spa-s3-cloudfront

This component provisions infrastructure to serve a Single Page Application (SPA) via Amazon S3 and Amazon CloudFront.

S3 bucket to host SPA assets
CloudFront distribution for global CDN delivery
ACM certificate issued in us-east-1 (required by CloudFront)

NOTE: The component does not use the ACM created by dns-delegated, because the ACM region has to be us-east-1.

Usage

Stack Level: Regional

Here are some example snippets for how to use this component:

An import for all instantiations of the spa-s3-cloudfront component can be created at stacks/spa/spa-defaults.yaml:

components:
  terraform:
    spa-s3-cloudfront:
      vars:
        # lookup GitHub Runner IAM role via remote state
        github_runners_deployment_principal_arn_enabled: true
        github_runners_component_name: github-runners
        github_runners_tenant_name: core
        github_runners_environment_name: ue2
        github_runners_stage_name: auto
        origin_force_destroy: false
        origin_versioning_enabled: true
        origin_block_public_acls: true
        origin_block_public_policy: true
        origin_ignore_public_acls: true
        origin_restrict_public_buckets: true
        origin_encryption_enabled: true
        cloudfront_index_document: index.html
        cloudfront_ipv6_enabled: false
        cloudfront_compress: true
        cloudfront_default_root_object: index.html
        cloudfront_viewer_protocol_policy: redirect-to-https

An import for all instantiations for a specific SPA can be created at stacks/spa/example-spa.yaml:

components:
  terraform:
    example-spa:
      component: spa-s3-cloudfront
      vars:
        name: example-spa
        site_subdomain: example-spa
        cloudfront_allowed_methods:
          - GET
          - HEAD
        cloudfront_cached_methods:
          - GET
          - HEAD
        cloudfront_custom_error_response:
          - error_caching_min_ttl: 1
            error_code: 403
            response_code: 200
            response_page_path: /index.html
        cloudfront_default_ttl: 60
        cloudfront_min_ttl: 60
        cloudfront_max_ttl: 60

Finally, the spa-s3-cloudfront component can be instantiated in a stack config:

import:
  - spa/example-spa

components:
  terraform:
    example-spa:
      component: spa-s3-cloudfront
      settings:
        spacelift:
          workspace_enabled: true
      vars: {}

Failover Origins

Failover origins are supported via var.failover_s3_origin_name and var.failover_s3_origin_region.

Preview Environments

SPA Preview environments (i.e. subdomain.example.com mapping to a /subdomain path in the S3 bucket) powered by Lambda@Edge are supported via var.preview_environment_enabled. See the both the variable description and inline documentation for an extensive explanation for how these preview environments work.

Customizing Lambda@Edge

This component supports customizing Lambda@Edge functions for the CloudFront distribution. All Lambda@Edge function configuration is deep merged before being passed to the cloudposse/cloudfront-s3-cdn/aws//modules/lambda@edge module. You can add additional functions and overwrite existing functions as such:

import:
  - catalog/spa-s3-cloudfront/defaults

components:
  terraform:
    refarch-docs-site-spa:
      metadata:
        component: spa-s3-cloudfront
        inherits:
          - spa-s3-cloudfront-defaults
      vars:
        enabled: true
        lambda_edge_functions:
          viewer_request: # overwrite existing function
            source: null # this overwrites the 404 viewer request source with deep merging
            source_zip: "./dist/lambda_edge_paywall_viewer_request.zip"
            runtime: "nodejs16.x"
            handler: "index.handler"
            event_type: "viewer-request"
            include_body: false
          viewer_response: # new function
            source_zip: "./dist/lambda_edge_paywall_viewer_response.zip"
            runtime: "nodejs16.x"
            handler: "index.handler"
            event_type: "viewer-response"
            include_body: false

failover S3 origin exists. Setting this variable will enable use of a failover S3 origin, but it is required for the
failover S3 origin to exist beforehand. This variable is used in conjunction with var.failover_s3_origin_format to
build out the name of the Failover S3 origin in the specified region.

For example, if this component creates an origin of name eg-ue1-devplatform-example and this variable is set to uw1,
then it is expected that a bucket with the name eg-uw1-devplatform-example-failover exists in us-west-1.

Default value: null

building the name via format([format], var.namespace, var.failover_s3_origin_environment, var.stage, var.name)
and then looking it up via the aws_s3_bucket Data Source.

For example, if this component creates an origin of name eg-ue1-devplatform-example and var.failover_s3_origin_environment
is set to uw1, then it is expected that a bucket with the name eg-uw1-devplatform-example-failover exists in us-west-1.

Default value: [ ]

lambda_edge_destruction_delay (string) optional

The delay, in Golang ParseDuration format, to wait before destroying the Lambda@Edge
functions.

This delay is meant to circumvent Lambda@Edge functions not being immediately deletable following their dissociation from
a CloudFront distribution, since they are replicated to CloudFront Edge servers around the world.

If set to null, no delay will be introduced.

By default, the delay is 20 minutes. This is because it takes about 3 minutes to destroy a CloudFront distribution, and
around 15 minutes until the Lambda@Edge function is available for deletion, in most cases.

If set to true, then the S3 origin access logs bucket name will be rendered by calling format("%v-%v-%v-%v", var.namespace, var.environment, var.stage, var.origin_s3_access_log_bucket_name).
Otherwise, the value for origin_s3_access_log_bucket_name will need to be the globally unique name of the access logs bucket.

For example, if this component produces an origin bucket named eg-ue1-devplatform-example and origin_s3_access_log_bucket_name is set to
example-s3-access-logs, then the bucket name will be rendered to be eg-ue1-devplatform-example-s3-access-logs.

Setting preview_environment_enabled will implicitly set this to true.

Default value: false

s3_website_password_enabled (bool) optional

If set to true, and s3_website_enabled is also true, a password will be required in the Referrer field of the
HTTP request in order to access the website, and CloudFront will be configured to pass this password in its requests.
This will make it much harder for people to bypass CloudFront and access the S3 website directly via its website endpoint.

Default value: false

site_fqdn (string) optional

Fully qualified domain name of site to publish. Overrides site_subdomain and parent_zone_name.

Default value: ""

Set this to title and set delimiter to "" to yield Pascal Case IDs.
Default value: lower.

Required: No

Default value: null

labels_as_tags (set(string)) optional
