Ceph supports RESTful API that is compatible with the basic data access model of the Swift API. In the last section, we covered accessing the Ceph cluster via the S3 API; in this section, we will learn to access it via the Swift API.
To use Ceph object storage with the Swift API, we need the Swift subuser and secret keys that we created earlier in this chapter. This user information will then be passed using the Swift CLI tool in order to access Ceph object storage:
- On
client-node1, a virtual machine installs the python Swift client:# apt-get install python-setuptools # easy_install pip # pip install --upgrade setuptools # pip install --upgrade python-swiftclient
- Get the swift subuser and secret keys:
# radosgw-admin user info --uid mona - Access Ceph object storage by listing the default bucket:
# swift -A http://192.168.1.106:7480/auth/1.0 -U mona:swift -K 6vxGDhuEBsPSyX1E7vYvFrTXLVqoJByMHT+jnXPV list - Add a new bucket,
