VM Profiles
|
|
===========
|
|
|
|
Salt cloud designates virtual machines inside the profile configuration file.
|
|
The profile configuration file defaults to ``/etc/salt/cloud.profiles`` and is
|
|
a yaml configuration. The syntax for declaring profiles is simple:
|
|
|
|
.. code-block:: yaml
|
|
|
|
fedora_rackspace:
|
|
provider: rackspace
|
|
image: Fedora 17
|
|
size: 256 server
|
|
script: bootstrap-salt
|
|
|
|
It should be noted that the ``script`` option defaults to ``bootstrap-salt``,
|
|
and does not normally need to be specified. Further examples in this document
|
|
will not show the ``script`` option.
|
|
|
|
A few key pieces of information need to be declared and can change based on the
|
|
public cloud provider. A number of additional parameters can also be inserted:
|
|
|
|
.. code-block:: yaml
|
|
|
|
centos_rackspace:
|
|
provider: rackspace
|
|
image: CentOS 6.2
|
|
size: 1024 server
|
|
minion:
|
|
master: salt.example.com
|
|
append_domain: webs.example.com
|
|
grains:
|
|
role: webserver
|
|
|
|
|
|
The image must be selected from available images. Similarly, sizes must be
|
|
selected from the list of sizes. To get a list of available images and sizes
|
|
use the following command:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt-cloud --list-images openstack
|
|
salt-cloud --list-sizes openstack
|
|
|
|
|
|
Some parameters can be specified in the main Salt cloud configuration file and
|
|
then are applied to all cloud profiles. For instance if only a single cloud
|
|
provider is being used then the provider option can be declared in the Salt
|
|
cloud configuration file.
|
|
|
|
|
|
Multiple Configuration Files
|
|
----------------------------
|
|
|
|
In addition to ``/etc/salt/cloud.profiles``, profiles can also be specified in
|
|
any file matching ``cloud.profiles.d/*conf`` which is a sub-directory relative
|
|
to the profiles configuration file(with the above configuration file as an
|
|
example, ``/etc/salt/cloud.profiles.d/*.conf``). This allows for more
|
|
extensible configuration, and plays nicely with various configuration
|
|
management tools as well as version control systems.
