<title>OpenStack API Quick Start</title>
|

|
<para>The OpenStack system has several key projects that are
|
||||||
|
separate installations but can work together depending on your
|
||||||
|
cloud needs: OpenStack Compute, OpenStack Object Storage,
|
||||||
|
OpenStack Identity Service, and OpenStack Image Store. With
|
||||||
|
the TryStack OpenStack installation, the OpenStack Compute,
|
||||||
|
OpenStack Identity, and OpenStack Image Store projects are all
|

working together in the background of the installation. </para>

<title>OpenStack API Introduction</title>
|
||||||
|
<para>This page covers the basics for talking to your
|
||||||
|
OpenStack cloud through the Compute API after authorizing
|
||||||
|
with the Identity Service API. You can then build a cloud
|
||||||
|
by launching images and assigning metadata to instances,
|
||||||
|
all through the API. For an API reference of all the
|
||||||
|
possible commands, see the <link

<title>Getting Credentials</title>
|
||||||
|
<para>Credentials are a combination of your username,
|
||||||
|
password, and what tenant (or project) your cloud is
|
||||||
|
running under. You only need to generate an additional
|
||||||
|
token if you are interacting with your cloud directly with
|
||||||
|
API endpoints, and not with a client. Your cloud
|
||||||
|
administrator can give you a username and a password as
|
||||||
|
well as your tenant identifier so you can generate
|
||||||
|
authorization tokens. You can also get the tenant ID from
|
||||||
|
the Dashboard URLs, for example
|
||||||
|
https://trystack.org/dash/296/images/ indicates a tenant
|
||||||
|
ID of 296. </para>
|
||||||
|
<para>These tokens are typically good for 24 hours, and when
|
||||||
|
the token expires, you will find out with a 401
|
||||||
|
(Unauthorized) error and can request another token
|
||||||
|
programmatically. The general workflow goes something like

||||||

this: </para>

<para> The Domain Name System (DNS) is a system by

which Internet domain name-to-address and

address-to-name resolutions are determined. All
|

domains and their components, such as mail
|

|
servers, utilize DNS to resolve to the appropriate
|
||||||
|
locations. DNS servers are usually set up in a

master-slave relationship such that failure of the
|
||||||
|
master invokes the slave. DNS servers may also be
|

clustered or replicated such that changes made to

one DNS server are automatically propagated to
|

other active servers. </para>
