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, andAWS_DEFAULT_REGIONenvironment 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'))

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