(string)	[]	no
context	Single object for setting entire context at once. See description of individual variables for details. Leave string and numeric variables as null to use default value. Individual variable settings (non-null) override settings in context object, except for attributes, tags, and additional_tag_map, which are merged.	any	{ "additional_tag_map": {}, "attributes": [], "delimiter": null, "descriptor_formats": {}, "enabled": true, "environment": null, "id_length_limit": null, "label_key_case": null, "label_order": [], "label_value_case": null, "labels_as_tags": [ "unset" ], "name": null, "namespace": null, "regex_replace_chars": null, "stage": null, "tags": {}, "tenant": null }	no
delimiter	Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all.	string	null	no
descriptor_formats	Describe additional descriptors to be output in the descriptors output map. Map of maps. Keys are names of descriptors. Values are maps of the form {<br/> format = string<br/> labels = list(string)<br/>} (Type is any so the map values can later be enhanced to provide additional options.) format is a Terraform format string to be passed to the format() function. labels is a list of labels, in order, to pass to format() function. Label values will be normalized before being passed to format() so they will be identical to how they appear in id. Default is {} (descriptors output will be empty).	any	{}	no
enabled	Set to false to prevent the module from creating any resources	bool	null	no
environment	ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'	string	null	no
healthchecks	A list of maps of Health Checks rules. The values of map is fully compliant with cloudflare_healthcheck resource. To get more info see https://registry.terraform.io/providers/cloudflare/cloudflare/latest/docs/resources/healthcheck	list(any)	null	no
id_length_limit	Limit id to this many characters (minimum 6). Set to 0 for unlimited length. Set to null for keep the existing setting, which defaults to 0. Does not affect id_full.	number	null	no
jump_start	Whether to scan for DNS records on creation.	bool	false	no
label_key_case	Controls the letter case of the tags keys (label names) for tags generated by this module. Does not affect keys of tags passed in via the tags input. Possible values: lower, title, upper. Default value: title.	string	null	no
label_order	The order in which the labels (ID elements) appear in the id. Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.	list(string)	null	no
label_value_case	Controls the letter case of ID elements (labels) as included in id, set as tag values, and output by this module individually. Does not affect values of tags passed in via the tags input. Possible values: lower, title, upper and none (no transformation). Set this to title and set delimiter to "" to yield Pascal Case IDs. Default value: lower.	string	null	no
labels_as_tags	Set of labels (ID elements) to include as tags in the tags output. Default is to include all labels. Tags with empty values will not be included in the tags output. Set to [] to suppress all generated tags. Notes: The value of the name tag, if included, will be the id, not the name. Unlike other null-label inputs, the initial setting of labels_as_tags cannot be changed in later chained modules. Attempts to change it will be silently ignored.	set(string)	[ "default" ]	no
name	ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'. This is the only ID element not also included as a tag. The "name" tag is set to the full id string. There is no tag with the value of the name input.	string	null	no
namespace	ID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally unique	string	null	no
page_rules	A list of maps of Page Rules. The values of map is fully compliant with cloudflare_page_rule resource. To get more info see https://registry.terraform.io/providers/cloudflare/cloudflare/latest/docs/resources/cloudflare_page_rule	list(any)	null	no

plan	The name of the commercial plan to apply to the zone. Possible values: free, pro, business, enterprise	string	"free"	no
records	name: The name of the record. type: The type of the record. value: The value of the record. comment: Optional comment for the record. ttl: The TTL of the record. Default value: 1. priority: The priority of the record. proxied: Whether the record gets Cloudflare's origin protection. Default value: false.	list(any)	[]	no
regex_replace_chars	Terraform regular expression (regex) string. Characters matching the regex will be removed from the ID elements. If not set, "/[^a-zA-Z0-9-]/" is used to remove all characters other than hyphens, letters and digits.	string	null	no
stage	ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'	string	null	no
tags	Additional tags (e.g. {'BusinessUnit': 'XYZ'}). Neither the tag keys nor the tag values will be modified by this module.	map(string)	{}	no
tenant	ID element _(Rarely used, not included by default)_. A customer identifier, indicating who this instance of a resource is for	string	null	no
type	A full zone implies that DNS is hosted with Cloudflare. A partial zone is typically a partner-hosted zone or a CNAME setup. Possible values: full, partial.	string	"full"	no
