BucketStore is a very simple Amazon S3 client, written in Python. It aims to be much more straight-forward to use than boto3, and specializes only in Amazon S3, ignoring the rest of the AWS ecosystem.

Features

  • Treats S3 Buckets as Key/Value stores.
  • Automatic support for AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_DEFAULT_REGION environment variables.
  • Easily make keys (or entire buckets) publically accessable.
  • Easily get the public URL for a given key.
  • Generates temporary URLs for a given key.
  • Use S3 in a pythonic way!

Usage

Installation

$ pip install bucketstore

Get (or create) a bucket, easily:

import bucketstore

# Create the bucket if it doesn't exist.
bucket = bucketstore.get('bucketstore-playground', create=True)

Treat the bucket like a key/value store:

>>> bucket
<S3Bucket name='bucketstore-playground'>

# get/set using array syntax
>>> bucket['foo'] = 'bar'
>>> bucket['foo']
bar

# get/set using methods
>>> bucket.set('foo2', 'bar2')
>>> bucket.get('foo2')
bar2

# list keys
>>> bucket.list()
[u'foo', u'foo2']

# all keys
>>> bucket.all()
[<S3Key name=u'foo' bucket='bucketstore-playground'>, <S3Key name=u'foo2' bucket='bucketstore-playground'>]

# check if a key exists in the bucket
>>> 'foo' in bucket
True

# delete keys in the bucket
>>> del bucket['foo2']
{}

Interact with S3 keys:

>>> bucket.key('foo')
<S3Key bucket='bucketstore-playground' name=u'foo'>

>>> foo = _
>>> foo.set('new value')

# Generate a temporary share URL.
>>> foo.temp_url(duration=1200)
u'https://bucketstore-playground.s3.amazonaws.com/foo?AWSAccessKeyId=AKIAI2RVFNXIW7WS66QQ&Expires=1485493909&Signature=L3gD9avwQZQO1i11dIJXUiZ7Nx8%3D'

# Make key publically accessable.
>>> foo.make_public()
>>> foo.url
'https://s3.amazonaws.com/bucketstore-playground/foo'

# Get / set metadata for key.
>>> foo.meta = {'foo': 'bar'}
>>> foo.meta
{'foo': 'bar}

# Rename key to 'foo3'.
>>> foo.rename('foo3')

# Delete the key.
>>> foo.delete()

# Create a key with a content type
>>> foo = bucket.key('foo.html')
>>> foo.set('<h1>bar</h1>', content_type='text/html')

# upload to key
>>> bucket.key('test.py').upload('/tmp/test.py')

# or upload with a file-like object! (make sure it's open in binary mode)
>>> with open('/tmp/test.py', 'rb') as file:
>>>     bucket.key('test.py').upload(file)

# download to file
>>> bucket.key('test.py').download('/tmp/test.py')

# or download to a file-like object! (make sure it's open in binary mode)
>>> with open('/tmp/test.py', 'wb') as file:
>>>     bucket.key('test.py').download(file)

# size of key
>>> bucket.key('test.py').size()
>>> len(bucket.key('test.py'))
15

Other methods include bucketstore.login(access_key_id, secret_access_key), bucketstore.list(), and bucketstore.get(bucket_name, create=False).

Tests

Tests are run through Tox.

# Run tests against all environments.
$ tox
# Run against a specific version.
$ tox -e py36
# Run with pytest arguments.
$ tox -- --pdb
