aws_utils

Utilities for working with AWS tools

This repo contains functionality that's useful enough for me to want to wrap in a nice Python API. Currently, it supports the following:

• Copy to S3 bucket from local machine
• Copy from S3 bucket to local machine
• Move to S3 bucket from local machine

Setup

1. First, make sure you have an AWS account and access to all the assets you're interested in working with
2. Install this repo from this directory with pip install .
3. Run aws configure to add your credentials to the AWS client on your machine. You'll need:
   • Access Key ID
   • Secret Access Key ID
   • Default Region (I don't usually set this)
   • Default output format (I usually use json)
4. Import and use these utilities in your work!

If you have already entered your credentials, you can skip that step

Usage

From Python:

from aws_utils import S3Interface

# How many processes do you want to use? I usually choose N - 1, where N is the
# total number of cores my machine has (e.g. an machine with 8 cores means I
# use pool_size = 7.
# More processes means faster up/download, but may impact other processes
# running on your system
pool_size = 7
interface = S3Interface(pool_size)

# A few possible uses
interface.cp("BUCKET_NAME:src_directory", "dst_directory", fnames="*.jpg")
interface.cp("src_directory", "BUCKET_NAME:dst_directory", fnames="*.mov")
interface.mv("BUCKET_NAME:src_directory", "dst_directory", fnames="invoice_*.txt")
interface.mv("src_directory", "BUCKET_NAME:dst_directory")

TODO

• Add to PyPI
• Transfer from one S3 bucket to another
