Utils to manipulate ceph ceph image.
currently there are two seperate modules. they have no relations.
Install
pip install image-utils
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.
