Openstack-glance partial implementations and examples of API image management

openstack-glance API

for convenience, you can customize a function first put it in the credentials.py .

# VI credentials.py

#!/usr/bin/env python

Import OS

Def get_keystone_creds ():

d = {}

d[' username ' =os.environ[' os_username ']

d[' password ' =os.environ[' Os_password ']

d[' auth_url ' =os.environ[' Os_auth_url ']

d[' tenant_name ') = os.environ[' Os_tenant_name ']

return D

Def get_nova_creds ():

d = {}

d[' username ' =os.environ[' os_username ']

d[' api_key ' =os.environ[' Os_password ']

d[' auth_url ' =os.environ[' Os_auth_url ']

d[' project_id ']= os.environ[' os_tenant_name ']

return D

Use API when

Import Keystoneclient.v2_0.client as Ksclient

Import Glanceclient

Import Glanceclient.v2.client as Glclient

From credentials import Get_keystone_creds

( 1 ) query virtual machine information   

images = glance.images.list () Get img the queue

images.next () output in sequence

Part of the code:

Creds = Get_keystone_creds ()

Keystone = Ksclient. Client (**creds)

Glance_endpoint=keystone.service_catalog.url_for (service_type= ' image ', endpoint_type= ' PublicURL ')

Glance = glclient. Client (Glance_endpoint,token=keystone.auth_token)

Images = Glance.images.list ()

Print Images

Print Images.next ()

(2) Upload img

With Open (Img_url) as Fimage: #img_url Image Storage Path

glance.images.create (name="Cirros_zy", is_public=true,disk_format="Qcow2", Container_ format="Bare", Data=fimage)

Part of the code:

Keystone = Ksclient. Client (**creds)

Glance_endpoint=keystone.service_catalog.url_for (service_type= ' image ', endpoint_type= ' PublicURL ')

Glance=glanceclient. Client (' 1 ', Glance_endpoint,token=keystone.auth_token)

With open (Img_url) as Fimage:

Glance.images.create (name= "Cirros_zy", is_public=true,disk_format= "Qcow2", container_format= "bare", data=fimage)

( 3 ) Delete img

Glance.images.delete (image_id)

( 4 ) member Bindings

Glance.image_members.create (Image_id,mem_id,can_share=true)

( 5 ) member Delete

Glance.image_members.delete (image_id,mem_id)

( 6 ) img Download

because glance v2 does not support the image download API , it is directly downloaded using the command line

The code is as follows:

Import OS

string_1 = ' glance image-download--file ' + image_url + ' + image_id

Os.system (string_1)
