Deprecated

As of July, 2023 this module is deprecated. terraform-aws-s3-website offers little value beyond the terraform-aws-s3-bucket module, so Cloud Posse is phasing out support for this project. Users are advised to migrate to terraform-aws-s3-bucket to manage the S3 bucket (including logging) and terraform-aws-route53-alias to register the website hostname in Route53. Feature requests should be directed to those modules.

Terraform module to provision S3-backed Websites. IMPORTANT: This module provisions a globally accessible S3 bucket for unauthenticated users because it is designed for hosting public static websites. Normally, AWS recommends that S3 buckets should not publicly accessible in order to protect S3 data from unauthorized users.

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

Create s3 website bucket

module "website" {
  source = "cloudposse/s3-website/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  namespace = "eg"
  stage     = "prod"
  name      = "app"
  hostname  = "docs.prod.cloudposse.org"

  deployment_arns = {
    "arn:aws:s3:::principal1" = ["/prefix1", "/prefix2"]
    "arn:aws:s3:::principal2" = [""]
  }
}

Create S3 website bucket with Route53 DNS

Required one of the parent_zone_id or parent_zone_name

module "website_with_cname" {
  source = "cloudposse/s3-website/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  namespace      = "eg"
  stage          = "prod"
  name           = "app"
  hostname       = "docs.prod.cloudposse.org"
  parent_zone_id = "XXXXXXXXXXXX"
}

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
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
allow_ssl_requests_only	Set to true to require requests to use Secure Socket Layer (HTTPS/SSL). This will explicitly deny access to HTTP requests	bool	false	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

cors_allowed_origins	List of allowed origins (e.g. example.com, test.com)	list(string)	[ "*" ]	no
cors_expose_headers	List of expose header in the response	list(string)	[ "ETag" ]	no
cors_max_age_seconds	Time in seconds that browser can cache the response	number	3600	no
delimiter	Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all.	string	null	no
deployment_actions	List of actions to permit deployment ARNs to perform	list(string)	[ "s3:PutObject", "s3:PutObjectAcl", "s3:GetObject", "s3:DeleteObject", "s3:ListBucket", "s3:ListBucketMultipartUploads", "s3:GetBucketLocation", "s3:AbortMultipartUpload" ]	no
deployment_arns	(Optional) Map of deployment ARNs to lists of S3 path prefixes to grant deployment_actions permissions	map(any)	{}	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
encryption_enabled	When set to 'true' the resource will have AES256 encryption enabled by default	bool	false	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.
