Using OpenStack Compute
|
||
=======================
|
||
|
||
Before working with the Compute service, you'll need to create a connection
|
||
to your OpenStack cloud by following the :doc:`connect` user guide. This will
|
||
provide you with the ``conn`` variable used in the examples below.
|
||
|
||
.. contents:: Table of Contents
|
||
:local:
|
||
|
||
The primary resource of the Compute service is the server.
|
||
|
||
List Servers
|
||
------------
|
||
|
||
A **server** is a virtual machine that provides access to a compute instance
|
||
being run by your cloud provider.
|
||
|
||
.. literalinclude:: ../examples/compute/list.py
|
||
:pyobject: list_servers
|
||
|
||
Full example: `compute resource list`_
|
||
|
||
List Images
|
||
-----------
|
||
|
||
An **image** is the operating system you want to use for your server.
|
||
|
||
.. literalinclude:: ../examples/compute/list.py
|
||
:pyobject: list_images
|
||
|
||
Full example: `compute resource list`_
|
||
|
||
List Flavors
|
||
------------
|
||
|
||
A **flavor** is the resource configuration for a server. Each flavor is a
|
||
unique combination of disk, memory, vCPUs, and network bandwidth.
|
||
|
||
.. literalinclude:: ../examples/compute/list.py
|
||
:pyobject: list_flavors
|
||
|
||
Full example: `compute resource list`_
|
||
|
||
List Networks
|
||
-------------
|
||
|
||
A **network** provides connectivity to servers.
|
||
|
||
.. literalinclude:: ../examples/network/list.py
|
||
:pyobject: list_networks
|
||
|
||
Full example: `network resource list`_
|
||
|
||
Create Key Pair
|
||
---------------
|
||
|
||
A **key pair** is the public key and private key of
|
||
`public–key cryptography`_. They are used to encrypt and decrypt login
|
||
information when connecting to your server.
|
||
|
||
.. literalinclude:: ../examples/compute/create.py
|
||
:pyobject: create_keypair
|
||
|
||
Full example: `compute resource create`_
|
||
|
||
Create Server
|
||
-------------
|
||
|
||
At minimum, a server requires a name, an image, a flavor, and a network on
|
||
creation. You can discover the names and IDs of these attributes by listing
|
||
them as above and then using the find methods to get the appropriate
|
||
resources.
|
||
|
||
Ideally you'll also create a server using a keypair so you can login to that
|
||
server with the private key.
|
||
|
||
Servers take time to boot so we call ``wait_for_server`` to wait
|
||
for it to become active.
