OriginAccessIdentity

class OriginAccessIdentity : KotlinCustomResource

Creates an Amazon CloudFront origin access identity. For information about CloudFront distributions, see the Amazon CloudFront Developer Guide. For more information on generating origin access identities, see Using an Origin Access Identity to Restrict Access to Your Amazon S3 Content.

Example Usage

The following example below creates a CloudFront origin access identity.

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
const example = new aws.cloudfront.OriginAccessIdentity("example", {comment: "Some comment"});

import pulumi
import pulumi_aws as aws
example = aws.cloudfront.OriginAccessIdentity("example", comment="Some comment")

using System.Collections.Generic;
using System.Linq;
using Pulumi;
using Aws = Pulumi.Aws;
return await Deployment.RunAsync(() =>
{
    var example = new Aws.CloudFront.OriginAccessIdentity("example", new()
    {
        Comment = "Some comment",
    });
});

package main
import (
	"github.com/pulumi/pulumi-aws/sdk/v6/go/aws/cloudfront"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)
func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := cloudfront.NewOriginAccessIdentity(ctx, "example", &cloudfront.OriginAccessIdentityArgs{
			Comment: pulumi.String("Some comment"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

Using With CloudFront

Normally, when referencing an origin access identity in CloudFront, you need to prefix the ID with the origin-access-identity/cloudfront/ special path. The cloudfront_access_identity_path allows this to be circumvented. The below snippet demonstrates use with the s3_origin_config structure for the aws.cloudfront.Distribution resource:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
const example = new aws.cloudfront.Distribution("example", {origins: [{
    s3OriginConfig: {
        originAccessIdentity: exampleAwsCloudfrontOriginAccessIdentity.cloudfrontAccessIdentityPath,
    },
}]});

import pulumi
import pulumi_aws as aws
example = aws.cloudfront.Distribution("example", origins=[{
    "s3_origin_config": {
        "origin_access_identity": example_aws_cloudfront_origin_access_identity["cloudfrontAccessIdentityPath"],
    },
}])

using System.Collections.Generic;
using System.Linq;
using Pulumi;
using Aws = Pulumi.Aws;
return await Deployment.RunAsync(() =>
{
    var example = new Aws.CloudFront.Distribution("example", new()
    {
        Origins = new[]
        {
            new Aws.CloudFront.Inputs.DistributionOriginArgs
            {
                S3OriginConfig = new Aws.CloudFront.Inputs.DistributionOriginS3OriginConfigArgs
                {
                    OriginAccessIdentity = exampleAwsCloudfrontOriginAccessIdentity.CloudfrontAccessIdentityPath,
                },
            },
        },
    });
});

package main
import (
	"github.com/pulumi/pulumi-aws/sdk/v6/go/aws/cloudfront"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)
func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := cloudfront.NewDistribution(ctx, "example", &cloudfront.DistributionArgs{
			Origins: cloudfront.DistributionOriginArray{
				&cloudfront.DistributionOriginArgs{
					S3OriginConfig: &cloudfront.DistributionOriginS3OriginConfigArgs{
						OriginAccessIdentity: pulumi.Any(exampleAwsCloudfrontOriginAccessIdentity.CloudfrontAccessIdentityPath),
					},
				},
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

Updating your bucket policy

Note that the AWS API may translate the s3_canonical_user_id CanonicalUser principal into an AWS IAM ARN principal when supplied in an aws.s3.BucketV2 bucket policy, causing spurious diffs. If you see this behavior, use the iam_arn instead:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
const s3Policy = aws.iam.getPolicyDocument({
    statements: [{
        actions: ["s3:GetObject"],
        resources: [`${exampleAwsS3Bucket&#46;arn}/*`],
        principals: [{
            type: "AWS",
            identifiers: [exampleAwsCloudfrontOriginAccessIdentity&#46;iamArn],
        }],
    }],
});
const example = new aws.s3.BucketPolicy("example", {
    bucket: exampleAwsS3Bucket.id,
    policy: s3Policy.then(s3Policy => s3Policy.json),
});

import pulumi
import pulumi_aws as aws
s3_policy = aws.iam.get_policy_document(statements=[{
    "actions": ["s3:GetObject"],
    "resources": [f"{example_aws_s3_bucket['arn']}/*"],
    "principals": [{
        "type": "AWS",
        "identifiers": [example_aws_cloudfront_origin_access_identity["iamArn"]],
    }],
}])
example = aws.s3.BucketPolicy("example",
    bucket=example_aws_s3_bucket["id"],
    policy=s3_policy.json)

using System.Collections.Generic;
using System.Linq;
using Pulumi;

return await Deployment.RunAsync(() =>

        {

            {

                {
                    "s3:GetObject",
                },
                Resources = new[]
                {
