Configure Object Storage with the S3 API
The Swift3 middleware emulates the S3 REST API on top of
Object Storage.
The following operations are currently supported:
GET Service
DELETE Bucket
GET Bucket (List Objects)
PUT Bucket
DELETE Object
GET Object
HEAD Object
PUT Object
PUT Object (Copy)
To use this middleware, first download the latest
version from its repository to your proxy
server(s).
$ git clone https://github.com/stackforge/swift3.git
Then, install it using standard python mechanisms, such
as:
# python setup.py install
Alternatively, if you have configured the Ubuntu Cloud
Archive, you may use:
# apt-get install swift-python-s3
To add this middleware to your configuration, add the swift3
middleware in front of the swauth middleware, and before any other
middleware that look at Object Storage requests (like rate limiting).
Ensure that your proxy-server.conf file contains
swift3 in the pipeline and the [filter:swift3]
section, as shown below:
[pipeline:main]
pipeline = healthcheck cache swift3 swauth proxy-server
[filter:swift3]
use = egg:swift3#swift3
Next, configure the tool that you use to connect to the
S3 API. For S3curl, for example, you must add your
host IP information by adding your host IP to the
@endpoints array (line 33 in s3curl.pl):
my @endpoints = ( '1.2.3.4');
Now you can send commands to the endpoint, such
as:
$ ./s3curl.pl - 'a7811544507ebaf6c9a7a8804f47ea1c' -key 'a7d8e981-e296-d2ba-cb3b-db7dd23159bd' -get - -s -v http://1.2.3.4:8080
To set up your client, ensure you are using the ec2 credentials,
which can be downloaded from the API Endpoints tab
of the dashboard.
The host should also point to the Object Storage storage node's hostname. It also
will have to use the old-style calling format, and not the hostname-based container format.
Here is an example client setup using the Python boto library on a locally installed
all-in-one Object Storage installation.
connection = boto.s3.Connection(
aws_access_key_id='a7811544507ebaf6c9a7a8804f47ea1c',
aws_secret_access_key='a7d8e981-e296-d2ba-cb3b-db7dd23159bd',
port=8080,
host='127.0.0.1',
is_secure=False,
calling_format=boto.s3.connection.OrdinaryCallingFormat())
