python-cephclient is a python module to communicate with Ceph's REST API (ceph-rest-api).

This is currently a work in progress.

ABOUT

Client

The cephclient class takes care of sending calls to the API through HTTP and handle the responses. It supports queries for JSON, XML, plain text or binary.

Wrapper

The wrapper class extends the client and provides helper functions to communicate with the API.

Nothing prevents you from calling the client directly exactly like the wrapper does. The wrapper exists for convenience.

HOW TO USE

Installation

Install the package through pip:

pip install python-cephclient

Installation does not work ?

python-cephclient depends on lxml which itself depends on some packages. To install lxml's dependencies on Ubuntu:

apt-get install python-dev libxml2-dev libxslt-dev

Instanciate CephWrapper:

from cephclient.wrapper import *

wrapper = CephWrapper(
    endpoint = 'http://apiserver:5000/api/v0.1/',
    debug = True # Optionally increases the verbosity of the client
)

Do your request and specify the reponse type you are expecting.

Either json, xml, text (default) or binary are available.

json:

response, body = wrapper.get_fsid(body = 'json')
print('Response: {0}, Body:\n{1}'.format(response, json.dumps(body, indent=4, separators=(',', ': '))))

====

Response: <Response [200]>, Body:
{
    "status": "OK",
    "output": {
        "fsid": "d5252e7d-75bc-4083-85ed-fe51fa83f62b"
    }
}

xml:

response, body = wrapper.get_fsid(body = 'xml')
print('Response: {0}, Body:\n{1}'.format(reponse, etree.tostring(body, pretty_print=True)))

====

Response: <Response [200]>, Body:
<response>
  <output>
    <fsid><fsid>d5252e7d-75bc-4083-85ed-fe51fa83f62b</fsid></fsid>
  </output>
  <status>
    OK
  </status>
</response>

text:

response, body = wrapper.get_fsid(body = 'text')
print('Response: {0}, Body:\n{1}'.format(response, body))

====

Response: <Response [200]>, Body:
d5252e7d-75bc-4083-85ed-fe51fa83f62b

binary:

response, body = wrapper.mon_getmap(body = 'binary')
# < Do something binary with 'body' >
