how appoint a subdomain for a s3 bucket?

Question

Good morning,

I am using amazon s3 bucket as the image server. And I want to use a subdomain of my site, how to address this bucket. eg: a picture is now in: https:/

Answer 1

I'm going to build on the other answers here for completeness.

I have moved my bucket to a subdomain so that the contents can be cached by Cloudflare.

• Old S3 Bucket Name: autoauctions
• New S3 Bucket Name: img.autoauctions.io
• CNAME record: img.autoauctions.io.s3.amazonaws.com

Now you'll need to copy all of your objects since you cannot rename a bucket. Here's how to do that with AWS CLI:

pip install awscli
aws configure

• Go to https://console.aws.amazon.com/iam/home and create a user or go to an existing user
• Go to the user's Security credentials tab
• Click Create access key. Copy the secret.
• Here's a list of AWS regions.

Now you'll copy your old bucket contents to your new bucket.

aws s3 sync s3://autoauctions s3://img.autoauctions.io

I found this to be too slow for the 1TB of images I needed to copy, so I increased the number of concurrent connections and re-ran from an EC2 instance.

aws configure set default.s3.max_concurrent_requests 400

Sync it up!

Want to make folders within your bucket public? Create a bucket policy like this:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicReadGetObject",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::img.autoauctions.io/copart/*"
        },
        {
            "Sid": "PublicReadGetObject",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::img.autoauctions.io/iaai/*"
        }
    ]
}

And now the image loads from img.autoauctions.io via Cloudflare's cache.

Hope this helps some people!
