To enable access logging in AWS CloudFront distribution set the 'logging_config' field :

resource "aws_cloudfront_distribution" "test" {
	origin {
		domain_name = aws_s3_bucket.b.bucket_regional_domain_name
		origin_id   = local.s3_origin_id
		s3_origin_config {
			origin_access_identity = "origin-access-identity/cloudfront/ABCDEFG1234567"
	enabled             = true
	is_ipv6_enabled     = true
	default_root_object = "index.html"
	+ logging_config {
		+   include_cookies = false
		+   bucket          = "mylogs.s3.amazonaws.com"
		+   prefix          = "myprefix"
	+ }

Amazon CloudFront

Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, for example, .html, .css, .php, image, and media files, to end users. CloudFront delivers your content through a worldwide network of edge locations. When an end user requests content that you're serving with CloudFront, the user is routed to the edge location that provides the lowest latency, so content is delivered with the best possible performance. If the content is already in that edge location, CloudFront delivers it immediately.
