Amazon S3

The Amazon S3 screen enables you to configure settings for integrating Amazon S3 into your website.

Accessing the screen

Under "SETTINGS", click [External system integration] -> [Amazon S3].

Field descriptions

Field	Description
Bucket	Enter the S3 bucket name.
AWS access key	Enter the Access key ID from AWS.
Secret access key	Enter the Secret access key from AWS.
IAM role ARN for AssumeRole	Enter the ARN of the AWS IAM role to assume. Configure this when using container credentials (e.g., ECS) instead of an access key and secret access key.
Disable S3 ACL	When enabled, the ACL parameter is omitted from S3 file upload and copy operations. Enable this when the S3 bucket has Object Ownership set to "Bucket owner enforced" (ACLs disabled).
CORS auto-update	When disabled, Kuroco stops automatically updating the S3 CORS configuration, allowing you to manage CORS settings directly on the AWS side. Enabled by default.
Additional CORS origins	Enter a domain to allow viewing and retrieving files on S3 from that domain.
Bucket Policy	Displayed when both [Disable S3 ACL] and [CORS auto-update] are enabled and a bucket is configured. Shows the JSON of the bucket policy that is automatically applied to maintain read access to the public prefix (files/a/public/).
Update	Click to apply the changes you made on this screen.
