S3 bucket with same CNAME as app?

Question

I have the following setup:

• Domain registered mydomain.com
• App hosted on EC2 webserver on port 80 that's a accessible right now at mydomain.com/myapp
• .csv files hosted on an S3 bucket named myapp at the following endpoint like so: s3-us-west-2.amazonaws.com/myapp/sample_file.csv
• Route 53 to deal with CNAME for my domain and an Elastic IP

Everything works fine. However, now I want to update the URL's in my app to mask the longer AWS prefix and replace it instead with: mydomain.com/myapp/sample_file.csv

Every tutorial I've seen deals with subdomains like: myapp.mydomain.com/sample_file.csv which I DON'T want (since this particular app should only be accessed at the /myapp URL)

Is this possible?

Answer 1

You could point a custom domain name to your Amazon S3 bucket. The basic steps are:

• Create an Amazon S3 bucket with a name that matches your domain name (eg dl.mydomain.com)
• Activate Static Website Hosting on the bucket
• Create a Record Set in Amazon Route 53 for the dl subdomain:
  • Type A
  • Alias = yes
  • Select the Static website for your bucket

Then, put objects in the bucket within the myapp directory, eg myapp/file.csv. You will then be able to access the file via: dl.mydomain.com/myapp/file.csv
