I want to download the file from a public S3 bucket using AWS console. When I put the below in the browser but getting an error. Wanted to visually see what else is there in that folder and explore
Public S3 bucket :
s3://us-east-1.elasticmapreduce.samples/flightdata/input
It appears that you are wanting to access an Amazon S3 bucket that belongs to a different AWS account. This cannot be done via the Amazon S3 management console.
Instead, I recommend using the AWS Command-Line Interface (CLI). You can use:
aws s3 ls s3://flightdata/input/
That will show you the objects stored in that bucket/path.
You could then download the objects with:
aws s3 sync s3://flightdata/input/ input

Binance made its data public through an s3 endpoint. The website is 'https://data.binance.vision/?prefix=data/'. Their bucket URL is 'https://s3-ap-northeast-1.amazonaws.com/data.binance.vision'. I want to download all the files in their bucket to my own s3 bucket. I can:
crawl this website and download the CSV files.
make a URL builder that builds all the URLs and downloads the CSV files using those URLs.
Since their data is stored on s3. I wonder if there is a cleaner way to sync their bucket to my bucket.
Is the third way really doable?
If you want to copy it to your own s3 bucket, you can do:
aws s3 sync s3://data.binance.vision s3://your-bucket-name --no-sign-request
If you want to copy it to your own computer into your current folder (.) you can do:
aws s3 sync s3://data.binance.vision . --no-sign-request
I'm trying to use an S3 bucket to upload files to as part of a build, it is configured to provide files as a static site and the content is protected using a Lambda and CloudFront. When I manually create files in the bucket they are all visible and everything is happy, but when the files are uploaded what is created are not available, resulting in an access denied response.
The user that's pushing to the bucket does not belong in the same AWS environment, but it has been set up with an ACL that allows it to push to the bucket, and the bucket with a policy that allows it to be pushed to by that user.
The command that I'm using is:
aws s3 sync --no-progress --delete docs/_build/html "s3://my-bucket" --acl bucket-owner-full-control
Is there something else that I can try that basically uses the bucket permissions for anything that's created?
According to OP's feedback in the comment section, setting Object Ownership to Bucket owner preferred fixed the issue.
I have a requirement of accessing S3 bucket on the AWS ParallelCluster nodes. I did explore the s3_read_write_resource option in the ParallelCluster documentation. But, it is not clear as to how we can access the bucket. For example, will it be mounted on the nodes, or will the users be able to access it by default. I did test the latter by trying to access a bucket I declared using the s3_read_write_resource option in the config file, but was not able to access it (aws s3 ls s3://<name-of-the-bucket>).
I did go through this github issue talking about mounting S3 bucket using s3fs. In my experience it is very slow to access the objects using s3fs.
So, my question is,
How can we access the S3 bucket when using s3_read_write_resource option in AWS ParallelCluster config file
These parameters are used in ParallelCluster to include S3 permissions on the instance role that is created for cluster instances. They're mapped into Cloudformation template parameters S3ReadResource and S3ReadWriteResource . And later used in the Cloudformation template. For example, here and here. There's no special way for accessing S3 objects.
To access S3 on one cluster instance, we need to use the aws cli or any SDK . Credentials will be automatically obtained from the instance role using instance metadata service.
Please note that ParallelCluster doesn't grant permissions to list S3 objects.
Retrieving existing objects from S3 bucket defined in s3_read_resource, as well as retrieving and writing objects to S3 bucket defined in s3_read_write_resource should work.
However, "aws s3 ls" or "aws s3 ls s3://name-of-the-bucket" need additional permissions. See https://aws.amazon.com/premiumsupport/knowledge-center/s3-access-denied-listobjects-sync/.
I wouldn't use s3fs, as it's not AWS supported, it's been reported to be slow (as you've already noticed), and other reasons.
You might want to check the FSx section. It can create an attach an FSx for Lustre filesystem. It can import/export files to/from S3 natively. We just need to set import_path and export_path on this section.
I need to send someone a link to download a folder stored in an amazon S3 bucket. Is this possible?
You can do that using the AWS CLI
aws s3 sync s3://<bucket>/path/to/folder/ .
There are many options if you need to filter specific files etc ... check the doc page
You can also use Minio Client aka mc for this. It is open source and S3 compatible. mc policy command should do this for you.
Set bucket to "download" on Amazon S3 cloud storage.
$ mc policy download s3/your_bucket
This will add downloadable policy on all the objects inside bucket name your_bucket and an object with name yourobject
can be accessed with URL below.
https://your_bucket.s3.amazonaws.com/yourobject
Hope it helps.
Disclaimer: I work for Minio
I have two aws account and i had sync s3 bucket between both account using below command but when i check images in both account do not have same permission i.e source account has public images for particular folder while target account do not have this.
