Salt Cloud 0.8.2 Release Notes
==============================

This is a great release for Salt Cloud! New cloud providers have been added,
and the deploy functionality has been embiggened! Read on to see the cromulent
new features.


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-0.8.2.tar.gz

https://cloud.github.com/downloads/saltstack/salt-cloud/salt-cloud-0.8.2.tar.gz

Some packages have been made available for salt-cloud and more on on their
way. Packages for Arch, and FreeBSD are being made available thanks to the
work of Christer Edwards, and packages for RHEL and Fedora are being created
by Clint Savage. Package availability will be announced on the salt mailing list.

Select Query Option
===================

The last release of Salt Cloud added the -F/--full query option, to display
all information available for a particular instance. We now also have the -S
or --select-query option, which lets you specify which fields to display. Any
fields not specified will not be displayed, and if you specify a field that
doesn't exist on a particular provider, it will be ignored for them. Just
add a query.selection option to /etc/salt/cloud like such:

.. code-block:: yaml

  query.selection:
    - id
    - state
    - public_ips
    - keyname
    - TOTALXFER

os vs script
============

In a cloud profile, you need to specify which deploy script to use to install
Salt on the newly-provisioned VM. The option for this has always been 'os', 
which has been confusing to some. As of this release, you may now specify
'script' instead of 'os'. If you specify both, the value for 'script' will be
used. See the SmartOS Deploy Script below for an example.

SmartOS Deploy Script
=====================

Of particular interest to Joyent users may be the new SmartOS deploy script.
Salt itself is not fully-supported on SmartOS just yet, in part because ZeroMQ
is also not yet supported. When this script is used for deployment, it will
automatically install the required libraries and build ZeroMQ, and then use
easy_install to install the latest versions of PyZMQ and Salt. To use this,
just specify SmartOS as the 'os' or 'script' option in your cloud.profiles:

.. code-block:: yaml

  joyent_smartos:
    provider: joyent
    size: Extra Small 512 MB
    image: smartos
    script: SmartOS

OpenStack and IBM Modules
=========================

Support has been added for clouds using OpenStack (OPENSTACK) and for IBM's
SmartCloud Enterprise (IBMSCE) offering. We know that people have already
started using the OpenStack module, because pull requests have already been
merged from the community. This module has been tested against both the HP
and the Rackspace implementations of OpenStack. This can be a tricky module
to configure, depending on your provider, so some examples are provided here:

.. code-block:: yaml

  # For HP
  OPENSTACK.identity_url: 'https://region-a.geo-1.identity.hpcloudsvc.com:35357/v2.0/'
  OPENSTACK.compute_name: Compute
  OPENSTACK.compute_region: 'az-1.region-a.geo-1'
  OPENSTACK.tenant: myuser-tenant1
  OPENSTACK.user: myuser
  OPENSTACK.ssh_key_name: mykey
  OPENSTACK.ssh_key_file: '/etc/salt/hpcloud/mykey.pem'
  OPENSTACK.password: mypass

  # For Rackspace
  OPENSTACK.identity_url: 'https://identity.api.rackspacecloud.com/v2.0/tokens'
  OPENSTACK.compute_name: cloudServersOpenStack
  OPENSTACK.compute_region: DFW
  OPENSTACK.tenant: 5555555
  OPENSTACK.user: myuser
  OPENSTACK.password: mypass
  OPENSTACK.protocol: ipv4

It is important to note that currently, only password-based authentication is
provided through the Salt Cloud OpenStack module.

IBM has fewer things that need to be configured, but setting them up can be
tricky as well. An example might look like:

.. code-block:: yaml

  IBMSCE.user: myuser@mycorp.com
  IBMSCE.password: mypass
  IBMSCE.ssh_key_name: mykey
  IBMSCE.ssh_key_file: '/etc/salt/ibm/mykey.pem'
  IBMSCE.location: Raleigh

The location currently must be configured in order to create an instance, but
not to query the IBM cloud. This is important, because you need to use
salt-cloud --list-locations (with the other options already set) in order to
find the name of the location that you want to use.

OpenStack with Salt
===================

This isn't specifically another Salt Cloud feature, but it should be noted that
with the release of Salt 0.10.5, OpenStack is not only the first Cloud product,
but in fact the first piece of software explicitly supported by both Salt Cloud
(from a user perspective) and Salt itself (from an admin perspective).

Salt Cloud Logging
==================

Those who have tried to hack on Salt Cloud may have discovered a complete lack
of logging support. With this release, Salt Cloud has started to implement
the logging features already available in Salt. The default log location is
/var/log/salt/cloud (with a default level of warn), but it can be changed in
your cloud configuration file:

.. code-block:: yaml

  log_file: /var/log/salt/cloud
  log_level_logfile: debug

If you would like to change the default logging level for the command line, you
can also configure that in the same place:

.. code-block:: yaml

  log_level: debug

Check salt-cloud --help for a list of logging levels, which can also be
specified from the command line.
