SaltStack runners模块分析之pillar模块

/usr/lib/python2.6/site-packages/salt/runners/pillar.py
pillar runner模块提供一些在Master端与Pillar编译器交互的函数

返回指定minion的pillar的编译top数据，如果没有指定minion，就使用第一个找到的minion

def show_top(minion=None, saltenv='base'):
'''
Returns the compiled top data for pillar for a specific minion.  If no
minion is specified, we use the first minion we find.

CLI Example:

.. code-block:: bash

salt-run pillar.show_top
'''
id_, grains, _ = salt.utils.minions.get_minion_data(minion, __opts__)
pillar = salt.pillar.Pillar(
__opts__,
grains,
id_,
saltenv)

top, errors = pillar.get_top()

if errors:
salt.output.display_output(errors, 'nested', __opts__)
return errors

salt.output.display_output(top, 'nested', __opts__)
return top

$ sudo salt-run pillar.show_top  'jialebi-qa-server'
base:
----------
*:
- packages
- services

def show_pillar(minion='*', **kwargs):
'''
Returns the compiled pillar either of a specific minion
or just the global available pillars. I assume that no minion
is using the id ``*``.

CLI Example:

shows minion specific pillar:

.. code-block:: bash

salt-run pillar.show_pillar 'www.example.com'

shows global pillar:

.. code-block:: bash

salt-run pillar.show_pillar

shows global pillar for 'dev' pillar environment:

.. code-block:: bash

salt-run pillar.show_pillar 'saltenv=dev'

API Example:

.. code-block:: python

import salt.config
import salt.runner
opts = salt.config.master_config('/etc/salt/master')
runner = salt.runner.RunnerClient(opts)
pillar = runner.cmd('pillar.show_pillar', [])
print pillar
'''

saltenv = 'base'
id_, grains, _ = salt.utils.minions.get_minion_data(minion, __opts__)
if grains is None:
grains = {'fqdn': minion}

for key in kwargs:
if key == 'saltenv':
saltenv = kwargs[key]
else:
grains[key] = kwargs[key]

pillar = salt.pillar.Pillar(
__opts__,
grains,
id_,
saltenv)

compiled_pillar = pillar.compile_pillar()
salt.output.display_output(compiled_pillar, 'nested', __opts__)
return compiled_pillar
