Glossary¶
- CLI¶
Command-Line Interface; a textual user interface.
- compute¶
OpenStack Compute (Nova).
- container¶
One of the object-store resources; a container holds objects being stored.
- endpoint¶
A base URL used in a REST request. An authentication endpoint is specifically the URL given to a user to identify a cloud. A service endpoint is generally obtained from the service catalog.
- host¶
- identity¶
OpenStack Identity (Keystone).
- image¶
OpenStack Image (Glance). Also the attribute name of the disk files stored for use by servers.
- keypair¶
The attribute name of the SSH public key used in the OpenStack Compute API for server authentication.
- node¶
A logical system, may refer to a server (virtual machine) or a host.
Generally used to describe an OS instance where a specific process is running, e.g. a ‘network node’ is where the network processes run, and may be directly on a host or in a server. Contrast with host and server.
- object¶
A generic term which normally refers to the a Python
object. The OpenStack Object Store service (Swift) also uses object as the name of the item being stored within a container.- object-store¶
OpenStack Object Store (Swift).
- project¶
The name of the owner of resources in an OpenStack cloud. A project can map to a customer, account or organization in different OpenStack deployments. Used instead of the deprecated tenant.
- region¶
The attribute name of a partitioning of cloud resources.
- resource¶
A Python object representing an OpenStack resource inside the SDK code. Also used to describe the items managed by OpenStack.
- role¶
A personality that a user assumes when performing a specific set of operations. A role includes a set of rights and privileges that a user assuming that role inherits. The OpenStack Identity service includes the set of roles that a user can assume in the token that is issued to that user.
The individual services determine how the roles are interpreted and access granted to operations or resources. The OpenStack Identity service treats a role as an arbitrary name assigned by the cloud administrator.
- server¶
A virtual machine or a bare-metal host managed by the OpenStack Compute service. Contrast with host and node.
- service¶
In OpenStack this refers to a service/endpoint in the ServiceCatalog. It could also be a collection of endpoints for different regions. A service has a type and a name.
- service catalog¶
The list of services configured at a given authentication endpoint available to the authenticated user.
- tenant¶
Deprecated in favor of project.
- token¶
An arbitrary bit of text that is used to access resources. Some tokens are scoped to determine what resources are accessible with it. A token may be revoked at any time and is valid for a finite duration.
- volume¶
OpenStack Volume (Cinder). Also the attribute name of the virtual disks managed by the OpenStack Volume service.
