Welcome to the interactive guide to cdist!
|

This is the interactive tutorial and beginners help for cdist and here's
|
||||
our schedule:
|
||||
|

- Stages: How cdist operates
|
||||
- Explorer: Explore facts of the target host
|
||||
- Manifest: Map configurations to hosts
|
||||

|
||||
|
||||
To deploy configurations to a host, you call
|
||||
|
||||
cdist-deploy-to <hostname>
|
||||
|
||||
which makes calls to other scripts, which realise the so called "stages".
|
||||
Usually you'll not notice this, but in case you want to debug or hack cdist,
|
||||
you can run each stage on its own. Besides that, you just need to remember
|
||||
that the command cdist-deploy-to is the main cdist command.

||||

|

|
||||
The first thing cdist always does is running different explorers on the
|
||||
target host. The explorers can be found in the directory
|
||||
|
||||
${__cdist_explorer_dir}
|
||||
|
||||
An explorer is executed on the target host and its output is saved to a file.
|
||||
You can use these files later to decide what or how to configure the host.
|
||||
|
||||
For a demonstration, we'll call the OS explorer locally now, but remember:
|
||||
This is only for demonstration, normally it is run on the target host.
|
||||
The os explorer will which either displays the detected operating system or
|
||||
nothing if it does not know your OS.

# Manifest
|
||||
#
|

cat << eof
|
||||
|
||||
The initial manifest is the entry point for cdist to find out, what you would
|
||||
like to have configured. It is located at
|
||||
|
||||
${__cdist_manifest_init}
|
||||
|
||||
And can be as simple as
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
__file /etc/cdist-configured --type file
|
||||
--------------------------------------------------------------------------------
|
||||

||||

|
||||

||||

|
||||
|
||||
eof
|
||||
__prompt "$continue"
|
||||
|
||||
cat << eof
|
||||
|
||||
Let's take a deeper look at the initial manifest to understand what it means:
|
||||
|
||||
__file /etc/cdist-configured --type file
|
||||
| | | \\
|
||||
| | The parameter type \\ With the value file
|
||||
| |
|
||||
| |
|
||||
| | This is the object id
|
||||
|
|
||||
__file is a so called "type"
|
||||
|
||||
|
||||
This essentially looks like a standard command executed in the shell.
|
||||
eof
|
||||
__prompt "$continue"
|
||||
|
||||
cat << eof
|
||||
|
||||
And that's exactly true. Manifests are shell snippets that can use
|
||||
types as commands with arguments. cdist prepends a special path
|
||||
that contain links to the cdist-type-emulator, to \$PATH, so you
|
||||
can use your types as a command.
|
||||
|
||||
This is also the reason why types should always be prefixed with
|
||||
"__", to prevent collisions with existing binaries.
|
||||
|
||||
The object id is unique per type and used to prevent you from creating
|
||||
the same object twice.
|
||||
|
||||
Parameters are type specific and are always specified as --parameter <value>.

||||

# Types
|
||||
#
|
||||
cat << eof
|
||||
|
||||
Types are bundled functionality and are the main component of cdist.
|
||||
If you want to have a feature x, you write the type __x. Types are stored in
|
||||
|
||||
${__cdist_type_dir}
|
||||
|
||||
And cdist ships with some types already!
|
||||
|
||||
See also:
|
||||
|
||||
cdist-type(7)
|
||||
|
||||
eof
|
||||
__prompt "Press enter to see available types"
|
||||
|
||||
set -x
|
||||
ls ${__cdist_type_dir}
|
||||
set +x
|
||||
|
||||
cat << eof
|
||||
|
||||
Types consist of the following parts:
|
||||
|
||||
- ${__cdist_name_parameter} (${__cdist_name_parameter_required}/${__cdist_name_parameter_optional}
|
||||
- ${__cdist_name_manifest}
|
||||
- ${__cdist_name_explorer}
|
||||
- ${__cdist_name_gencode}
|
||||
|
||||
eof
|
||||
__prompt "$continue"
|
||||
|
||||
|
||||
cat << eof
|
||||
|
||||
Every type must have a directory named ${__cdist_name_parameter}, which
|
||||
contains required or optional parameters (in newline seperated files).
|
||||
|
||||
If an object of a specific type was created in the initial manifest,
|
||||
the manifest of the type is run and may create other objects.
|
||||
|
||||
A type may have ${__cdist_name_explorer}, which are very similar to the
|
||||
${__cdist_name_explorer} seen above, but with a different purpose:
|
||||
They are specific to the type and are not relevant for other types.
|
||||
|
||||
You may use them for instance to find out details on the target host,
|
||||
so you can decide what to do on the target host eventually.
|
||||
|
||||
After the ${__cdist_name_manifest} and the ${__cdist_name_explorer} of
|
||||
a type have been run, ${__cdist_name_gencode} is executed, which creates
|
||||
code to be executed on the target on stdout.

bin/cdist-config and bin/cdist-deploy-to in your favorite editor and

read the scripts bin/cdist-deploy-to calls. The magnificent HACKERS_README

INTRODUCTION
|
||||
------------
|
||||
This tutorial is aimed at people learning cdist and shows
|
||||
typical approaches as well as gives an easy start into
|
||||
the world of configuration management.
|
||||
|
||||
Welcome to the interactive guide to cdist!
|
||||
This is the interactive tutorial and beginners help for cdist and here's
|
||||
our schedule:
|
||||
This tutorial assumes you are configuring **localhost**, because
|
||||
it is always available. Just repace **localhost** with your target
|
||||
host for real life usage.
|
||||
|
||||
- Stages: How cdist operates
|
||||
- Explorer: Explore facts of the target host
|
||||
- Manifest: Map configurations to hosts
|
||||
- Types: Bundled functionality
|
||||
- Deploy a configuration to the local host!

QUICK START
|
||||
-----------
|
||||
For those who just want to configure a system with the
|
||||
cdist configuration management and do not need (or want)
|
||||
to understand everything.
|
||||
|
||||
To deploy configurations to a host, you call
|
||||
|
||||
cdist-deploy-to <hostname>
|
||||
|
||||
which makes calls to other scripts, which realise the so called "stages".
|
||||
Usually you'll not notice this, but in case you want to debug or hack cdist,
|
||||
you can run each stage on its own. Besides that, you just need to remember
|
||||
that the command cdist-deploy-to is the main cdist command.

The first thing cdist always does is running different explorers on the
|
||||
target host. The explorers can be found in the directory
|
||||
|
||||
${__cdist_explorer_dir}
|
||||
|
||||
An explorer is executed on the target host and its output is saved to a file.

||||
You can use these files later to decide what or how to configure the host.
|
||||
|
||||
For a demonstration, we'll call the OS explorer locally now, but remember:
|
||||
This is only for demonstration, normally it is run on the target host.
|
||||
The os explorer will which either displays the detected operating system or
|
||||
nothing if it does not know your OS.

The initial manifest is the entry point for cdist to find out, what you would
|
||||
like to have configured. It is located at
|
||||
|
||||
${__cdist_manifest_init}
|
||||
|
||||
And can be as simple as
|
||||
Cdist uses **ssh** for communication and transportation
|
||||
and usually logs into the **target host** as the
|
||||
**root** user. So you need to configure the **ssh server**
|
||||
of the target host to allow root logins: Edit
|
||||
the file **/etc/ssh/sshd_config** and add one of the following
|
||||
lines:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
__file /etc/cdist-configured --type file
|
||||
# Allow login only via public key
|
||||
PermitRootLogin without-password
|
||||
|
||||
# Allow login via password and public key
|
||||
PermitRootLogin yes

Let's take a deeper look at the initial manifest to understand what it means:
|
||||
|
||||
__file /etc/cdist-configured --type file
|
||||
| | | \\
|
||||
| | The parameter type \\ With the value file
|
||||
| |
|
||||
| |
|
||||
| | This is the object id
|
||||
|
|
||||
__file is a so called "type"
|
||||
|
||||
|
||||
This essentially looks like a standard command executed in the shell.
|
||||
eof
|
||||
__prompt "$continue"
|
||||
|
||||
cat << eof
|
||||
|
||||
And that's exactly true. Manifests are shell snippets that can use
|
||||
types as commands with arguments. cdist prepends a special path
|
||||
that contain links to the cdist-type-emulator, to \$PATH, so you
|
||||
can use your types as a command.
|
||||
|
||||
This is also the reason why types should always be prefixed with
|
||||
"__", to prevent collisions with existing binaries.
|
||||
|
||||
The object id is unique per type and used to prevent you from creating
|
||||
the same object twice.
|
||||
|
||||
Parameters are type specific and are always specified as --parameter <value>.

# Types

cat << eof
|
||||
|
||||
Types are bundled functionality and are the main component of cdist.
|
||||
If you want to have a feature x, you write the type __x. Types are stored in
|
||||
|
||||
${__cdist_type_dir}
|
||||
|
||||
And cdist ships with some types already!
|
||||
|
||||

|
||||
|
||||
cat << eof
|
||||
|
||||
Types consist of the following parts:
|
||||
|
||||
- ${__cdist_name_parameter} (${__cdist_name_parameter_required}/${__cdist_name_parameter_optional}
|
||||
- ${__cdist_name_manifest}
|
||||
- ${__cdist_name_explorer}
|
||||
- ${__cdist_name_gencode}
|
||||
|
||||
eof
|
||||
__prompt "$continue"
|
||||
|
||||
|
||||
cat << eof
|
||||
|
||||
Every type must have a directory named ${__cdist_name_parameter}, which
|
||||
contains required or optional parameters (in newline seperated files).
|
||||
|
||||
If an object of a specific type was created in the initial manifest,
|
||||
the manifest of the type is run and may create other objects.
|
||||
|
||||
A type may have ${__cdist_name_explorer}, which are very similar to the
|
||||
${__cdist_name_explorer} seen above, but with a different purpose:
|
||||
They are specific to the type and are not relevant for other types.
|
||||
|
||||
You may use them for instance to find out details on the target host,
|
||||
so you can decide what to do on the target host eventually.
|
||||
|
||||
After the ${__cdist_name_manifest} and the ${__cdist_name_explorer} of
|
||||
a type have been run, ${__cdist_name_gencode} is executed, which creates
|
||||
code to be executed on the target on stdout.

As soon as you are able to login without passwort to the target host,

we can use cdist, to configure it. You can copy and paste the following

code into your shell to get started and configure localhost:

The file 'conf/manifest/init' is usually the entry point for cdist,

to find out what to configure on which host. All manifests are
|

essentially shell scripts. Every manifest can use the types known to

cdist, which are usually underline prefixed (__).
