S3 Bucket

resource "aws_s3_bucket" "s3_origin" { bucket = "sampleawsccbucket345" }

Block public access to S3 bucket

Attach bucket policy with object access to cloudfront origin

Cloudfront origin access identity

IAM policy document to allow S3 bucket read access to cloudfront origin access identity

Debug Output

Terraform resources getting created without errors.

Panic Output

Expected Behavior

Origin access settings on the cloudfront distribution should have used the Origin Access Identity (OAI) option selected with the OAI resource which was created part of the terraform resource configuration

Actual Behavior

Origin access settings on the cloudfront distribution uses the default setting [i.e., expects S3 public access] and did not use the OAI option using the OAI resource which was created.

Steps to Reproduce

1. terraform apply

After 1st time terraform apply, resources are created successfully but terraform state has missing resource. When trying to perform terraform plan/apply again the 2nd time, it shows changes to the plan and resources when trying to apply the changes getting the below error

Error: AWS SDK Go Service Operation Incomplete │ │ with awscc_cloudfront_distribution.cloudfront_s3_origin, │ on cloudfront-with-s3-origin-oac.tf line 55, in resource "awscc_cloudfront_distribution" "cloudfront_s3_origin": │ 55: resource "awscc_cloudfront_distribution" "cloudfront_s3_origin" { │ │ Waiting for Cloud Control API service UpdateResource operation completion returned: waiter state transitioned to FAILED.

When I use CCAPI to describe the resource, I got different value returned, for example the DefaultCacheBehavior:

note: formatted for readability

"DefaultCacheBehavior": {
  . . .
  "TargetOriginId": "Default",
  "ViewerProtocolPolicy": "allow-all",
  . . .
  "DefaultTTL": 86400,
   . . .
  "AllowedMethods": [
    "HEAD",
    "GET"
  ],
  "CachedMethods": [
    "HEAD",
    "GET"
  ],
  . . .
  "MinTTL": 0,
  "MaxTTL": 31536000
},

as oppose to the HCL configuration:

    default_cache_behavior = {
      target_origin_id       = aws_s3_bucket.s3_origin.id
      viewer_protocol_policy = "redirect-to-https"
      allowed_methods        = ["GET", "HEAD", "OPTIONS"]
      cached_methods         = ["GET", "HEAD", "OPTIONS"]
      min_ttl                = 0
      default_ttl            = 5 * 60
      max_ttl                = 60 * 60
    }

and Terraform state

"default_cache_behavior": {
  "allowed_methods": [
    "GET",
    "HEAD",
    "OPTIONS"
  ],
  "cache_policy_id": null,
  "cached_methods": [
    "GET",
    "HEAD",
    "OPTIONS"
  ],
  . . .
  "default_ttl": 300,
  . . .
  "max_ttl": 3600,
  "min_ttl": 0,
  . . . 
  "target_origin_id": "terraform-20230720041249283400000001",
  . . .
  "viewer_protocol_policy": "redirect-to-https"
},

Even forgoing CC this looks strange.

resource "awscc_cloudfront_distribution" "this" {
  distribution_config = {
    enabled = false

    default_cache_behavior = {
      target_origin_id       = "example.com"
      viewer_protocol_policy = "redirect-to-https"

      forwarded_values = {
        query_string = false
      }
    }
    viewer_certificate = {
      cloudfront_default_certificate = true
      minimum_protocol_version       = "TLSv1.2_2018"
    }

    origins = [{
      domain_name = "example.com"
      id          = "example.com"
      custom_origin_config = {
        origin_protocol_policy = "https-only"
      }
    }]
  }
}

corresponds to a CreateDistribution call with the intended minimumProtocolVersion
