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:

To use this middleware, first download the latest version from its repository to your proxy server(s).

$ git clone https://github.com/fujita/swift3.git

Optional: To use this middleware with Object Storage 1.7.0 and previous versions, you must use the v1.7 tag of the fujita/swift3 repository. Clone the repository, as shown previously, and run this command:

$ cd swift3; git checkout v1.7

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 - 'myacc:myuser' -key mypw -get - -s -v http://1.2.3.4:8080
        

To set up your client, the access key will be the concatenation of the account and user strings that should look like test:tester, and the secret access key is the account password. 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='test:tester',
    aws_secret_access_key='testing',
    port=8080,
    host='127.0.0.1',
    is_secure=False,
    calling_format=boto.s3.connection.OrdinaryCallingFormat())
