如何将AWS API Gateway定制域创建到已经在CloudFront分发中已使用且具有任何停机时间的域？

Question

I'm trying to switch my site, which is currently CloudFront and Elastic Beanstalk, to API Gateway.

When I try to create the Custom Domain in API Gateway I get a message that there is already a CloudFront distribution for that domain, which is true. But if I remove that distribution my site will be down until the new distribution (for the API Gateway) will be up.

Is there anyway I can swap these or something ?

I do have control over the DNS records.

Answer 1

You can register your API-Gateway as cloudfront origin and then assign a separate behavior for you API calls.

If you need a step-by-step guide, you can use the following link:

For a cloudformation setup you can use this description:

hosting a Cloudfront site with S3 and API Gateway

Answer 2

The solution that worked in the end :

1. Change the DNS to point directly at Elastic Beanstalk
2. Disable & Delete the original CloudFront distribution
3. Create a 'Custom Domain' in APIG (this also creates a CloudFront dist.)
4. Change the DNS to point at the new CloudFront dist. (you get the URL in the APIG console under Custom Domains)

Each of these steps takes a little time ... but there is no downtime.
