在 Route 53 和 S3 中使用国际化域名

Question

I would like to expose static web page hosted on Amazon S3 to the world under following address:

zolty.aaa

What's more, I would like to redirect users from following addresses:

zol-ty.aaa
żółty.aaa
żólty.aaa
... and all combinations of z-ż, o-ó, etc.. 

to the main address - zolty.aaa. Of course all domains were bought.

When it comes to first domain name it's quite easy.

1. Set up zolty.aaa in Route53 as ALIAS to zolty.aaa S3 bucket
2. Set up zol-ty.aaa in Route53 as ALIAS to zol-ty.aaa S3 bucket
3. Redirect all request (in S3 bucket settings) from zol-ty.aaa to zolty.aaa

Unfortunately it's not that simple if domain contains non ASCII characters.

Based on AWS documentation punycode should be used for internationalized domain names.

So now my domain looks as follows:

xn--ty-4ja03asj.aaa

I am able to create hosted zone in Route 53 with such name. Now I want to create S3 bucket and add ALIAS to this bucket in DNS (Route53). Based on Amazon documentation, the name of S3 bucket should be the same as domain name. So I'm creating bucket xn--ty-4ja03asj.aaa. But it's not visible in Route53 as a possible target of ALIAS.

How can I achieve described behaviour?

I will be grateful for help.

Answer 1

Check here What you need to do is:

1. Convert your domain to punycode : https://cryptii.com/pipes/punycode

2. Create a hosted zone and set that punycode as a domain name;

3. Add the nameservers from your hosted zone to the domain control panel ;

Answer 2

S3 buckets must be created using punycode with the initial xn-- removed.

The punycode name for the domain żółty.aaa would be xn--ty-4ja03asj.aaa . The S3 bucket created must therefore be ty-4ja03asj.aaa .

As an aside, if using Cloudfront you then set the origin as ty-4ja03asj.aaa.s3-website-<region>.amazonaws.com or if simply pointing from Route 53 use s3-website-<region>.amazonaws.com after having selected "Alias to S3 website endpoint".

Answer 3

Unfortunately S3 bucket names must not start with the prefix xn--

The need for having the same domain and bucket name only applies if you set it up through Route 53 directly. If you set it up with CloudFront the bucket and domain don't have to be identical.

I used one of the tutorials out there in order to associate my IDN with my s3 static website.
