Puppet users - Jun 2008 - HOWTO: Bootstrapping environments without external node classifers.

Hi,

I''ve just spent the day, after discussions with Volcane (who deserves
all
the credit for this idea) setting up my site to handle environments without
having to use an external node classifier.  I thought I''d just jot down
quickly what I did in case it''s helpful to anyone else.  To set the
environment you need to edit puppet.conf on all your clients and insert
"environment = environmentname", so to handle this we have
reconfigured
puppetmaster to use a default environment of bootstrap that then sets the
variable in puppet.conf, allowing you to place a variable in your node
statements which will then configure the node into an environment.

I generally include baseclass on all my nodes, and have a templates.pp that
includes this.  I have switched to calling a define in each node that sets
either ''include baseclass'' or ''include
bootstrap'' depending on what
environment is set, and I will list all the required bits below:

site.pp
---------

define defaultclass() {
    case $name {
        "": {include bootstrap}
        default: {include baseclass}
    }
}

node.pp
-----------

node "examplenode" {
    $localenvironment = "development"
    defaultclass{$environment:}
}


templates.pp
------------------

class baseclass {
    include regularmodules
}

class bootstrap {
        include network
        include puppet
        include repos
}

puppet module in bootstrap
---------------------------------------
class puppet {

    file { "/etc/puppet/puppet.conf":
        ensure => present,
        content => template("puppet/puppet.conf.erb"),
    }
}

In puppet.conf.erb
--------------------------

[main]
environment = <%= localenvironment %>

puppet.conf on the puppetmaster
-----------------------------------------------

[puppetmasterd]
    environments = production,development,bootstrap (stick your environments
on here)
    environment = bootstrap
[bootstrap]
modulepath = /etc/puppet/modules/bootstrap

Lak:

Are we correct in that setting environment = bootstrap in [puppetmasterd]
should mean that any client without an environment set in puppet.conf should
attempt to use bootstrap?  It still seems to be pulling from the development
modules by default and I''m not sure if my define is broken or
I''m
misunderstanding how the default environment system works.

make you want to do work. make the following changes:


 puppet.co>
I was about to reply to orginal post on this. You are missing a key
point. I ran in to this also when setting this. Here is the break down
of the issue:

1) The client overrides the the server environmentsetting everytime.
This good lets you set client enviroments.

2) The client default environment is development. This can be bad as
it will always override the Server environment.

To make what you want work, remove the environment setting from
[puppetmasterd]. The first time you launch puppetd have launch puppetd
--environment=bootstrap to use the bootstrap environment.


If you want the long and grit discussion on this check the archives. I
sort of set off a long discussion about this a few months ago.
