CNAME - s3 bucket amazon

Question

I would like to use a subdomain instead of a direct url for my s3 bucket on amazon.com. So instead of uploading images via url like http://bucket-images.s3-eu-west-1.amazonaws.com/path/to/image.png , I would like to use http://assets.domain.com/path/to/image.png . I tried to set CNAME as follows:

 CNAME assets domain.com bucket-images.s3-eu-west-1.amazonaws.com 

But after installing this CNAME, I get this error from amazon when I visit the domain:

 <Error> <Code>NoSuchBucket</Code> <Message>The specified bucket does not exist</Message> <BucketName>assets.domain.com</BucketName> <RequestId>45646DFSDFSFASDF</RequestId> <HostId> dfasdcvcvd546456454ds5fasdf4ad5f64asdfasdfccdfgvggtg </HostId> </Error> 

Here they report a change to the name bucket: https://forums.aws.amazon.com/message.jspa?messageID=237562 But that doesn't make sense. I used to work on a project that used a bucket name that is completely different from the subdomain. So there has to be a way ... Anyone who can help me?

Answer 1

For S3, you need the name CNAME and bucket to match:

The bucket name must match the name CNAME. So, http://images.johnsmith.net/filename will be the same as http://images.johnsmith.net.s3.amazonaws.com/filename if CNAME was created to display images.johnsmith.net in images.johnsmith .net.s3.amazonaws.com

So, in your specific example, you need to specify the assets.domain.com bucket.

If you need more flexibility, you can create a CloudFront distribution for your S3 bucket and assign CNAME to your CloudFront distribution.

Additional information for @Samuel Neff:

Just remember your AWS S3 bucket name just like your CNAME Cloudflare record. Otherwise it will not work.

Here I tried and worked for me:

The old https://s3-eu-west-2.amazonaws.com/cdn.domain.com at http://cdn.domain.com
