Fabric is an incredible tool to automate administration of remote machines. As Fabric's functions are rather low-level, you'll probably quickly see a need for more high-level functions such as add/remove users and groups, install/upgrade packages, etc.
Cuisine is a small set of functions that sit on top of Fabric, to abstract common administration operations such as file/dir operations, user/group creation, package install/upgrade, making it easier to write portable administration and deployment scripts.
Cuisine's features are:
- Small, easy to read, a single file API: object_operation() e.g.
dir_exists(location) tells if there is a remote directory at the
- Covers file/dir operations, user/group operations, package operations
- Text processing and template functions
- All functions are lazy: they will actually only do things when the
change is required.
Cuisine is on PyPI so you can either use
easy_install -U cuisine
pip install cuisine to install it. Otherwise, you can download
the source from
GitHub <http://github.com/sebastien/cuisine>_ and
python setup.py install.
Cuisine requires Python 2.7, and has not been tested with Python 3 yet.
How to get started
Open up a python shell and type:
Cuisine is designed to be a flat-file module, where all functions are prefixed
by the type of functionality they offer (e.g.,
file for file operations,
user for user operations). The available groups are:
`text_*` Text-processing functions `file_*` File operations `dir_*` Directory operations `package_*` Package management operations `command_*` Shell commands availability `user_*` User creation commands `group*` Group creation commands `mode_*` Configures cuisine's behaviour within the current session. `select_*` Selects a specific option, such as package back-end (`apt`, `yum`, `zypper`, or `pacman`)
If you're using an interactive Python shell such as
IPython <http://ipython.org/>_ you can easily browse the available
functions by using tab-completion.
In : cuisine.file_ cuisine.file_append cuisine.file_is_file cuisine.file_unlink cuisine.file_attribs cuisine.file_is_link cuisine.file_update cuisine.file_attribs_get cuisine.file_link cuisine.file_upload cuisine.file_ensure cuisine.file_local_read cuisine.file_write cuisine.file_exists cuisine.file_read cuisine.file_is_dir cuisine.file_sha256
As the functions are prefixed by they type of functionality, it is very
easy to get started using an interactive shell.
If you would like to use cuisine without using a
fabfile, you can call the
import cuisine cuisine.mode_local() print cuisine.run("echo Hello")
alternatively, you can also directly connect to a server
import cuisine cuisine.connect("my.server.com") print cuisine.run("echo Hello")
If you want to use cuisine within a
fabfile, simply create a
with the following content:
from cuisine import * def setup(): group_ensure("remote_admin") user_ensure("admin") group_user_ensure("remote_admin", "admin")
If you are encoutering problems, please check the following:
- The [email protected] is running an SH-compatible shell (sh, dash, bash, zsh should work)
- The system has
sha1sumcommands in addition
to the basic UNIX ones.
If you still have a problem, simply file a bug report
Right now, cuisine is tested on Ubuntu. Some contributors use it on RHEL
and CentOS. If you use on a different system, let us know if it works!
Contributing specific implementations
Cuisine was originally developed as a Debian/Ubuntu-centric tool, but can
easily be adapted to other distributions or Unix flavor, the only caveat being
that the shell is expected to be bash-compatible.
If you want to implement a specific variant of some functions for a specific
platform, you should do the following:
- Open the
cuisine.pysource and look for the definition of the function
that you would like to specialize.
- If the function is decorated by '@dispatch', it means it already supports
specific back-ends (see
package_*functions), and you can proceed
to the next step. Otherwise, you can either file a ticket on Github
or read the source and mimic what we've done for
- Create a specific version of the decorated function by creating a new
function with the same name, suffixed by your specific backend name. For
instance, if you'd like to create a
you would need to create a function
package_ensure_yumwith the same
- Once you've created your specific functions, make sure that you have
select_*matching your function group. For the
this would be
- Look for the
supportedvariable in the
select_*and add your backend
suffix to it (in our example, this would be
To use a specific backend implementation of a set of features, use the
# To use the 'apt' backend cuisine.select_package("apt") # To see the available backends print cuisine.select_package()
