terraform-aws-website-secure

Creates a private website behind a cloudfront distribution, with SSL enabled. Custom Cognito hosted UI is put in front of it.

The website files are hosted in an S3 bucket which is also created by the module.

Usage

module "website" {
    source = "timmeinerzhagen/website-secure/aws"
    
    name           = "tf-my-project"
    domain         = "example.com"
    custom_domain  = "example.com"
    domain_aliases = ["www.example.com"]
    is_spa         = false
    csp            = {
        allow_default = ["api.mysite.com"]
        allow_style = ["'unsafe-inline'"]
        allow_img = ["data:"]
        allow_font = []
        allow_frame = []
        allow_manifest = []
        allow_connect = []
    }

    cloudfront_cache_duration = 86400

    cognito_path_refresh_auth       = "/refreshauth"
    cognito_path_logout             = "/"
    cognito_path_parse_auth         = "/parseauth"
    cognito_refresh_token_validity  = 3650
    cognito_additional_redirects    = ["http:https://localhost:3000"]  // Useful for development purposes

Inputs

Name Description Type Default Required
cognito_additional_redirects Additional URLs to allow cognito redirects to list(string) [] no
cognito_domain_prefix The first part of the hosted UI login domain, as in https://[COGNITO_DOMAIN_PREFIX].[CUSTOM_DOMAIN]/ string "login" no

cognito_refresh_token_validity Time until the refresh token expires and the user will be required to log in again number 3650 no
content_html_rewrite Boolean, default false. If true, any URL where the final part does not contain a . will reference the S3 object with html appended. For example https://example.com/home would retrieve the file home.html from the website S3 bucket. bool false no
