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 python(1) to be installed.  It requires  a  minimal
       Python version 3.5.

GENERAL

       All commands accept the following options:

       -h, --help
              Show the help screen.

       --colors WHEN
              Colorize  cdist's output. If enabled, cdist will use different colors for different
              log levels.   WHEN  recognizes  the  values  'always',  'never',  and  'auto'  (the
              default).

              If  the  value  is  'auto', colored output is enabled if stdout is a TTY unless the
              NO_COLOR (https://no-color.org/) environment variable is defined.

       -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.

       -6, --force-ipv6
              Force to use IPv6 addresses only. No influence for custom remote commands.

       -A, --all-tagged
              Use all hosts present in tags db. Currently in beta.

       -a, --all
              List hosts that have all specified tags, if -t/--tag is specified.

       -b, --beta
              Enable beta functionality.

       -C CACHE_PATH_PATTERN, --cache-path-pattern CACHE_PATH_PATTERN
              Specify custom cache path pattern. If it is not set then default hostdir  is  used.
              For more info on format see 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). For the  file  format  see  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  are  supported.  Without  argument  CPU count is used by
              default.

       --log-server
              Start a log server for sub processes to use. This is  mainly  useful  when  running
              cdist nested from a code- local script. Log server is always implicitly started for
              'install' command.

       -n, --dry-run
              Do not execute code.

       -o OUT_PATH, --out-dir OUT_PATH
              Directory to save cdist output in.

              Operate  on  multiple  hosts  in  parallel  for  specified maximum hosts at a time.
              Without argument CPU count is 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.

       -r REMOTE_OUT_PATH, --remote-out-dir REMOTE_OUT_PATH
              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
       python 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.

SHELL

       This  command allows you to spawn a shell that enables access to the types as commands. It
       can be thought as an "interactive manifest" environment. See below for example usage.  Its
       primary use is for debugging type parameters.

       -s SHELL, --shell SHELL
              Select  shell  to  use,  defaults  to  current  shell.  Used  shell should be POSIX
              compatible shell.

INFO

       Display information for cdist (global explorers, types).

       pattern
              Glob pattern. If it contains special characters('?', '*', '[') then it is  used  as
              specified, otherwise it is translated to *pattern*.

       -h, --help
              Show help message and exit.

       -a, --all
              Display all info. This is the default.

       -c CONF_DIR, --conf-dir CONF_DIR
              Add configuration directory (can be repeated).

       -e, --global-explorers
              Display info for global explorers.

       -F, --fixed-string
              Interpret pattern as a fixed string.

       -f, --full
              Display full details.

       -g CONFIG_FILE, --config-file CONFIG_FILE
              Use specified custom configuration file.

       -t, --types
              Display info for types.

CONFIGURATION

       cdist  obtains  configuration data from the following sources in the following order (from
       higher to lower precedence):

          1. command-line options

          2. configuration file specified at command-line

          3. configuration file specified in CDIST_CONFIG_FILE environment variable

          4. environment variables

          5. user's    configuration    file    (first     one     found     of     ~/.cdist.cfg,
             $XDG_CONFIG_HOME/cdist/cdist.cfg, in specified order)

          6. system-wide configuration file (/etc/cdist.cfg).

   CONFIGURATION FILE FORMAT
       cdist  configuration  file  is in the INI file format. Currently it supports only [GLOBAL]
       section.  The possible keywords and their meanings are as follows:

       archiving
              Use specified archiving. Valid values include: 'none',  'tar',  'tgz',  'tbz2'  and
              'txz'.

       beta   Enable   beta   functionality.   It  recognizes  boolean  values  from  'yes'/'no',
              'on'/'off', 'true'/'false' and '1'/'0'.

       cache_path_pattern
              Specify cache path pattern.

       colored_output
              Colorize cdist's output. cf. the --colors option.

       conf_dir
              List of configuration directories separated with the character conventionally  used
              by  the  operating  system to separate search path components (as in PATH), such as
              ':' for POSIX or ';' for Windows.  If also specified at command  line  then  values
              from command line are appended to this value.

       init_manifest
              Specify default initial manifest.

       inventory_dir
              Specify inventory directory.

       jobs   Specify  number  of jobs for parallel processing. If -1 then the default, number of
              CPU's in the system is used. If 0 then parallel processing in jobs is disabled.  If
              set to positive number then specified maximum number of processes will be used.

       local_shell
              Shell command used for local execution.

       out_path
              Directory to save cdist output in.

       parallel
              Process hosts in parallel. If -1 then the default, number of CPU's in the system is
              used. If 0 then parallel processing of hosts  is  disabled.   If  set  to  positive
              number then specified maximum number of processes will be used.

       remote_copy
              Command to use for remote copy (should behave like scp).

       remote_exec
              Command to use for remote execution (should behave like ssh).

       remote_out_path
              Directory to save cdist output in on the target host.

       remote_shell
              Shell command at remote host used for remote execution.

       save_output_streams
              Enable/disable  saving  output streams (enabled by default).  It recognizes boolean
              values from 'yes'/'no', 'on'/'off', 'true'/'false' and '1'/'0'.

       timestamp
              Timestamp log messages with  the  current  local  date  and  time  in  the  format:
              YYYYMMDDHHMMSS.us.

       verbosity
              Set  verbosity  level.  Valid  values  are:  'ERROR', 'WARNING', 'INFO', 'VERBOSE',
              'DEBUG', 'TRACE' and 'OFF'.

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

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
       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 MaxSessions configuration options. For more details refer to 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:

          init manifest:
              __a a
              require="__e/e" __b b
              require="__f/f" __c c
              __e e
              __f f
              require="__c/c" __d d
              __g g
              __h h

          type __g manifest:
              require="__c/c __d/d" __a a

          Warning message:
              WARNING: cdisttesthost: Object __a/a already exists with requirements:
              /usr/home/darko/ungleich/cdist/cdist/test/config/fixtures/manifest/init-deps-resolver /tmp/tmp.cdist.test.ozagkg54/local/759547ff4356de6e3d9e08522b0d0807/data/conf/type/__g/manifest: set()
              /tmp/tmp.cdist.test.ozagkg54/local/759547ff4356de6e3d9e08522b0d0807/data/conf/type/__g/manifest: {'__c/c', '__d/d'}
              Dependency resolver could not handle dependencies as expected.
