Salt Cloud 0.6.0 Release Notes
|
|
==============================
|
|
|
|
The new Salt project, Salt Cloud, is introduced with version 0.6.0. Salt Cloud
|
|
has been developed to ease the automation and integration of Salt with public
|
|
cloud providers by allowing cloud vms to be cleanly defined, created and
|
|
automatically hooked back into a Salt Master.
|
|
|
|
While Salt Cloud is primarily made to build cloud vms to tie into a Salt Mater,
|
|
it has been created in a generic way, so that it can be used to provision and
|
|
hook systems of any type via the familiar Salt modules system.
|
|
|
|
This release supports three public cloud providers (all via libcloud),
|
|
Amazon EC2, Rackspace Cloud and Linode.
|
|
|
|
Documentation
|
|
=============
|
|
|
|
The documentation for Salt Cloud can be found on Read the Docs:
|
|
http://salt-cloud.readthedocs.org
|
|
|
|
Download
|
|
========
|
|
|
|
Salt Cloud can be downloaded and install via pypi or github:
|
|
|
|
https://pypi.python.org/packages/source/s/salt-cloud/salt-cloud-0.6.0.tar.gz
|
|
|
|
https://cloud.github.com/downloads/saltstack/salt-cloud/salt-cloud-0.6.0.tar.gz
|
|
|
|
Packages are not yet available, Salt Cloud requires three dependencies, the
|
|
salt libs, libcloud, and paramiko.
|
|
|
|
Extensible With Cloud Modules
|
|
=============================
|
|
|
|
The Salt loader system has been employed to make adding support for additional
|
|
public cloud systems just as modular and simple as adding support for new
|
|
package managers in Salt.
|
|
|
|
Adding support for a new cloud provider is extremely simple, just add a cloud
|
|
module and everything cleanly links together.
|
|
|
|
Define VM Profiles
|
|
==================
|
|
|
|
The way a vms is created is done via profiles. Profiles are used to define what
|
|
properties a vm will have, the cloud provider, the size and the image.
|
|
|
|
.. code-block:: yaml
|
|
|
|
centos_rackspace:
|
|
provider: rackspace
|
|
image: CentOS 6.2
|
|
size: 1024 server
|
|
os: RHEL6
|
|
minion:
|
|
grains:
|
|
role: webserver
|
|
master: salt.example.com
|
|
|
|
This profile will be used to create vms on Rackspace cloud with the CentOS 6.2
|
|
image and the Rackspace 1024 vm size. Particulars of the minion config can
|
|
also be specified.
|
|
|
|
Individual vms can be created from profiles:
|
|
|
|
.. code-block:: bash
|
|
|
|
# salt-cloud -p centos_rackspace web1
|
|
|
|
This command creates a vms with the name web1 on the Rackspace cloud and
|
|
connects the new vm to a Salt Master located at salt.example.com. The new VM
|
|
has the Salt id of web1.
|
|
|
|
Define Maps of Profiles
|
|
=======================
|
|
|
|
When it is desired to have a predefined mapping of many, or a specific group
|
|
of vms then a cloud map can be defined:
|
|
|
|
.. code-block:: yaml
|
|
|
|
centos_rackspace:
|
|
web1
|
|
web2
|
|
web3
|
|
web4
|
|
centos_linode:
|
|
redis1
|
|
riak1
|
|
riak2
|
|
riak3
|
|
ubuntu_ec2:
|
|
dev1
|
|
dev2
|
|
cassandra1
|
|
cassandra2
|
|
cassandra3
|
|
|
|
This map file will create vms named web 1-4 using the centos_rackspace profile
|
|
on rackspace, the redis and riak vms on linode and the dev and Cassandra vms on
|
|
ec2. It can be run with salt-cloud:
|
|
|
|
.. code-block:: bash
|
|
|
|
# salt-cloud -m mapfile
|
|
|
|
When creating more than one vm the -P option can be passed, to make the vms
|
|
provision in parallel, greatly speeding up large scale expansions of vms.
