Endpoint listing middleware

The endpoint listing middleware enables third-party services that use data locality information to integrate with OpenStack Object Storage. This middleware reduces network overhead and is designed for third-party services that run inside the firewall. Deploy this middleware on a proxy server because usage of this middleware is not authenticated.

Format requests for endpoints, as follows:

/endpoints/{account}/{container}/{object}
/endpoints/{account}/{container}
/endpoints/{account}

Use the list_endpoints_path configuration option in the proxy_server.conf file to customize the /endpoints/ path.

Responses are JSON-encoded lists of endpoints, as follows:

http://{server}:{port}/{dev}/{part}/{acc}/{cont}/{obj}
http://{server}:{port}/{dev}/{part}/{acc}/{cont}
http://{server}:{port}/{dev}/{part}/{acc}

An example response is:

http://10.1.1.1:6000/sda1/2/a/c2/o1
http://10.1.1.1:6000/sda1/2/a/c2
http://10.1.1.1:6000/sda1/2/a
