I am having my bucket on Amazon S3 where I have uploaded certains files.
I have a sort public visitation on the page.
Is there any way to get the all visitations in log file
or Can I download the log file from the Amazon?
You can create logging for S3 bucket at the creation of bucket itself also after creating bucket. You need to specify the path for log file to store.You can refer http://docs.aws.amazon.com/AmazonS3/latest/UG/ManagingBucketLogging.html for steps.

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 get a file from s3 bucket with golang. What's special in my request is that I need to get a file from the root of the s3. i.e, in my situation, i have a buckets folder which is the root for the s3, inside that i have folders and files. I need to get the files from the buckets folder. it means that i don't have a bucket folder because i access only to the root.
the code im trying is:
numBytes, err := downloader.Download(file, &s3.GetObjectInput{
Bucket: aws.String("/"),
Key: aws.String("some_image.jpeg"),
})
The problem is I got an error that says the object does not exist.
Is it possible to read files from the root of s3? What do I need to write in the bucket? the key is written okay?
Many thanks for helping!
All files in S3 are stored inside buckets. You're not able to store a file in the root of s3.
Each bucket is its own distinct namespace. You can have multiple buckets in your Amazon account, and each file must belong to one of those buckets.
You can either create a bucket using the AWS web interface, command line tools or API. (Or 3rd party software like Cyberduck).
You can read more about buckets in S3 here: https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingBucket.html
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
I am trying to deploy a Lambda function to AWS from S3.
My organization currently does not provide the ability for me to upload files to the root of an S3 bucket, but only to a folder (ie: s3://application-code-bucket/Application1/).
Is there any way to deploy the Lambda function code through S3, from a directory other than the bucket root? I checked the documentation for Lambda's CreateFunction AWS command and could not find anything obvious.
You need to zip your lambda package and upload to S3 in any folder.
You can then provide an https S3 url of the file to upload to lambda
function.
The S3 bucket needs to be in the same region as that of the lambda
function.
Make sure you zip from the folder, i.e when the package is unzipped,
the files should be extracted in the same directory as the unzip
command, and should not create a new directory for the contents.
I have this old script of mine that I used to automate lambda deployments.
It needs to be refactored a bit, but still usable.
It gets as input the lambda name and the zip file path located locally on your PC.
It uploads it to S3 and publishes to the AWS Lambda.
You need to set AWS credentials with IAM roles that allows:
S3 upload permission
AWS Lambda update permission
You need to modify the bucket name and the path you want your zip to be uploaded to. (lines 36-37).
That's it.
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.
