Due to a change in master to minion communication, 2014.1.0 minions are not compatible with older-version masters. Please upgrade masters first. More info on backwards-compatibility policy here, under the "Upgrading Salt" subheading.
A change in the grammar in the state compiler makes
requisites illegal syntax. Its use is replaced simply with the word
module. In other words you will need to change requisites like this:
require: module.run: some_module_name
require: module: some_module_name
This is a breaking change. We apologize for the inconvenience, we needed to do this to remove some ambiguity in parsing requisites.
The 2014.1.0 release of Salt is a major release which not only increases stability but also brings new capabilities in virtualization, cloud integration, and more. This release brings a great focus on the expansion of testing making roughly double the coverage in the Salt tests, and comes with many new features.
2014.1.0 is the first release to follow the new date-based release naming system. See the version numbers page for more details.
Salt Cloud is a tool for provisioning salted minions across various cloud providers. Prior to this release, Salt Cloud was a separate project but this marks its full integration with the Salt distribution. A Getting Started guide and additional documentation for Salt Cloud can be found here:
Alongside Salt Cloud comes new support for the Google Compute Engine. Salt Stack can now deploy and control GCE virtual machines and the application stacks that they run.
For more information on Salt Stack and GCE, please see this blog post.
Documentation for Salt and GCE can be found here.
Salt Virt is a cloud controller that supports virtual machine deployment, inspection, migration, and integration with many aspects of Salt.
Salt Virt has undergone a major overhaul with this release and now supports many more features and includes a number of critical improvements.
Salt continues to increase its unit/regression test coverage. This release includes over 300 new tests.
BSD package management has been entirely rewritten. FreeBSD 9 and older now default to using pkg_add, while FreeBSD 10 and newer will use pkgng. FreeBSD 9 can be forced to use pkgng, however, by specifying the following option in the minion config file:
providers: pkg: pkgng
module now have IPv6 support. A new parameter
been added to the states and execution functions, to distinguish between IPv4
and IPv6. The default value for this parameter is
will use ip6tables to manage firewall rules.
Several performance improvements have been made to the
backend. Additionally, file states can now use any
any SHA1 commit hash as a fileserver environment:
/etc/httpd/httpd.conf: file.managed: - source: salt://webserver/files/httpd.conf - saltenv: 45af879
This applies to the functions in the
cp module as
salt '*' cp.get_file salt://readme.txt /tmp/readme.txt saltenv=45af879
This new fileserver backend allows files which have been pushed from the minion
to the master (using
cp.push) to be served up
from the salt fileserver. The path for these files takes the following format:
minion-id is the id of the "source" minion, the one from which the files
were pushed to the master.
/path/to/file is the full path of the file.
The MinionFS Walkthrough contains a more thorough example of how to use this backend.
To distinguish between fileserver environments and execution functions which
deal with environment variables, fileserver environments are now specified
env will continue to work, but is
deprecated and will be removed in a future release.
A caching layer has been added to the Grains system, which can help speed up
minion startup. Disabled by default, it can be enabled by setting the minion
grains_cache: True # Seconds before grains cache is considered to be stale. grains_cache_expiration: 300
If set to
True, the grains loader will read from/write to a
msgpack-serialized file containing the grains data.
Additional command-line parameters have been added to salt-call, mainly for testing purposes:
--skip-grainswill completely bypass the grains loader when salt-call is invoked.
--refresh-grains-cachewill force the grains loader to bypass the grains cache and refresh the grains, writing a new grains cache file.
When using the
cmd module, either on the CLI or
when developing Salt execution modules, a new keyword argument
output_loglevel allows for greater control over how (or even if) the
command and its output are logged. For example:
salt '*' cmd.run 'tail /var/log/messages' output_loglevel=debug
The package management modules (
yumpkg, etc.) have been updated to
log the copious output generated from these commands at loglevel
To keep a command from being logged,
output_loglevel=quiet can be used.
Prior to this release, this could be done using
argument is still supported, but will be removed in a future Salt release.
Sometimes the subprocess module is not good enough, and, in fact, not even
askpass is. This virtual terminal is still in it's infant childhood, needs
quite some love, and was originally created to replace
askpass, but, while
developing it, it immediately proved that it could do so much more. It's
currently used by salt-cloud when bootstrapping salt on clouds which require
the use of a password.
Initial basic support for Proxy Minions is in this release. Documentation can be found here.
Proxy minions are a developing feature in Salt that enables control of devices that cannot run a minion. Examples include network gear like switches and routers that run a proprietary OS but offer an API, or "dumb" devices that just don't have the horsepower or ability to handle a Python VM.
Proxy minions can be difficult to write, so a simple REST-based example proxy is included. A Python bottle-based webserver can be found at https://github.com/cro/salt-proxy-rest as an endpoint for this proxy.
This is an ALPHA-quality feature. There are a number of issues with it currently, mostly centering around process control, logging, and inability to work in a masterless configuration.
Below are many of the fixes that were implemented in salt during the release candidate phase.
ZMQError: Operation cannot be accomplished in current stateerrors (issue 6306)
archivestate to work with
salt-run -dto limit results to specific runner or function (issue 9975)
