Salt 0.15.0 Release Notes
|
|
=========================
|
|
|
|
The many new features of Salt 0.15.0 have arrived! Salt 0.15.0 comes with many
|
|
smaller features and a few larger ones.
|
|
|
|
These features range from better debugging tools to the new Salt Mine system.
|
|
|
|
Major Features
|
|
==============
|
|
|
|
The Salt Mine
|
|
-------------
|
|
|
|
First there was the peer system, allowing for commands to be executed from a
|
|
minion to other minions to gather data live. Then there was the external job
|
|
cache for storing and accessing long term data. Now the middle ground is being
|
|
filled in with the Salt Mine. The Salt Mine is a system used to execute
|
|
functions on a regular basis on minions and then store only the most recent
|
|
data from the functions on the master, then the data is looked up via targets.
|
|
|
|
The mine caches data that is public to all minions, so when a minion posts
|
|
data to the mine all other minions can see it.
|
|
|
|
IPV6 Support
|
|
------------
|
|
|
|
0.13.0 saw the addition of initial IPV6 support but errors were encountered and
|
|
it needed to be stripped out. This time the code covers more cases and must be
|
|
explicitly enabled. But the support is much more extensive than before.
|
|
|
|
Copy Files From Minions to the Master
|
|
-------------------------------------
|
|
|
|
Minions have long been able to copy files down from the master file server, but
|
|
until now files could not be easily copied from the minion up to the master.
|
|
|
|
A new function called ``cp.push`` can push files from the minions up to the
|
|
master server. The uploaded files are then cached on the master in the master
|
|
cachedir for each minion.
|
|
|
|
Better Template Debugging
|
|
-------------------------
|
|
|
|
Template errors have long been a burden when writing states and pillar. 0.15.0
|
|
will now send the compiled template data to the debug log, this makes tracking
|
|
down the intermittent stage templates much easier. So running state.sls or
|
|
state.highstate with `-l debug` will now print out the rendered templates in
|
|
the debug information.
|
|
|
|
State Event Firing
|
|
------------------
|
|
|
|
The state system is now more closely tied to the master's event bus. Now when
|
|
a state fails the failure will be fired on the master event bus so that the
|
|
reactor can respond to it.
|
|
|
|
Major Syndic Updates
|
|
--------------------
|
|
|
|
The Syndic system has been basically re-written. Now it runs in a completely
|
|
asynchronous way and functions primarily as an event broker. This means that
|
|
the events fired on the syndic are now pushed up to the higher level master
|
|
instead of the old method used which waited for the client libraries to
|
|
return.
|
|
|
|
This makes the syndic much more accurate and powerful, it also means that
|
|
all events fired on the syndic master make it up the pipe as well making a
|
|
reactor on the higher level master able to react to minions further
|
|
downstream.
|
|
|
|
Peer System Updates
|
|
-------------------
|
|
|
|
The Peer System has been updated to run using the client libraries instead
|
|
of firing directly over the publish bus. This makes the peer system much more
|
|
consistent and reliable.
|
|
|
|
Minion Key Revocation
|
|
---------------------
|
|
|
|
In the past when a minion was decommissioned the key needed to be manually
|
|
deleted on the master, but now a function on the minion can be used to revoke
|
|
the calling minion's key:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ salt-call saltutil.revoke_auth
|
|
|
|
Function Return Codes
|
|
---------------------
|
|
|
|
Functions can now be assigned numeric return codes to determine if the function
|
|
executed successfully. While not all functions have been given return codes,
|
|
many have and it is an ongoing effort to fill out all functions that might
|
|
return a non-zero return code.
|
|
|
|
Functions in Overstate
|
|
----------------------
|
|
|
|
The overstate system was originally created to just manage the execution of
|
|
states, but with the addition of return codes to functions, requisite logic can
|
|
now be used with respect to the overstate. This means that an overstate stage
|
|
can now run single functions instead of just state executions.
|
|
|
|
Pillar Error Reporting
|
|
----------------------
|
|
|
|
Previously if errors surfaced in pillar, then the pillar would consist of only
|
|
an empty dict. Now all data that was successfully rendered stays in pillar and
|
|
the render error is also made available. If errors are found in the pillar,
|
|
states will refuse to run.
|
|
|
|
Using Cached State Data
|
|
-----------------------
|
|
|
|
Sometimes states are executed purely to maintain a specific state rather than
|
|
to update states with new configs. This is grounds for the new cached state
|
|
system. By adding `cache=True` to a state call the state will not be generated
|
|
fresh from the master but the last state data to be generated will be used.
|
|
If no previous state data is available then fresh data will be generated.
|
|
|
|
Monitoring States
|
|
-----------------
|
|
|
|
The new monitoring states system has been started. This is very young but
|
|
allows for states to be used to configure monitoring routines. So far only one
|
|
monitoring state is available, the ``disk.status`` state. As more capabilities
|
|
are added to Salt UI the monitoring capabilities of Salt will continue to be
|
|
expanded.
