Salt 0.10.2 Release Notes
|
|
=========================
|
|
|
|
:release: 2012-07-30
|
|
|
|
0.10.2 is out! This release comes with enhancements to the pillar interface,
|
|
cleaner ways to access the salt-call capabilities in the API, minion data
|
|
caching and the event system has been added to salt minions.
|
|
|
|
There have also been updates to the ZeroMQ functions, many more tests
|
|
(thanks to sponsors, the code sprint and many contributors) and a swath
|
|
of bug fixes.
|
|
|
|
Major Features
|
|
==============
|
|
|
|
Ext Pillar Modules
|
|
------------------
|
|
|
|
The ranks of available Salt modules directories sees a new member in 0.10.2.
|
|
With the popularity of pillar a higher demand has arisen for ``ext_pillar``
|
|
interfaces to be more like regular Salt module additions. Now ext_pillar
|
|
interfaces can be added in the same way as other modules, just drop it into
|
|
the pillar directory in the salt source.
|
|
|
|
Minion Events
|
|
-------------
|
|
|
|
In 0.10.0 an event system was added to the Salt master. 0.10.2 adds the event
|
|
system to the minions as well. Now event can be published on a local minion
|
|
as well.
|
|
|
|
The minions can also send events back up to the master. This means that Salt is
|
|
able to communicate individual events from the minions back up to the Master
|
|
which are not associated with command.
|
|
|
|
Minion Data Caching
|
|
-------------------
|
|
|
|
When pillar was introduced the landscape for available data was greatly
|
|
enhanced. The minion's began sending grain data back to the master on a
|
|
regular basis.
|
|
|
|
The new config option on the master called ``minion_data_cache`` instructs the
|
|
Salt master to maintain a cache of the minion's grains and pillar data in the
|
|
cachedir. This option is turned off by default to avoid hitting the disk more,
|
|
but when enabled the cache is used to make grain matching from the salt command
|
|
more powerful, since the minions that will match can be predetermined.
|
|
|
|
Backup Files
|
|
------------
|
|
|
|
By default all files replaced by the file.managed and file.recurse states we
|
|
simply deleted. 0.10.2 adds a new option. By setting the backup option to
|
|
``minion`` the files are backed up before they are replaced.
|
|
|
|
The backed up files are located in the cachedir under the file_backup
|
|
directory. On a default system this will be at:
|
|
``/var/cache/salt/file_backup``
|
|
|
|
Configuration files
|
|
-------------------
|
|
|
|
``salt-master`` and ``salt-minion`` automatically load additional configuration
|
|
files from ``master.d/*.conf`` respective ``minion.d/*.conf`` where
|
|
``master.d``/``minion.d`` is a directory in the same directory as the main
|
|
configuration file.
|
|
|
|
Salt Key Verification
|
|
---------------------
|
|
|
|
A number of users complained that they had inadvertently deleted the wrong salt
|
|
authentication keys. 0.10.2 now displays what keys are going to be deleted
|
|
and verifies that they are the keys that are intended for deletion.
|
|
|
|
Key auto-signing
|
|
----------------
|
|
|
|
If ``autosign_file`` is specified in the configuration file incoming keys
|
|
will be compared to the list of keynames in ``autosign_file``. Regular
|
|
expressions as well as globbing is supported.
|
|
|
|
The file must only be writable by the user otherwise the file will be
|
|
ignored. To relax the permission and allow group write access set the
|
|
``permissive_pki_access`` option.
|
|
|
