Accessing Amazon S3 API without using an SDK

Accessing Amazon S3 without CLI or SDK

Overview

This project offers a reference for calling Amazon S3 REST API without using the AWS CLI or SDK. It supports Signature Version 4 for signing AWS requests to S3 API. Sometimes, a client environment is restricted and is unallowed to install any external packages or modules. In such a case, installing AWS CLI or an AWS SDK such as Boto3 for Python is not feasible. Assuming Python runtime is available (which is the case in most Unix-like OS environments), the s3.py program from this project can be modified and executed to invoke various S3 APIs.

Amazon S3 API Invoked

The following S3 APIs are called from the program:

• PutObject
• GetObject
• DeleteObject
• ListObjects
• ListBuckets
• CreateBucket
• DeleteBucket

More APIs can be added easily to s3.py by referencing the REST API syntax documented here.

Installation

Note: s3.py has been tested with Python 2.7 and Python 3.7. Please report any issues running the code.

1. Configure required environment variables

export AWS_ACCESS_KEY_ID=[your access key id]
export AWS_SECRET_ACCESS_KEY=[your access key secret]
export AWS_S3_BUCKET=[your bucket name]

2. Clone this repo or download s3.py file, and copy to your Linux machine
3. Run the program as python s3.py or python2.7 s3.py
