salt-api 0.8.4
|
|
==============
|
|
|
|
:program:`salt-api` 0.8.4 sees a number of new features and feature
|
|
enhancements in the :py:mod:`rest_cherrypy <salt.netapi.rest_cherrypy.app>`
|
|
netapi module.
|
|
|
|
Work to merge :program:`salt-api` into the main Salt distribution continues and
|
|
it is likely to be included in Salt's 2014.7.0 release.
|
|
|
|
:py:mod:`rest_cherrypy <salt.netapi.rest_cherrypy.app>` changes
|

==================================================================

|
Web hooks
|
|
---------
|
|
|
|
This release adds a :py:class:`new URL /hook
|
|
<salt.netapi.rest_cherrypy.app.Webhook>` that allows salt-api to serve as a
|
|
generic web hook interface for Salt. POST requests to the URL trigger events on
|
|
Salt's event bus.
|
|
|
|
External services like Amazon SNS, Travis CI, GitHub, etc can easily send
|
|
signals through Salt's Reactor.
|
|
|
|
The following HTTP call will trigger the following Salt event.
|
|
|
|
.. code-block:: bash
|
|
|
|
% curl -sS http://localhost:8000/hook/some/tag \
|
|
-d some='Data!'
|
|
|
|
Event tag: ``salt/netapi/hook/some/tag``. Event data:
|
|
|
|
.. code-block:: json
|
|
|
|
{
|
|
"_stamp": "2014-04-04T12:14:54.389614",
|
|
"post": {
|
|
"some": "Data!"
|
|
},
|
|
"headers": {
|
|
"Content-Type": "application/x-www-form-urlencoded",
|
|
"Host": "localhost:8000",
|
|
"User-Agent": "curl/7.32.0",
|
|
"Accept": "*/*",
|
|
"Content-Length": "10",
|
|
"Remote-Addr": "127.0.0.1"
|
|
}
|
|
}
|
|
|
|
Batch mode
|
|
----------
|
|
|
|
The :py:meth:`~salt.netapi.NetapiClient.local_batch` client exposes Salt's batch mode
|
|
for executing commands on incremental subsets of minions.
|
|
|
|
Tests!
|
|
------
|
|
|
|
We have added the necessary framework for testing the rest_cherrypy module and
|
|
this release includes a number of both unit and integration tests. The suite
|
|
can be run with the following command:
|
|
|
|
.. code-block:: bash
|
|
|
|
python -m unittest discover -v
|
|
|
|
CherryPy server stats and configuration
|
|
---------------------------------------
|
|
|
|
A number of settings have been added to better configure the performance of the
|
|
CherryPy web server. In addition, a :py:class:`new URL /stats
|
|
<salt.netapi.rest_cherrypy.app.Stats>` has been added to expose metrics on
|
|
the health of the CherryPy web server.
|
|
|
|
Improvements for running with external WSGI servers
|
|
---------------------------------------------------
|
|
|
|
Running the ``rest_cherrypy`` module via a WSGI-capable server such as Apache
|
|
or Nginx can be tricky since the user the server is running as must have
|
|
permission to access the running Salt system. This release eases some of those
|
|
restrictions by accessing Salt's key interface through the external auth
|
|
system. Read access to the Salt configuration is required for the user the
|
|
server is running as and everything else should go through external auth.
|
|
|
|
More information in the jobs URLs
|
|
---------------------------------
|
|
|
|
The output for the :py:class:`/jobs/<jid> URLs
|
|
<salt.netapi.rest_cherrypy.app.Jobs>` has been augmented with more
|
|
information about the job such as which minions are expected to return for that
|
|
job. This same output will be added to the other salt-api URLs in the next
|
|
release.
|
|
|
|
Improvements to the Server Sent Events stream
|
|
---------------------------------------------
|
|
|
|
Event tags have been added to :py:class:`the HTTP event stream
|
|
<salt.netapi.rest_cherrypy.app.Event>` as SSE tags which allows JavaScript
|
|
or other consumers to more easily match on certain tags without having to
|
|
inspect the whole event.
