Automatic Updates / Frozen Deployments
|
|
======================================
|
|
|
|
.. versionadded:: 0.10.3.d
|
|
|
|
Salt has support for the
|
|
`Esky <https://github.com/cloudmatrix/esky>`_ application freezing and update
|
|
tool. This tool allows one to build a complete zipfile out of the salt scripts
|
|
and all their dependencies - including shared objects / DLLs.
|
|
|
|
Getting Started
|
|
===============
|
|
|
|
To build frozen applications, you'll need a suitable build environment for each
|
|
of your platforms. You should probably set up a virtualenv in order to limit
|
|
the scope of Q/A.
|
|
|
|
This process does work on Windows. Follow the directions at
|
|
`<https://github.com/saltstack/salt-windows-install>`_ for details on
|
|
installing Salt in Windows. Only the 32-bit Python and dependencies have been
|
|
tested, but they have been tested on 64-bit Windows.
|
|
|
|
You will need to install ``esky`` and ``bbfreeze`` from Pypi in order to enable
|
|
the ``bdist_esky`` command in ``setup.py``.
|
|
|
|
Building and Freezing
|
|
=====================
|
|
|
|
Once you have your tools installed and the environment configured, you can then
|
|
``python setup.py bdist`` to get the eggs prepared. After that is done, run
|
|
``python setup.py bdist_esky`` to have Esky traverse the module tree and pack
|
|
all the scripts up into a redistributable. There will be an appropriately
|
|
versioned ``salt-VERSION.zip`` in ``dist/`` if everything went smoothly.
|
|
|
|
Windows
|
|
-------
|
|
You will need to add ``C:\Python27\lib\site-packages\zmq`` to your PATH
|
|
variable. This helps bbfreeze find the zmq dll so it can pack it up.
|
|
|
|
Using the Frozen Build
|
|
======================
|
|
|
|
Unpack the zip file in your desired install location. Scripts like
|
|
``salt-minion`` and ``salt-call`` will be in the root of the zip file. The
|
|
associated libraries and bootstrapping will be in the directories at the same
|
|
level. (Check the `Esky <https://github.com/cloudmatrix/esky>`_ documentation
|
|
for more information)
|
|
|
|
To support updating your minions in the wild, put your builds on a web server
|
|
that your minions can reach. :py:func:`salt.modules.saltutil.update` will
|
|
trigger an update and (optionally) a restart of the minion service under the
|
|
new version.

Gotchas
|
|
=======
|
|
|
|
My Windows minion isn't responding
|
|
----------------------------------
|
|
The process dispatch on Windows is slower than it is on \*nix. You may need to
|
|
add '-t 15' to your salt calls to give them plenty of time to return.
|
|
|
|
Windows and the Visual Studio Redist
|
|
------------------------------------
|
|
You will need to install the Visual C++ 2008 32-bit redistributable on all
|
|
Windows minions. Esky has an option to pack the library into the zipfile,
|
|
but OpenSSL does not seem to acknowledge the new location. If you get a
|
|
``no OPENSSL_Applink`` error on the console when trying to start your
|
|
frozen minion, you have forgotten to install the redistributable.
|
|
|
|
Mixed Linux environments and Yum
|
|
--------------------------------
|
|
The Yum Python module doesn't appear to be available on any of the standard
|
|
Python package mirrors. If you need to support RHEL/CentOS systems, you
|
|
should build on that platform to support all your Linux nodes. Also remember
|
|
to build your virtualenv with ``--system-site-packages`` so that the
|
|
``yum`` module is included.
|
|
|
|
Automatic (Python) module discovery
|
|
-----------------------------------
|
|
Automatic (Python) module discovery does not work with the late-loaded scheme that
|
|
Salt uses for (Salt) modules. You will need to explicitly add any
|
|
misbehaving modules to the ``freezer_includes`` in Salt's ``setup.py``.
|
|
Always check the zipped application to make sure that the necessary modules
|
|
were included.
