DESCRIPTION
-----------
cdist is the frontend executable to the cdist configuration management.
It supports different subcommands as explained below.
It is written in Python so it requires :strong:`python`\ (1) to be installed.
It requires a minimal Python version 3.2.
GENERAL
-------
All commands accept the following options:
**-h, --help**
Show the help screen.
**-l LOGLEVEL, --log-level LOGLEVEL**
Set the specified verbosity level. The levels, in
order from the lowest to the highest, are: ERROR (-1),
WARNING (0), INFO (1), VERBOSE (2), DEBUG (3), TRACE (4
or higher). If used along with -v then -v increases
last set value and -l overwrites last set value.
**-q, --quiet**
Quiet mode: disables logging, including WARNING and ERROR.
**-v, --verbose**
Increase the verbosity level. Every instance of -v
increments the verbosity level by one. Its default
value is 0 which includes ERROR and WARNING levels.
The levels, in order from the lowest to the highest,
are: ERROR (-1), WARNING (0), INFO (1), VERBOSE (2),
DEBUG (3), TRACE (4 or higher). If used along with -l
then -l overwrites last set value and -v increases
last set value.
**-V, --version**
Show version and exit.
BANNER
------
Displays the cdist banner. Useful for printing
cdist posters - a must have for every office.
CONFIG/INSTALL
--------------
Configure/install one or more hosts.
Install command is currently in beta.
**-4, --force-ipv4**
Force to use IPv4 addresses only. No influence for
custom remote commands.

default hostdir is used. For more info on format see
:strong:`CACHE PATH PATTERN FORMAT` below.
**-c CONF_DIR, --conf-dir CONF_DIR**
Add a configuration directory. Can be specified multiple times.
If configuration directories contain conflicting types, explorers or
manifests, then the last one found is used.
**-f HOSTFILE, --file HOSTFILE**
Read specified file for a list of additional hosts to operate on
or if '-' is given, read stdin (one host per line).
If no host or host file is specified then, by default,
read hosts from stdin. For the file format see
:strong:`HOSTFILE FORMAT` below.
**-g CONFIG_FILE, --config-file CONFIG_FILE**
Use specified custom configuration file.
**-I INVENTORY_DIR, --inventory INVENTORY_DIR**
Use specified custom inventory directory. Inventory
directory is set up by the following rules: if cdist
configuration resolves this value then specified
directory is used, if HOME env var is set then
~/.cdit/inventory is used, otherwise distribution
inventory directory is used.
**-i MANIFEST, --initial-manifest MANIFEST**
Path to a cdist manifest or - to read from stdin.
**-j [JOBS], --jobs [JOBS]**
Operate in parallel in specified maximum number of
jobs. Global explorers, object prepare and object run

used by default.
**-R [{tar,tgz,tbz2,txz}], --use-archiving [{tar,tgz,tbz2,txz}]**
Operate by using archiving with compression where
appropriate. Supported values are: tar - tar archive,
tgz - gzip tar archive (the default), tbz2 - bzip2 tar
archive and txz - lzma tar archive. Currently in beta.

Directory to save cdist output in on the target host.
**-S, --disable-saving-output-streams**
Disable saving output streams.
**-s, --sequential**
Operate on multiple hosts sequentially (default).
**--remote-copy REMOTE_COPY**
Command to use for remote copy (should behave like scp).
**--remote-exec REMOTE_EXEC**
Command to use for remote execution (should behave like ssh).
**-t, --tag**
Host is specified by tag, not hostname/address; list
all hosts that contain any of specified tags.
Currently in beta.
HOSTFILE FORMAT
~~~~~~~~~~~~~~~
The HOSTFILE contains one host per line.
A comment is started with '#' and continues to the end of the line.
Any leading and trailing whitespace on a line is ignored.
Empty lines are ignored/skipped.
The Hostfile lines are processed as follows. First, all comments are
removed. Then all leading and trailing whitespace characters are stripped.
If such a line results in empty line it is ignored/skipped. Otherwise,
host string is used.
CACHE PATH PATTERN FORMAT
~~~~~~~~~~~~~~~~~~~~~~~~~
Cache path pattern specifies path for a cache directory subdirectory.
In the path, '%N' will be substituted by the target host, '%h' will
be substituted by the calculated host directory, '%P' will be substituted
by the current process id. All format codes that
:strong:`python` :strong:`datetime.strftime()` function supports, except
'%h', are supported. These date/time directives format cdist config/install
start time.
If empty pattern is specified then default calculated host directory
is used.
Calculated host directory is a hash of a host cdist operates on.
Resulting path is used to specify cache path subdirectory under which
current host cache data are saved.

FILES
-----
~/.cdist
Your personal cdist config directory. If exists it will be
automatically used.
~/.cdist/cache
Local cache directory.
~/.cdist/inventory
The home inventory directory. If ~/.cdist exists it will be used as
default inventory directory.
~/.cdist/preos
PreOS plugins directory, if existing.
cdist/conf
The distribution configuration directory. It contains official types and
explorers. This path is relative to cdist installation directory.
cdist/inventory
The distribution inventory directory.
This path is relative to cdist installation directory.
cdist/preos
The distribution PreOS plugins directory.
/etc/cdist.cfg
Global cdist configuration file, if exists.
~/.cdist.cfg or $XDG_CONFIG_HOME/cdist/cdist.cfg
Local cdist configuration file, if exists.
NOTES
-----
cdist detects if host is specified by IPv6 address. If so then remote_copy
command is executed with host address enclosed in square brackets
(see :strong:`scp`\ (1)).

CAVEATS
-------
When operating in parallel, either by operating in parallel for each host
(-p/--parallel) or by parallel jobs within a host (-j/--jobs), and depending
on target SSH server and its configuration you may encounter connection drops.
This is controlled with sshd :strong:`MaxStartups` configuration options.
You may also encounter session open refusal. This happens with ssh multiplexing
when you reach maximum number of open sessions permitted per network
connection. In this case ssh will disable multiplexing.
This limit is controlled with sshd :strong:`MaxSessions` configuration
options. For more details refer to :strong:`sshd_config`\ (5).
When requirements for the same object are defined in different manifests (see
example below), for example, in init manifest and in some other type manifest
and those requirements differ then dependency resolver cannot detect
dependencies correctly. This happens because cdist cannot prepare all objects first
and run all objects afterwards. Some object can depend on the result of type
explorer(s) and explorers are executed during object run. cdist will detect
such case and display a warning message. An example of such a case:
.. code-block:: sh
init manifest:
__a a
require="__e/e" __b b
require="__f/f" __c c
__e e
__f f
