how appoint a subdomain for a s3 bucket?

问题:

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://s3-sa-east-1.amazonaws.com/nomeBucket/pasta/imag.png, and I access it through this same link.

Would that it were so: imagens.mydomain.com.br / folder / imag.png Is there any way I can do this? appoint a subdomain address to a bucket? I've tried the amazon route 53, as CNAME. I tried this: https://s3-sa-east-1.amazonaws.com/nomeBucket/

I took the test yesterday, but apparently it did not work. Someone already did something similar, and / or know how to help me?

Note: I'm using nginx. also need to configure it for subdomain?

Thank you

You need to rename your bucket to match the custom domain name (e.g. imagens.mydomain.com.br) and set up that domain as a CNAME to

<bucket-name>.s3.amazonaws.com.

(in your case imagens.mydomain.com.br.s3.amazonaws.com.

The full instructions are available here:

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!
