Ceph Object Gateway
Ceph Object Gateway, also known as RADOS Gateway (RGW), is an object storage interface
built on top of the librados library to provide applications with a RESTful gateway
to Ceph storage clusters. Use this information to understand how to deploy, configure, and
administer a Ceph Object Gateway environment.
This uses a "Day Zero", "Day One", and "Day Two" organizational methodology, providing readers with a logical progression path.
Day Zero is where research and planning are done before implementing a potential solution.
Day One is where the actual deployment, and installation of the software happens.
Day Two is where all the basic, and advanced configuration happens.
- S3-compatibility
- Provides object storage functionality with an interface that is compatible with a large subset of the Amazon S3 RESTful API.
- Swift-compatibility
- Provides object storage functionality with an interface that is compatible with a large subset
of the OpenStack Swift API.
The Ceph Object Gateway is a service interacting with a Ceph storage cluster. Since it provides interfaces compatible with OpenStack Swift and Amazon S3, the Ceph Object Gateway has its own user management system. Ceph Object Gateway can store data in the same Ceph storage cluster used to store data from Ceph Block Device clients; however, it would involve separate pools and likely a different CRUSH hierarchy. The S3 and Swift APIs share a common namespace, so you can write data with one API and retrieve it with the other.
- Administrative API
- Provides an administrative interface for managing the Ceph Object Gateways.
Administrative API requests are done on a URI that starts with the
adminresource end point. Authorization for the administrative API mimics the S3 authorization convention. Some operations require the user to have special administrative capabilities. The response type can be either XML or JSON by specifying the format option in the request, but defaults to the JSON format.
