How to apply CDN with cloudfront - router 53 => lightsail instance

Question

i am newbie to AWS and i am struggling set up subdomain access , my materials are :

• Route 53 : my domain is tranthanhbao.com

• Lightsail instance : 18.140.2.35 . I already set up nginx reverse proxy and in Route 53 point aws.tranthanhbao.com to 18.140.2.35 with A - ipv4 . It work well MY setting in Route 53 to 18.140.2.35 :
  

• Cloudfront : now i want to apply cloudfront to my domain aws.tranthanhbao.com (http will redirect to https) with below setting

Then when we access dsor8zoqxftko.cloudfront.net, it works well but i check domain ip , it show :

• [http://dsor8zoqxftko.cloudfront.net/] : this is from France and automatic redirect http to https. So it works well BUT
• [http://aws.tranthanhbao.com/] : still http and from my Lightsail instance IP .

So my question is how can I apply aws.tranthanhbao.com with cloudfront, not Link: [http://dsor8zoqxftko.cloudfront.net/]

Answer 1

You can try below steps:

1. Point 18.140.2.35 to some other name like origin.tranthanhbao.com origin.tranthanhbao.com --> 18.140.2.35
2. Define origin.tranthanhbao.com as an Origin of CloudFront instead of aws.tranthanhbao.com
3. Modify Route Record for aws.tranthanhbao.com and Choose Alias record (A record) and choose CloudFront distribution.
