AWS v7.1.0 published on Monday, Jul 21, 2025 by Pulumi
pulumi/pulumi-aws

    Provides an S3 bucket CORS configuration resource. For more information about CORS, go to Enabling Cross-Origin Resource Sharing in the Amazon S3 User Guide.

    NOTE: S3 Buckets only support a single CORS configuration. Declaring multiple aws.s3.BucketCorsConfiguration resources to the same S3 Bucket will cause a perpetual difference in configuration.

    This resource cannot be used with S3 directory buckets.

    Example Usage

    import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const example = new aws.s3.Bucket("example", {bucket: "mybucket"});
const exampleBucketCorsConfiguration = new aws.s3.BucketCorsConfiguration("example", {
    bucket: example.id,
    corsRules: [
        {
            allowedHeaders: ["*"],
            allowedMethods: [
                "PUT",
                "POST",
            ],
            allowedOrigins: ["https://s3-website-test.domain.example"],
            exposeHeaders: ["ETag"],
            maxAgeSeconds: 3000,
        },
        {
            allowedMethods: ["GET"],
            allowedOrigins: ["*"],
        },
    ],
});

    import pulumi
import pulumi_aws as aws

example = aws.s3.Bucket("example", bucket="mybucket")
example_bucket_cors_configuration = aws.s3.BucketCorsConfiguration("example",
    bucket=example.id,

    Import

    If the owner (account ID) of the source bucket differs from the account used to configure the AWS Provider, import using the bucket and expected_bucket_owner separated by a comma (,):

    Using pulumi import to import S3 bucket CORS configuration using the bucket or using the bucket and expected_bucket_owner separated by a comma (,). For example:

    If the owner (account ID) of the source bucket is the same account used to configure the AWS Provider, import using the bucket:

    $ pulumi import aws:s3/bucketCorsConfiguration:BucketCorsConfiguration example bucket-name

    If the owner (account ID) of the source bucket differs from the account used to configure the AWS Provider, import using the bucket and expected_bucket_owner separated by a comma (,):

    $ pulumi import aws:s3/bucketCorsConfiguration:BucketCorsConfiguration example bucket-name,123456789012
