The default endpoint & URL for an AWS hosted website is http://*username*.s3-website-us-east-1.amazonaws.com/index.html
But I have seen some like this https://s3.amazonaws.com/username/index.html
how do you do this?
You can always access an s3 hosted resource at:
http://s3.amazonaws.com/<bucket name>/<resource key (usually a filename)>
+1 for free-dom's answer...
...but even cooler is that you can use your own host/domain to access the content of the bucket.
Step 1. Create a bucket named, say, img.example.com, where you control the DNS for that domain.
Step 2. Add a CNAME entry in DNS that maps img.example.com to s3.amazonaws.com.
Step 3. There is no Step 3.
You can then access the files in that S3 bucket using http://img.example.com/FILENAME
This protects you in the event you want to change where your files are hosted to somewhere other than S3 (e.g., Amazon CloudFront CDN or another provider).

I have a Laravel application hosted on a domain. I have several dynamic directories ie:
example.com/directory
example.com/random
example.com/moon
I would like each of these directories to resolve to a different s3 bucket while masking the URL (I want to see the URL above, not the s3 bucket URL). What's the best way to accomplish this? I could possibly create a primary bucket and host example.com on it and create routing rules on that s3 bucket to redirect to the other s3 buckets (I think). What do those routing rules look like? I was unable to find directions in the AWS documentation that showed how to redirect to other buckets. Is there another, more simple way to go about this?
It's worth noting the Laravel application may not need to be involved in the actual routing as much as using the AWS sdk to dynamically configure the directories.
You have to use Route53 along with S3 enabling static website hosting.
For detail configuration about static website hosting in S3, you can take a look here.
After that choose Route53 as a service in AWS Console.
Select your hosted zone and add a CNAME recordset, in the value field enter the S3 bucket endpoint url and in the Name field enter the url that you want to point to the S3 bucket.
For using Route53 you can read this AWS document.
The best way would be to create a CloudFront (CF) distribution with three different origins. Then each origin would respond to different Origin Path which would lead to different buckets.
example.com could be defined in Route53, with Alias A record to the CF distribution. The benefit of using CF with S3 is that you not only can speed up your website (CF is CDN), but also you can keep your buckets and objects private:
Amazon S3 + Amazon CloudFront: A Match Made in the Cloud
I have created a hosted zone: "abc.com" and 2 s3 buckets: "app1.abc.com" and "app2.abc.com" with respective index.html. I am able to accesss individual default s3 website successfully (ex: app1.abc.com.s3-website-ap-southeast-1.amazonaws.com and app2.abc.com.s3-website-ap-southeast-1.amazonaws.com)
Now, How to create record sets to redirect traffic lets say if "app1.abc.com" called, then index.html of "app1.abc.com" bucket should be accessed. If "app2.abc.com" called, then index.html of "app2.abc.com" bucket should be accessed.
Is it possible to do with s3 and route53? If not any other ways to redirect traffic based on url to s3 bucket?
I went through documentation but no clue. Appreciate for help.
You simply need to create a CNAME record that point app1.abc.com to app1.abc.com.s3-website-ap-southeast-1.amazonaws.com. The procedure is the same for the second bucket.
For documentation, see https://docs.aws.amazon.com/AmazonS3/latest/dev/VirtualHosting.html#VirtualHostingCustomURLs
I'm new to AWS and all of it's services and my first go at it I started my project with a S3 bucket that was created by default by AWS Vue CLI. I've got Cognito pool & gateway API connected to this bucket but now that I want to connect this project to a custom domain I just purchased I realize the bucket name needs to match the root domain name. From what I understand this will mean that I need to pull all non-aws files from my Vue project, duplicate it, and either reconfigure pre-existing connections or start all over.
I've got my custom domain set up with an empty S3 bucket, Cloudfront, and Router 53 so that's up and working but now I am not sure how to go about transferring this project from buckets.
So basically I started my project with Bucket1 and finished everything that included Cognito Pool & Gateway API. Now I have a custom domain I want to use have Cloudfront and Route 53 with CustomDomain bucket name and I want to have the project from Bucket1 load for the new bucket.
Using Cloud-front you can mitigate this issue.
Route 53(DNS Name) --> Cloudfront Url --> S3 origin
As you already created a bucket for website hosting, below steps can help you.
Use the Amazon S3 console t to login and search for CloudFront.
Click on Create distribution
Create a Web distribution
Select existing bucket in Origin Domain Name and complete the setup.
Update the DNS records for your domain to point your website's CNAME to your CloudFront distribution's domain name. You can find your distribution's domain name in the CloudFront console in a format that is similar to d1234abcd.cloudfront.net.
Wait for your DNS changes to propagate and for the previous DNS entries to expire.
The typical AWS way to do this is to use cloudfront - the domain points to cloudfront and cloudfront can point to any bucket name or other source location; when you introduce cloudfront into the mix, the bucketname no longer needs to match the domain name.
I want to connect CDN to an AWS S3 Bucket, but the AWS Document indicates that the bucket name must be the same as the CNAME. Therefore, it is very easy to guess the real s3 bucket url by others.
For example,
- My domain: example.com
- My S3 Bucket name: image.example.com
- My CDN CNAME(image.example.com) will point to image.example.com.s3.amazonaws.com
After that, people can access the CDN URL -> http://image.example.com to obtain the resources from my S3 Bucket. However, under this restriction, people can guess my real S3 bucket url from the CNAME (CNAME + s3.amazonaws.com) easily.
So, my question is that how can I hide my real s3 bucket url? Because I don't want to expose my real S3 url to anyone for preventing any attacks.
I am not sure I understand what you are asking for or what you are trying to do [hiding your bucket does not really help anything], however I will attempt to answer your question regarding "hiding" your bucket name. Before I answer, I would like to ask these two questions:
Why do you want to hide your S3 bucket url?
What kind of attacks are you trying to prevent?
You are correct that the S3 bucket name had to be the same as your URL. This is no longer a requirement as you can mask the S3 bucket using cloudfront. CloudFront as you know is a CDN from AWS. Thus the bucket name could be anything (randomstring).
You can restrict access to the bucket, such that only CloudFront can access it. Data in the bucket is then replicated to edge locations and served from there. Even if one knows the S3 URL, it will not do anything as access to the s3 bucket is restricted, an IAM rule grants CloudFront access and no one else.
Access restriction is done via origin access and while you can manually configure this using a bucket policy, you can also set a flag in CloudFront to do this on your behalf. More information is available here.
Use the CloudFront name in Route53. Do not use CNAME, but rather use A type, and set it up as an Alias. For more information see this document.
If you are using a different DNS provider, AWS aliases will naturally not be available. I suggest moving the zone file from your other provider to AWS. If you cannot do this, then you can still use a CNAME. Again see here for more information.
I suggest using your own domain name for CloudFront and setting up HTTPS. AWS offers certificates at no additional cost for services within AWS. You can register a certificate for your domain name which is either validated by a DNS entry or an Email. To set this up please see this document.
If you want to restrict access to specific files within AWS, you can use signed URLs. More information about that is provided here.
Is it possible to host multiple subdomains from a single bucket folders?
Example -
Lets assume bucketname is my aws s3 bucket.
To access the site url is - http://bucketname.s3.amazonaws.com.
Now lets assume i have 5 folders inside it - a,b,c,d & e.
Can i create subdomains pointing to their respective folders inside the s3 bucket. Like -
http://a.bucketname.s3.amazonaws.com site works from folder a of the bucket
http://b.bucketname.s3.amazonaws.com site works from folder b of the bucket
http://c.bucketname.s3.amazonaws.com site works from folder c of the bucket
and so on.
Is it possible ?
Amazon S3 alone cannot do what you ask for.
The URL will point to only one bucket.
Typically, however, people want a Custom URL to point to content. For example, you could point mycompanyname.com to Amazon S3. This involves:
Owning the domain name
Creating a bucket with a name that matches the domain name (thus, you'd need one bucket per domain/subdomain)
Configuring the DNS entry (in Amazon Route 53 or your own DNS provider) to with a CNAME that points to the S3 bucket
Alternatively, behaviours can be configured in Amazon CloudFront that can present content from various back-ends.
Naming conventions for bucket URL are fixed by AWS. You cannot change to subdomain URL. You can use CloudFront to host it in your own domain or it can host under *.cloudfront.net.
Subdomain for cloudfront is also random. Will look like the following.

Hope it helps.
