Update your access endpoint with a custom URL - AWS Transfer Family

Update your access endpoint with a custom URL

The default access endpoint that is created with your web app contains service-generated identifiers. To provide a branded experience, you may want to provide a custom URL for your users to access your Transfer Family web app. This topic describes how to update your access endpoint with a custom URL.

Note

The following procedure relies on you using the recommended CloudFormation stack template. You don't need to use the template: you can create the distribution by using the CloudFront console directly.

However, the provided template simplifies the process, and makes it easier to avoid misconfiguration. If you don't use the AWS CloudFormation template, make sure to follow these guidelines:

  • The Origin request policy should forward query strings and cookies to the origin, and should not forward the Host header to the origin.

  • The Cache policy should not include the Host header in the cache key.

  • The Min TTL should not be greater than zero (0).

To customize your web app URL

  1. Create a CloudFront distribution by using the Transfer Family supplied AWS CloudFormation template, CloudFormation stack template.

    1. Open the AWS CloudFormation console at https://console.aws.amazon.com/cloudformation.

    2. Choose Create stack and specify the following.

      • In the Prerequisite - Prepare template section, choose Choose an existing template.

      • In the Specify template section, choose Upload a template file.

      • Save the CloudFormation stack template file, and then upload it here.

    3. Choose Next and provide the following information.

      • WebAppEndpoint: copy the value from your web app

      • AccessEndpoint: provide the custom domain name that you want to use

      • AcmCertificateArn: provide the ARN for a public or private SSL/TLS certificate that is stored in AWS Certificate Manager

    4. Complete the AWS CloudFormation wizard until your new stack is created.

  2. In your web app, edit the Access endpoint, updating the Custom URL to the URL that you want to use.

  3. Create DNS records to route traffic for your custom domain name to the CloudFront distribution. If you're using Route 53 for the zone, you can create an Alias or CNAME record to the CloudFront distribution name (for example, xxxx.cloudfront.net). For information about using Amazon Route 53 with CloudFront, see Configuring Amazon Route 53 to route traffic to a CloudFront distribution.

  4. Update your cross-origin resource sharing policy by replacing the default access endpoint with the following line in the AllowedOrigins code block:

     "https://custom-url"

    You need to make this change for each bucket used by your web app.

    After you make your update, the AllowedOrigins section of your CORS policy should look like the following:

    "AllowedOrigins": [
    "https://custom-url"],

    You need only a single AllowedOrigins entry for each Transfer Family web app.

    See the Set up Cross-origin resource sharing (CORS) for your Amazon S3 bucket procedure for more details.
