Compute relies on an external image service to store virtual machine images and maintain a catalog of available images. Compute is configured by default to use the OpenStack Image service (Glance), which is the only currently supported image service.
| Configuration option=Default value | (Type) Description |
| allowed_direct_url_schemes=[] | (ListOpt)A list of url scheme that can be downloaded directly via the direct_url. Currently supported schemes: [file]. |
| glance_api_insecure=False | (BoolOpt)Allow to perform insecure SSL (https) requests to glance |
| glance_api_servers=['$glance_host:$glance_port'] | (ListOpt)A list of the glance api servers available to nova. Prefix with https:// for ssl-based glance api servers. ([hostname|ip]:port) |
| glance_host=$my_ip | (StrOpt)default glance hostname or ip |
| glance_num_retries=0 | (IntOpt)Number retries when downloading an image from glance |
| glance_port=9292 | (IntOpt)default glance port |
| glance_protocol=http | (StrOpt)Default protocol to use when connecting to glance. Set to https for SSL. |
| osapi_glance_link_prefix=None | (StrOpt)Base URL that will be presented to users in links to glance resources |
If your installation requires the use of euca2ools for registering
new images, you will need to run the nova-objectstore service.
This service provides an Amazon S3 frontend for Glance, which is needed
because euca2ools can only upload images to an S3-compatible image
store.
