Terraform Configuration Files

Please include all Terraform configurations required to reproduce the bug. Bug reports without a functional reproduction may be closed without investigation.

resource "aws_cloudfront_distribution" "site" {
  origin {
    domain_name = var.domain-name
    origin_id   = "${var.origin-id-prefix}-${var.domain-name}"

    custom_origin_config {
      http_port  = 80
      https_port = 443

      origin_protocol_policy   = "https-only"
      origin_keepalive_timeout = 600
      origin_read_timeout      = 31

      origin_ssl_protocols = ["TLSv1.2"] # TLS 1.2 is required for PCI compliance
    }

Debug Output

Error: expected origin.0.custom_origin_config.0.origin_keepalive_timeout to be in the range (1 - 180), got [600]
 
  with module.cdn-site.aws_cloudfront_distribution.site,
  on ../../../modules/cdn/site/site.tf line 33, in resource "aws_cloudfront_distribution" "site":
  33: resource "aws_cloudfront_distribution" "site" {

Expected Behavior

We should be able to allow any value for origin_keepalive_timeout. It's up to AWS to restrict really high values not terraform since you can negotiate with AWS to allow high values in certain cases.

Actual Behavior

Error running terraform plan only allowing a max value of 180.

Steps to Reproduce

Set origin_keepalive_timeout to something higher then 180 seconds.

1. terraform apply
