NAME
 | 
			
		||||
----
 | 
			
		||||
cdist-explorer - Explore the target systems
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
DESCRIPTION
 | 
			
		||||
-----------
 | 
			
		||||
Explorer are small shell scripts, which will be executed on the target
 | 
			
		||||
host. The aim of the explorer is to give hints to types on how to act on the
 | 
			
		||||
target system. An explorer outputs the result to stdout, which is usually
 | 
			
		||||
a one liner, but may be empty or multi line especially in the case of
 | 
			
		||||
type explorers.
 | 
			
		||||
 | 
			
		||||
There are general explorers, which are run in an early stage, and
 | 
			
		||||
type explorers. Both work almost exactly the same way, with the difference
 | 
			
		||||
that the values of the general explorers are stored in a general location and
 | 
			
		||||
the type specific below the object.
 | 
			
		||||
 | 
			
		||||
Explorers can reuse other explorers on the target system by calling 
 | 
			
		||||
$__explorer/<explorer_name> (general and type explorer) or
 | 
			
		||||
$__type_explorer/<explorer name> (type explorer).
 | 
			
		||||
 | 
			
		||||
In case of significant errors, the explorer may exit non-zero and return an
 | 
			
		||||
error message on stderr, which will cause the cdist run to abort.
 | 
			
		||||
 | 
			
		||||
You can also use stderr for debugging purposes while developing a new
 | 
			
		||||
explorer.
 | 
			
		||||
 | 
			
		||||
EXAMPLES
 | 
			
		||||
--------
 | 
			
		||||
A very simple explorer may look like this:
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
hostname
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Which is in practise the "hostname" explorer.
 | 
			
		||||
 | 
			
		||||
A type explorer, which could check for the status of a package may look like this:
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
if [ -f "$__object/parameter/name" ]; then
 | 
			
		||||
   name="$(cat "$__object/parameter/name")"
 | 
			
		||||
else
 | 
			
		||||
   name="$__object_id"
 | 
			
		||||
fi
 | 
			
		||||
 | 
			
		||||
# Except dpkg failing, if package is not known / installed
 | 
			
		||||
dpkg -s "$name" 2>/dev/null || exit 0
 | 
			
		||||
--------------------------------------------------------------------------------

		||||
 |

 | 
			
		||||
DESCRIPTION
 | 
			
		||||
-----------
 | 
			
		||||
Various scripts which are not in the core need information on how
 | 
			
		||||
to find information. This manpage summarises the available environment
 | 
			
		||||
variables, types and paths and clearifies with part may access which variables.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
PATHS
 | 
			
		||||
-----
 | 
			
		||||
If not specified otherwise, all paths are relative to the checkout directory.
 | 
			
		||||
 | 
			
		||||
conf/::
 | 
			
		||||
   Contains the (static) configuration like manifests, types and explorers.  
 | 
			
		||||
 | 
			
		||||
conf/manifest/init::
 | 
			
		||||
   This is the central entry point used by cdist-manifest-init(1).
 | 
			
		||||
   It is an executable (+x bit set) shell script that can use
 | 
			
		||||
   values from the explorers to decide which configuration to create
 | 
			
		||||
   for the specified target host.
 | 
			
		||||
 | 
			
		||||
   It should be primary used to define mapping from configurations to hosts.
 | 
			
		||||
 | 
			
		||||
conf/manifest/*::
 | 
			
		||||
   All other files in this directory are not directly used by cdist, but you
 | 
			
		||||
   can seperate configuration mappings, if you have a lot of code in the
 | 
			
		||||
   manifest/init file. This may also be very helpful to have different admins
 | 
			
		||||
   maintain different groups of hosts.
 | 
			
		||||
 | 
			
		||||
conf/explorer/<name>::
 | 
			
		||||
   Contains explorers to be run on the target hosts, see cdist-explorer(7).
 | 
			
		||||
 | 
			
		||||
conf/type/::
 | 
			
		||||
   Contains all available types, which are used to provide
 | 
			
		||||
   some kind of functionality. See cdist-type(7).
 | 
			
		||||
 | 
			
		||||
conf/type/<name>/::
 | 
			
		||||
   Home of the type <name>.
 | 
			
		||||
 | 
			
		||||
   This directory is referenced by the variable __type (see below).
 | 
			
		||||
 | 
			
		||||
conf/type/<name>/manifest::
 | 
			
		||||
   Used to generate additional objects from a type.
 | 
			
		||||
 | 
			
		||||
conf/type/<name>/gencode::
 | 
			
		||||
   Used to generate code to be executed on the client.
 | 
			
		||||
 | 
			
		||||
conf/type/<name>/parameters/required::
 | 
			
		||||
   Parameters required by type, \n seperated list.
 | 
			
		||||
 | 
			
		||||
conf/type/<name>/parameters/optional::
 | 
			
		||||
   Parameters optionally accepted by type, \n seperated list.
 | 
			
		||||
 | 
			
		||||
conf/type/<name>/explorer::
 | 
			
		||||
   Location of the type specific explorers.
 | 
			
		||||
 | 
			
		||||
   This directory is referenced by the variable __type_explorer (see below).
 | 
			
		||||
 | 
			
		||||
   See cdist-explorer(7).
 | 
			
		||||
 | 
			
		||||
out/::
 | 
			
		||||
   This directory contains output of cdist and is usually located
 | 
			
		||||
   in a temporary directory and thus will be removed after the run.
 | 
			
		||||
 | 
			
		||||
   This directory is referenced by the variable __global (see below).
 | 
			
		||||
 | 
			
		||||
out/explorer::
 | 
			
		||||
   Output of general explorers.
 | 
			
		||||
 | 
			
		||||
out/object::
 | 
			
		||||
   Objects created for the host.
 | 
			
		||||
 | 
			
		||||
out/object/<object>::
 | 
			
		||||
   Contains all object specific information.
 | 
			
		||||
 | 
			
		||||
   This directory is referenced by the variable __object (see below).
 | 
			
		||||
 | 
			
		||||
out/object/<object>/explorers::
 | 
			
		||||
   Output of type specific explorers, per object.
 | 
			
		||||
 | 
			
		||||
tmp_dir::
 | 
			
		||||
   A tempdir and a tempfile is used by cdist internally,
 | 
			
		||||
   which will be removed when the scripts end automatically.
 | 
			
		||||
   See cdist-config(1).

NAME
 |

----
 | 
			
		||||
cdist-type-listing - Available types in cdist
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
SYNOPSIS
 | 
			
		||||
--------
 | 
			
		||||
Types that are included in cdist $(git describe).
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
DESCRIPTION
 | 
			
		||||
-----------
 | 
			
		||||
Types are the main component of cdist and define functionality. If you
 | 
			
		||||
use cdist, you'll write a type for every functionality you would like
 | 
			
		||||
to use.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
HOW TO USE A TYPE
 | 
			
		||||
-----------------
 | 
			
		||||
You can use types from the initial manifest or the type manifest like a
 | 
			
		||||
normal command:
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
# Creates empty file /etc/cdist-configured
 | 
			
		||||
__file /etc/cdist-configured --type file
 | 
			
		||||
 | 
			
		||||
# Ensure tree is installed
 | 
			
		||||
__package tree --state installed
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Internally cdist-type-emulator(1) will be called from cdist-manifest-run(1) to
 | 
			
		||||
save the given parameters into a cconfig database, so they can be accessed by
 | 
			
		||||
the manifest and gencode scripts of the type (see below).
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
HOW TO WRITE A NEW TYPE
 | 
			
		||||
-----------------------
 | 
			
		||||
A type consists of
 | 
			
		||||
 | 
			
		||||
- parameter (optional)
 | 
			
		||||
- manifest  (optional)
 | 
			
		||||
- explorer  (optional)
 | 
			
		||||
- gencode   (optional)
 | 
			
		||||
 | 
			
		||||
Types are stored below conf/type/. Their name should always be prefixed with
 | 
			
		||||
two underscores (__) to prevent collisions with other binaries in $PATH.
 | 
			
		||||
 | 
			
		||||
To begin a new type from a template, execute "cdist-type-template __NAME"
 | 
			
		||||
and cd conf/type/__NAME.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
DEFINING PARAMETERS
 | 
			
		||||
-------------------
 | 
			
		||||
Every type consists of optional and required parameters, which must
 | 
			
		||||
be created in a newline seperated file in parameters/required and
 | 
			
		||||
parameters/optional. If either or both missing, the type will have
 | 
			
		||||
no required, no optional or no parameters at all.
 | 
			
		||||
 | 
			
		||||
Example:
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
echo servername >> conf/type/__nginx_vhost/parameter/required
 | 
			
		||||
echo logdirectory >> conf/type/__nginx_vhost/parameter/optional
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
WRITING THE MANIFEST
 | 
			
		||||
--------------------
 | 
			
		||||
In the manifest of a type you can use other types, so your type extends
 | 
			
		||||
their functionality. A good example is the __package type, which in
 | 
			
		||||
a shortened version looks like this:
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
os="$(cat "$__global/explorer/os")"
 | 
			
		||||
case "$os" in
 | 
			
		||||
      archlinux) type="pacman" ;;
 | 
			
		||||
      debian|ubuntu) type="apt" ;;
 | 
			
		||||
      gentoo) type="emerge" ;;
 | 
			
		||||
      *)
 | 
			
		||||
         echo "Don't know how to manage packages on: $os" >&2
 | 
			
		||||
         exit 1
 | 
			
		||||
      ;;
 | 
			
		||||
esac
 | 
			
		||||
 | 
			
		||||
__package_$type "$@"
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
 | 
			
		||||
As you can see, the type can reference different environment variables,
 | 
			
		||||
which are documented in cdist-environment-variables(7).
 | 
			
		||||
 | 
			
		||||
Always ensure the manifest is executable, otherwise cdist will not be able
 | 
			
		||||
to execute it.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
THE TYPE EXPLORERS
 | 
			
		||||
------------------
 | 
			
		||||
If a type needs to explore specific details, it can provide type specific
 | 
			
		||||
explorers, which will be executed on the target for every created object.
 | 
			
		||||
 | 
			
		||||
The explorers are stored under the "explorer" directory below the type.
 | 
			
		||||
It could for instance contain code to check the md5sum of a file on the
 | 
			
		||||
client, like this (shortened version from real type __file):
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
if [ -f "$__object/parameter/destination" ]; then
 | 
			
		||||
   destination="$(cat "$__object/parameter/destination")"
 | 
			
		||||
else
 | 
			
		||||
   destination="/$__object_id"
 | 
			
		||||
fi
 | 
			
		||||
 | 
			
		||||
if [ -e "$destination" ]; then
 | 
			
		||||
   md5sum < "$destination"
 | 
			
		||||
fi
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
WRITING THE GENCODE SCRIPT
 | 
			
		||||
--------------------------
 | 
			
		||||
The gencode script can make use of the parameters, the global explorers
 | 
			
		||||
and the type specific explorers. The output (stdout) of this script is
 | 
			
		||||
saved by cdist and will be executed on the target.
 | 
			
		||||
 | 
			
		||||
If the gencode script encounters an error, it should print diagnostic
 | 
			
		||||
messages to stderr and exit non-zero. If you need to debug the gencode
 | 
			
		||||
script, you can write to stderr:
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
# Debug output to stderr
 | 
			
		||||
echo "My fancy debug line" >&2
 | 
			
		||||
 | 
			
		||||
# Output to be saved by cdist for execution on the target
 | 
			
		||||
echo "touch /etc/cdist-configured"
 | 
			
		||||
--------------------------------------------------------------------------------
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
HINTS FOR TYPEWRITERS
 | 
			
		||||
----------------------
 | 
			
		||||
It must be assumed that the target is pretty dumb and thus does not have high
 | 
			
		||||
level tools like ruby installed. If a type requires specific tools to be present
 | 
			
		||||
on the target, there must be another type that provides this tool and the first
 | 
			
		||||
type should create an object of the specific type.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
HOW TO INCLUDE A TYPE INTO UPSTREAM CDIST
 | 
			
		||||
-----------------------------------------
 | 
			
		||||
If you think your type may be useful for others, ensure it works with the
 | 
			
		||||
current master branch of cdist and submit the git url containing the type for
 | 
			
		||||
inclusion to the mailinglist **cdist at cdist -- at -- l.schottelius.org**.
 | 
			
		||||
 | 
			
		||||
Ensure a corresponding manpage named cdist-type__NAME is included.

cdist-config-layout - Usage of paths in cdist
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
DESCRIPTION
 | 
			
		||||
-----------
 | 
			
		||||
If not specified otherwise, all paths are relative to the configuration
 | 
			
		||||
directory, which is normally /etc/cdist (but can be changed using environment
 | 
			
		||||
variables, see cdist-environment(7)).
 | 
			
		||||
 | 
			
		||||
- conf_dir/:
 | 
			
		||||
   Contains the (static) configuration like manifests, types and
 | 
			
		||||
   explorers.
 | 
			
		||||
 | 
			
		||||
- conf_dir/manifest/init:
 | 
			
		||||
   This is the central entry point used by cdist-manifest-init(1).
 | 
			
		||||
   It is an executable (+x bit set) shell script that can use
 | 
			
		||||
   values from the explorers to decide which configuration to create
 | 
			
		||||
   for the specified target host.
 | 
			
		||||
 | 
			
		||||
   It should be primary used to define mapping from configurations to hosts.
 | 
			
		||||
 | 
			
		||||
- conf_dir/manifest/*:
 | 
			
		||||
   All other files in this directory are not directly used by Cdist, but you
 | 
			
		||||
   can seperate configuration mappings, if you have a lot of code in the
 | 
			
		||||
   manifest/init file. This may also be very helpful to have different admins
 | 
			
		||||
   maintain different groups of hosts.
 | 
			
		||||
 | 
			
		||||
- conf_dir/explorer/<name>
 | 
			
		||||
   Contains explorers to be run on the target hosts, see cdist-explorers(7).
 | 
			
		||||
 | 
			
		||||
- conf_dir/type/
 | 
			
		||||
   Contains all available types, which are used to provide
 | 
			
		||||
   some kind of functionality. See cdist-stages(7).
 | 
			
		||||
 | 
			
		||||
- conf_dir/type/<name>/manifest:
 | 
			
		||||
   Used to generate additional objects from a type.
 | 
			
		||||
   See cdist-stages(7), cdist-types(7).
 | 
			
		||||
 | 
			
		||||
- conf_dir/type/<name>/gencode:
 | 
			
		||||
   Used to generate code to be executed on the client.
 | 
			
		||||
   See cdist-types(7).
 | 
			
		||||
 | 
			
		||||
- conf_dir/type/<name>/parameters/required:
 | 
			
		||||
   Parameters required by type, \n seperated list.
 | 
			
		||||
   See cdist-types(7).
 | 
			
		||||
 | 
			
		||||
- conf_dir/type/<name>/parameters/optional:
 | 
			
		||||
   Parameters optionally accepted by type, \n seperated list.
 | 
			
		||||
   See cdist-types(7).
 | 
			
		||||
 | 
			
		||||
- conf_dir/type/<name>/explorer:
 | 
			
		||||
   Location of the type specific explorers.
 | 
			
		||||
   See cdist-explorers(7).
 | 
			
		||||
 | 
			
		||||
- out_dir/
 | 
			
		||||
   This directory contains output of cdist and is mirrored into the
 | 
			
		||||
   cache after a successful run. This directory may be placed below
 | 
			
		||||
   the tmpdir or at any other location and is also available on the
 | 
			
		||||
   target.
 | 
			
		||||
 | 
			
		||||
- out_dir/explorer:
 | 
			
		||||
   Output of general explorers.
 | 
			
		||||
 | 
			
		||||
- out_dir/object:
 | 
			
		||||
   Objects created for the host.
 | 
			
		||||
 | 
			
		||||
- out_dir/object/<object>/explorers:
 | 
			
		||||
   Output of type specific explorers, per object.
 | 
			
		||||
 | 
			
		||||
- tmp_dir: Temporary storage
 | 
			
		||||
   A tempdir and a tempfile is provided by cdist-config(1), which
 | 
			
		||||
   will be removed when the scripts ends automatically.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
FUTURE
 | 
			
		||||
------
 | 
			
		||||
The following functionality may be implemented in one of the next releases:
 | 
			
		||||
 | 
			
		||||
- cache_dir/
 | 
			
		||||
   The cache contains the out_dir from previous runs, which
 | 
			
		||||
   may also be used in types to gather information about other hosts
 | 
			
		||||
   (like ssh-keys).
 | 
			
		||||
 | 
			
		||||
- cache_dir/host/<name>:
 | 
			
		||||
   Contains the last out_dir of the specific host.

cdist-explorer - Explore the target systems
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
DESCRIPTION
 | 
			
		||||
-----------
 | 
			
		||||
Cdist explorer are small shell scripts, which will be executed
 | 
			
		||||
on the target host. The aim of the explorer is to give hints
 | 
			
		||||
to types on how to act on the target system.
 | 
			
		||||
The explorer output the result of its investigation
 | 
			
		||||
to stdout and should be a one-liner. The output may be empty,
 | 
			
		||||
though.
 | 
			
		||||
 | 
			
		||||
Cdist knows about general explorers, which are run in an early
 | 
			
		||||
stage and type specific explorers. Both work exactly the same way,

 | 
			
		||||
will cause the cdist run to abort.
