image-utils

Utils to manipulate ceph ceph image.

currently there are two seperate modules. they have no relations.

Install

print version:

from image_utils import version

version.version_string()

Usage

currently there are two modules.

ceph.py

this module is used to interact with ceph image.

Example: copy a image from source ceph cluster to dest ceph.

from image_utils import ceph

# get source store.
src_store = ceph.get_store(conffile_path, ceph_user, keyring_path)

# get dest store.
dst_store = ceph.get_store(conffile_path2, ceph_user, keyring_path2)

# get an image location from source ceph pool.
src_loc = src_store.get_location(pool, image_name)

# copy image from src_store to dst_store, in dst_pool
ceph.copy(src_store, src_loc, dst_store, dst_pool)

fish.py

this module is used to modify disk image. require guestfs. while guestfs python bindings are not found in pypi, you should install rpm package

yum install python-libguestfs

Then you are ready

Example: modify a image.

from image_utils import fish

f = fish.Fish(mon_host, mon_port, client, key, pool, image_name)
f.launch()

f.add_mtu('192.168.1.100', 1450)
f.remove_file('/root/abc.txt')

f.shutdown()

while there are few apis in Fish class, tweak the class and add more apis as your wish.
