<para>The cloud operator assigns roles to users. Roles determine
|
|
who can upload and manage images. The operator might restrict
|
|
image upload and management to only cloud administrators or
|
|
operators.</para>
|
|
<para>You can upload images through the glance client or the Image
|
|
Service API. You can also use the nova client to list images,
|
|
set and delete image metadata, delete images, and take a
|
|
snapshot of a running instance to create an image. After you
|
|
upload an image, you cannot change it.</para>
