This completes the documentation audit begun in cf365f7, using proper
backticks and :strong: tags to emphasize text, converting groups of
shell commands to bash code-block sections, etc. This also replaces the
use of \* with the easier-to-grok '*', which will hopefully reduce
confusion among new users.

Order your minions around
|
|
=========================
|
|
|
|
Now that you have a :term:`master` and at least one :term:`minion`
|
|
communicating with each other you can perform commands on the minion via the
|
|
:command:`salt` command. Salt calls are comprised of three main components:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt '<target>' <function> [arguments]
|
|
|
|
.. seealso:: :doc:`salt manpage </ref/cli/salt>`
|
|
|
|
target
|
|
------
|
|
|
|
The target component allows you to filter which minions should run the
|
|
following function. The default filter is a glob on the minion id. For example:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt '*' test.ping
|
|
salt '*.example.org' test.ping
|
|
|
|
Targets can be based on minion system information using the Grains system:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt -G 'os:Ubuntu' test.ping
|
|
|
|
.. seealso:: :doc:`Grains system </topics/targeting/grains>`
|
|
|
|
Targets can be filtered by regular expression:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt -E 'virtmach[0-9]' test.ping
|
|
|
|
Targets can be explicitly specified in a list:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt -L 'foo,bar,baz,quo' test.ping
|
|
|
|
Or Multiple target types can be combined in one command:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt -C 'G@os:Ubuntu and webser* or E@database.*' test.ping
|
|
|
|
|
|
function
|
|
--------
|
|
|
|
A function is some functionality provided by a module. Salt ships with a large
|
|
collection of available functions. List all available functions on your
|
|
minions:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt '*' sys.doc
|
|
|
|
Here are some examples:
|
|
|
|
Show all currently available minions:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt '*' test.ping
|
|
|
|
Run an arbitrary shell command:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt '*' cmd.run 'uname -a'
|
|
|
|
.. seealso:: :doc:`the full list of modules </ref/modules/index>`
|
|
|
|
arguments
|
|
---------
|
|
|
|
Space-delimited arguments to the function:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt '*' cmd.exec_code python 'import sys; print sys.version'
|
|
|
|
Optional, keyword arguments are also supported:
|
|
|
|
.. code-block:: bash
|
|
|
|
salt '*' pip.install salt timeout=5 upgrade=True
|
|
|
|
They are always in the form of ``kwarg=argument``.
