How to redirect non www to www in aws s3 bucket and cloudfront

Question

I know how to redirect/rewrite non-www to www using .htaccess in apache server. But I have no clue, about s3 bucket, and CloudFront. I have hosted the website on an s3 bucket using CloudFront.

How do I redirect all http://example.com/ requests to http://www.example.com

Answer 1

1. Create a www.example.com S3 bucket and place all the code in this bucket
2. Create a example.com S3 bucket and set redirect to www.example.com as mentioned in https://aws.amazon.com/blogs/aws/root-domain-website-hosting-for-amazon-s3/
3. Create CloudFront and configure with S3 bucket link of www.example.com and add cname entry only for www.example.com.
4. In Route 53 for www.example.com point alias as CloudFront link related to S3 bucket
5. In Route 53 for example.com point alias S3 bucket of example.com

Answer 2

There is a feature in S3 where you can to this. Select a bucket, in Properties under Static Web Hosting select Redirect all requests to another host name.

Update from comment: Add a cname in your domain setup for example.com to point to your bucket endpoint and a cname for your www.example.com to point to the cloudfront endpoint.
