If you are hosting a static website using Amazon S3 and CloudFront and want to access it using a custom subdomain managed by Cloudflare, this guide will help you set it up. Follow these steps to map your subdomain (e.g., myprofile.insertcart.com) to your CloudFront distribution.

Step 1: Configure CloudFront

• Log in to AWS Console
  • Navigate to Amazon CloudFront.
  • Select your CloudFront distribution (e.g., d2n8x7g5r7tpl1.cloudfront.net).
• Add Your Subdomain as an Alternate Domain (CNAME)
  • Click on “Edit” in the General Settings.
  • In the Alternate Domain Names (CNAMEs) section, add your subdomain: myprofile.insertcart.com
  • Save the changes.

• Attach an SSL Certificate (Recommended for HTTPS)
  • Navigate to AWS Certificate Manager (ACM).
  • Request or import an SSL certificate for sandeep.insertcart.com.
  • Validate the certificate via DNS or email.
  • Once issued, return to CloudFront and attach the certificate.

• Save and Deploy Changes
  • Click Save Changes in CloudFront.
  • Wait for CloudFront to deploy the changes (this may take a few minutes).

Step 2: Configure Cloudflare DNS

1. Log in to Cloudflare
   • Go to the Cloudflare Dashboard and select your domain (insertcart.com).
2. Create a CNAME Record
   • Navigate to the DNS section.
   • Click Add Record.
   • Select CNAME as the record type.
   • Enter the following details: Name: myprofileTarget: d2n8x7g5r7tpl1.cloudfront.net Proxy Status: DNS only (Disable Cloudflare Proxy)
   • Click Save.
3. Wait for DNS Propagation
   • It may take a few minutes to a few hours for DNS changes to take effect.

Step 3: Test the Setup

Once everything is configured:

• Open your browser and visit https://myprofile.insertcart.com.
• If the setup is correct, your CloudFront-hosted website should load successfully.
• If not, clear Cloudflare Cache and your browser cache, then try again.

Troubleshooting Tips

• If HTTPS is not working, ensure you have a valid SSL certificate attached to CloudFront.
• If the domain does not resolve, check your Cloudflare DNS settings and confirm that the CNAME record is properly set.
• For mixed content issues, update your website assets to load via HTTPS.

Conclusion

By following these steps, you have successfully mapped your CloudFront distribution to a Cloudflare-managed subdomain. This setup ensures better performance, scalability, and security for your static website.
