Features
|
||||
========
|
||||
|
||||
But cdist ticks differently, here is the feature set that makes it unique:
|
||||
|
||||
Simplicity
|
||||
There is only one type to extend cdist called **type**
|
||||
|
||||
Design
|
||||
+ Type and core cleanly seperated
|
||||
+ Sticks completly to the KISS (keep it simple and stupid) paradigma
|
||||
+ Meaningful error messages - do not lose time debugging error messages
|
||||
+ Consistency in behaviour, naming and documentation
|
||||
+ No surprise factor: Only do what is obviously clear, no magic
|
||||
+ Define target state, do not focus on methods or scripts
|
||||
+ Push architecture: Instantly apply your changes
|
||||
|
||||
Small core
|
||||
cdist's core is very small - less code, less bugs
|
||||
|
||||
Fast development
|
||||
Focus on straightforwardness of type creation is a main development objective
|
||||
Batteries included: A lot of requirements can be solved using standard types
|
||||
|
||||
Modern Programming Language
|
||||
cdist is written in Python
|
||||
|
||||
Requirements, Scalability
|
||||
No central server needed, cdist operates in push mode and can be run from any computer
|
||||
|
||||
Requirements, Scalability, Upgrade
|
||||
cdist only needs to be updated on the master, not on the target hosts
|
||||
|
||||
Requirements, Security
|
||||
Uses well-know `SSH <http://www.openssh.com/>`_ as transport protocol
|
||||
|
||||
Requirements, Simplicity
|
||||
Requires only shell and SSH server on the target
|
||||
|
||||
UNIX
|
||||
Reuse of existing tools like cat, find, mv, ...
|
||||
|
||||
UNIX, familar environment, documentation
|
||||
Is available as manpages and HTML
|
||||
|
||||
UNIX, simplicity, familar environment

How to install cdist
|
||||
====================
|
||||
|
||||
Requirements
|
||||
-------------
|
||||
|
||||
Source Host
|
||||
~~~~~~~~~~~
|
||||
|
||||
This is the machine you use to configure the target hosts.
|
||||
|
||||
* /bin/sh: A posix like shell (for instance bash, dash, zsh)
|
||||
* Python >= 3.2
|
||||
* SSH client
|
||||
* sphinx (for building html docs and/or the manpages)
|
||||
|
||||
Target Hosts
|
||||
~~~~~~~~~~~~
|
||||
|
||||
* /bin/sh: A posix like shell (for instance bash, dash, zsh)
|
||||
* SSH server
|
||||
|
||||
Install cdist
|
||||
-------------
|
||||
|
||||
You can install cdist either from git or as a python package.
|
||||
|
||||
From git
|
||||
~~~~~~~~
|
||||
|
||||
Cloning cdist from git gives you the advantage of having
|
||||
a version control in place for development of your own stuff
|
||||
immediately.
|
||||
|
||||
To install cdist, execute the following commands:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
git clone https://github.com/ungleich/cdist.git
|
||||
cd cdist
|
||||
export PATH=$PATH:$(pwd -P)/bin
|
||||
|
||||
Available versions in git
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
* The active development takes place in the **master** branch
|
||||
* The released versions can be found in the tags
|
||||
|
||||
Other branches may be available for features or bugfixes, but they
|
||||
may vanish at any point. To select a specific branch use
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
# Generic code
|
||||
git checkout -b <localbranchname> origin/<branchname>
|
||||
|
||||
So for instance if you want to use and stay with version 4.1, you can use
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
git checkout -b 4.1 origin/4.1
|
||||
|
||||
Git mirrors
|
||||
^^^^^^^^^^^
|
||||
|
||||
If the main site is down, you can acquire cdist from one of the following sites:
|
||||
|
||||
* git://github.com/telmich/cdist.git `github <https://github.com/telmich/cdist>`_
|
||||
* git://git.code.sf.net/p/cdist/code `sourceforge <https://sourceforge.net/p/cdist/code>`_
|
||||
|
||||
Building and using manpages
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
If you want to build and use the manpages, run:
|
||||
|
||||
.. code-block:: sh
|
||||

and usually logs into the **target host** as the

How to update cdist
|
||||
===================
|
||||
|
||||
Update the git installation
|
||||
---------------------------
|
||||
|
||||
To upgrade cdist in the current branch use
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
git pull
|
||||
|
||||
# Also update the manpages
|
||||
./build man
|
||||
export MANPATH=$MANPATH:$(pwd -P)/doc/man
|
||||
|
||||
If you stay on a version branche (i.e. 1.0, 1.1., ...), nothing should break.
|
||||
The master branch on the other hand is the development branch and may not be
|
||||
working, break your setup or eat the tree in your garden.
|
||||
|
||||
Safely upgrading to new versions
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
To upgrade to **any** further cdist version, you can take the
|
||||
following procedure to do a safe upgrade:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
# Create new branch to try out the update
|
||||
git checkout -b upgrade_cdist
|
||||
|
||||
# Get latest cdist version in git database
|
||||
git fetch -v
|
||||
|
||||
# see what will happen on merge - replace
|
||||
# master with the branch you plan to merge
|
||||
git diff upgrade_cdist..origin/master
|
||||
|
||||
# Merge the new version
|
||||
git merge origin/master
|
||||
|
||||
Now you can ensure all custom types work with the new version.
|
||||
Assume that you need to go back to an older version during
|
||||
the migration/update, you can do so as follows:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
# commit changes
|
||||
git commit -m ...
|
||||
|
||||
# go back to original branch
|
||||
git checkout master
|
||||
|
||||
After that, you can go back and continue the upgrade:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
# git checkout upgrade_cdist
|
||||
|
||||
|
||||
Update the python package
|
||||
-------------------------
|
||||
|
||||
To upgrade to the lastet version do
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
pip install --upgrade cdist
|
||||
|
||||
General update instructions
|
||||
---------------------------
|
||||
|
||||
Updating from 3.0 to 3.1
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The type **\_\_ssh_authorized_keys** now also manages existing keys,
|
||||
not only the ones added by cdist.
|
||||
|
||||
Updating from 2.3 to 3.0
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The **changed** attribute of objects has been removed.
|
||||
Use `messaging </software/cdist/man/3.0.0/man7/cdist-messaging.html>`_ instead.
|
||||
|
||||
Updating from 2.2 to 2.3
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
No incompatiblities.
|
||||
|
||||
Updating from 2.1 to 2.2
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Starting with 2.2, the syntax for requiring a singleton type changed:
|
||||
Old format:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
require="__singleton_type/singleton" ...
|
||||
|
||||
New format:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
require="__singleton_type" ...
|
||||
|
||||
Internally the "singleton" object id was dropped to make life more easy.
|
||||
You can probably fix your configuration by running the following code
|
||||
snippet (currently untested, please report back if it works for you):
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
find ~/.cdist/* -type f -exec sed -i 's,/singleton,,' {} \;
|
||||
|
||||
Updating from 2.0 to 2.1
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Have a look at the update guide for [[2.0 to 2.1|2.0-to-2.1]].
|
||||
|
||||
* Type **\_\_package* and \_\_process** use --state **present** or **absent**.
|
||||
The states **removed/installed** and **stopped/running** have been removed.
|
||||
Support for the new states is already present in 2.0.
|
||||
* Type **\_\_directory**: Parameter --parents and --recursive are now boolean
|
||||
The old "yes/no" values need to be removed.
|
||||
* Type **\_\_rvm_ruby**: Parameter --default is now boolean
|
||||
The old "yes/no" values need to be removed.
|
||||
* Type **\_\_rvm_gemset**: Parameter --default is now boolean
|
||||
The old "yes/no" values need to be removed.
|
||||
* Type **\_\_addifnosuchline** and **\_\_removeline** have been replaced by **\_\_line**
|
||||
* The **conf** directory is now located at **cdist/conf**.
|
||||
You need to migrate your types, explorers and manifests
|
||||
manually to the new location.
|
||||
* Replace the variable **\_\_self** by **\_\_object_name**
|
||||
Support for the variable **\_\_object_name** is already present in 2.0.
|
||||
* The types **\_\_autofs**, **\_\_autofs_map** and **\_\_autofs_reload** have been removed
|
||||
(no maintainer, no users)
|
||||
* Type **\_\_user**: Parameter --groups removed (use the new \_\_user_groups type)
|
||||
* Type **\_\_ssh_authorized_key** has been replaced by more flexible type
|
||||
**\_\_ssh_authorized_keys**
|
||||
|
||||
Updating from 1.7 to 2.0
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
* Ensure python (>= 3.2) is installed on the source host
|
||||
* Use "cdist config host" instead of "cdist-deploy-to host"
|
||||
* Use "cdist config -p host1 host2" instead of "cdist-mass-deploy"
|
||||
* Use "cdist banner" for fun
|
||||
* Use **\_\_object_name** instead of **\_\_self** in manifests
|
||||
|
||||
Updating from 1.6 to 1.7
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
* If you used the global explorer **hardware_type**, you need to change
|
||||
your code to use **machine** instead.
|
||||
|
||||
Updating from 1.5 to 1.6
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
* If you used **\_\_package_apt --preseed**, you need to use the new
|
||||
type **\_\_debconf_set_selections** instead.
|
||||
* The **\_\_package** types accepted either --state deinstalled or
|

~~~~~~~~~~~~~~~~~~~~~~~~

No incompatiblities.

Rename **gencode** of every type to **gencode-remote**.
|

Updating from 1.1 to 1.2

~~~~~~~~~~~~~~~~~~~~~~~~
|

|

No incompatiblities.
|

|

Updating from 1.0 to 1.1
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
In 1.1 the type **\_\_file** was split into **\_\_directory**, **\_\_file** and
|
||||
**\_\_link**. The parameter **--type** was removed from **\_\_file**. Thus you
|
||||
need to replace **\_\_file** calls in your manifests:
|
||||
|
||||
* Remove --type from all \_\_file calls
|
||||
* If type was symlink, use \_\_link and --type symbolic
|
||||
* If type was directory, use \_\_directory

Why should I use cdist?
|
||||
=======================
|
||||
|
||||
There are several motivations to use cdist, these
|
||||
are probably the most popular ones.
|
||||
|
||||
Known language
|
||||
--------------
|
||||
|
||||
Cdist is being configured in
|
||||
`shell script <https://en.wikipedia.org/wiki/Shell_script>`_.
|
||||
Shell script is used by UNIX system engineers for decades.
|
||||
So when cdist is introduced, your staff does not need to learn a new
|
||||
`DSL <https://en.wikipedia.org/wiki/Domain-specific_language>`_
|
||||
or programming language.
|
||||
|
||||
Powerful language
|
||||
-----------------
|
||||
|
||||
Not only is shell scripting widely known by system engineers,
|
||||
but it is also a very powerful language. Here are some features
|
||||
which make daily work easy:
|
||||
|
||||
* Configuration can react dynamicly on explored values
|
||||
* High level string manipulation (using sed, awk, grep)
|
||||
* Conditional support (**if, case**)
|
||||
* Loop support (**for, while**)
|
||||
* Support for dependencies between cdist types
|
||||
|
||||
More than shell scripting
|
||||
-------------------------
|
||||
|
||||
If you compare regular shell scripting with cdist, there is one major
|
||||
difference: When using cdist types,
|
||||
the results are
|
||||
`idempotent <https://en.wikipedia.org/wiki/Idempotence>`_.
|
||||
In practise that means it does not matter in which order you
|
||||
call cdist types, the result is always the same.
|
||||
|
||||
Zero dependency configuration management
|
||||
----------------------------------------
|
||||
|
||||
Cdist requires very litte on a target system. Even better,
|
||||
in almost all cases all dependencies are usually fulfilled.
|
||||
Cdist does not require an agent or a high level programming
|
||||
languages on the target host: it will run on any host that
|
||||
has a **ssh server running** and a posix compatible shell
|
||||
(**/bin/sh**). Compared to other configuration management systems,
|
||||
it does not require to open up an additional port.
|
||||
|
||||
Push based distribution
|
||||
-----------------------
|
||||
|
||||
Cdist uses the push based model for configuration. In this
|
||||
scenario, one (or more) computers connect the target hosts
|
||||
and apply the configuration. That way the source host has
|
||||
very little requirements: Cdist can even run on a sysadmin
|
||||
notebook that is loosely connected to the network and has
|
||||
limited amount of resources.
|
||||
|
||||
Furthermore, from a security point of view, only one machine
|
||||
needs access to the target hosts. No target hosts will ever
|
||||
need to connect back to the source host, which contains the
|
||||
full configuration.
|
||||
|
||||
Highly scalable
|
||||
---------------
|
||||
|
||||
If at some point you manage more hosts than can be handled from
|
||||
a single source host, you can simply add more resources: Either
|
||||
add more cores to one host or add hosts.
|
||||
Cdist will utilise the given resources in parallel.
