Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Words and Phrases
| Search for | Example | Results |
|---|---|---|
| A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
|
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Using Boolean Operators
| Search for | Operator | Example |
|---|---|---|
|
Two or more words in the same topic |
|
|
| Either word in a topic |
|
|
| Topics that do not contain a specific word or phrase |
|
|
| Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
| A combination of search types | ( ) parentheses |

Overview
OpenStack is an open-source cloud-computing platform for both public and private clouds. It controls large pools of compute, storage, and networking resources throughout a data center.
OpenStack is managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.
OpenStack discovery shows the state and configuration of your cloud using jclouds APIs. The discovery of these low-level infrastructure services are supported:
-
Nova (Compute)
- Manages the lifecycle of compute instances in an OpenStack environment.
- Its responsibilities include spawning, scheduling, and decommissioning of virtual machines on demand.
-
Neutron (Networking)
- Enables Network-Connectivity-as-a-Service for other OpenStack services, such as OpenStack Compute.
- Provides an API for you to define networks and attachments into them.
- Has a pluggable architecture that supports many popular networking vendors and technologies.
-
Cinder (Volume)
- Provides the persistent block storage to running instances.
- Its pluggable driver architecture facilitates the creation and management of block storage devices.
-
Glance (Image)
- Stores and retrieves virtual machine disk images. OpenStack Compute makes use of this during the instance provisioning.
-
Keystone (identity)
- Provides an authentication and authorization service for other OpenStack services.
- Provides a catalog of endpoints for all OpenStack services.
