Mengelola image

Mengelola image¶

Ketika bekerja dengan image di SDK, Anda akan memanggil metode glance dan nova.

Lihat daftar images¶

Untuk daftar image yang tersedia, panggil metode glanceclient.v2.images.Controller.list:

import glanceclient.v2.client as glclient
glance = glclient.Client(...)
images = glance.images.list()

Image metode akan mengembalikan generator Python, seperti yang ditunjukkan dalam interaksi berikut dengan interpreter Python:

>>> images = glance.images.list()
>>> images
<generator object list at 0x105e9c2d0>
>>> list(images)

Dapatkan image dengan ID¶

Untuk mengambil objek image dari ID-nya, sebut metode glanceclient.v2.images.Controller.get:

import glanceclient.v2.client as glclient
image_id = 'c002c82e-2cfa-4952-8461-2095b69c18a6'
glance = glclient.Client(...)
image = glance.images.get(image_id)

Dapatkan image dengan nama¶

Image service Python bindings tidak mendukung pengambilan obyek image dengan nama. Namun, Compute Python bindings mengaktifkan Anda untuk mendapatkan sebuah objek image dengan nama. Untuk mendapatkan obyek image dengan nama, sebut (call) metode novaclient.v2.images.ImageManager.find:

import novaclient.v2.client as nvclient
name = "cirros"
nova = nvclient.Client(...)
image = nova.images.find(name=name)

Upload image¶

Untuk mengupload image, panggil metode glanceclient.v2.images.ImageManager.create:

import glanceclient.v2.client as glclient
imagefile = "/tmp/myimage.img"
glance = glclient.Client(...)
with open(imagefile) as fimage:
  glance.images.create(name="myimage", is_public=False, disk_format="qcow2",
                       container_format="bare", data=fimage)
