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://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

Solution 1

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:

http://docs.aws.amazon.com/AmazonS3/latest/dev/VirtualHosting.html

Update 2019 : AWS SUBDOMAIN hosting in S3

As of today following steps worked to have a successfully working subdomain for AWS S3 hosted static website:

1. Create a bucket with subdomain name. In this example www.subtest.mysite.com

Note: Make sure on 'Permission' tab of bucket:

1.Block public access (bucket settings) 2.Access Control List & 3.Bucket policy are appropriately set to make sure bucket is public. ( Assuming you already did this for your root domain bucket, those settings can be mirrored on this subdomain bucket)

2. Upload the index.html file in the bucket

3. Create a CNAME record with your domain provider

Solution 3

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!

optimal. So done that I'll be able to use the address for the pictures as well: "images.mydomain.com.br / image.jpg"?

I already made ​​this appointment on route 53, however the subdomain does not show anything yet. it takes a while, or should I configure something in nginx? Thank you

No need to configure nginx for anything. It can take a while because of the DNS cache. You can try to validate that the DNS is set up correctly by running dig images.mydomain.com.br and checking the response. Clearing your DNS cache might also help to see the changes faster.

Thanks. Just noting that I needed to use s3-eu-west-1.amazonaws.com. for a bucket in Ireland. I didn't need the bucket name as a prefix.

how long does it usually take?
