Writing json to file in s3 bucket

This code writes json to a file in s3, what i wanted to achieve is instead of opening data.json file and writing to s3 (sample.json) file,

how do i pass the json directly and write to a file in s3 ?

import boto3

s3 = boto3.resource('s3', aws_access_key_id='aws_key', aws_secret_access_key='aws_sec_key')
s3.Object('mybucket', 'sample.json').put(Body=open('data.json', 'rb'))
Solution

  • Amazon S3 is an object store (File store in reality). The primary operations are PUT and GET. You can not add data into an existing object in S3. You can only replace the entire object itself.

    For a list of available operations you can perform on s3 see this link http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectOps.html
