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.
