# aws\_cloudfront\_distribution
|
|
|
|
|
|
|
|
Creates an Amazon CloudFront web distribution.
|
|
|
|
|
|
|
|
For information about CloudFront distributions, see the
|
|
|
|
[Amazon CloudFront Developer Guide][1]. For specific information about creating
|
|
|
|
CloudFront web distributions, see the [POST Distribution][2] page in the Amazon
|
|
|
|
CloudFront API Reference.
|
|
|
|
|
|
|
|
~> **NOTE:** CloudFront distributions take about 15 minutes to a deployed state
|
|
|
|
after creation or modification. During this time, deletes to resources will be
|
|
|
|
blocked. If you need to delete a distribution that is enabled and you do not
|
|
|
|
want to wait, you need to use the `retain_on_delete` flag.
|
|
|
|
|
|
|
|
## Example Usage
|
|
|
|
|
|
|
|
The following example below creates a CloudFront distribution with an S3 origin.
|
|
|
|
|
|
|
|
```
|
|
|
|
resource "aws_cloudfront_distribution" "s3_distribution" {
