[Puppet Users] Passing parameters for a class in Dashboard

Or in other words , how do I make sure that following config is applied to
my node through dashboard

class base1 {

package { ["rsync", "xinetd"]: ensure => present }
service { "xinetd": ensure => running }

include rsyncd
$password = generate("/usr/bin/pwgen", 8, 1)

user { "dba":
ensure => present,
comment => "DB user",
gid => "dba",
shell => "/bin/false",
require => Group["dba"],
}

group { "dba":
ensure => present,
}

file { "/backup-mysql":
ensure => directory,
mode => 0775,
owner => "dba",
group => "dba",
}

file { "/home/dba/rsyncd.secret":
content => "backup:${password}",
replace => no,
mode => 0460,
owner=> "root",
group => "dba",
require => User['dba'],
}

rsyncd::export { "backup":
path => "/backup-mysql",
chroot => true,
readonly => true,
uid => "dba",
gid => "dba",
users => "backup",
secrets => "/home/dba/rsyncd.secret",
allow => "192.168.0.0/24",
require => [File["/backup-mysql"], File["/home/dba/rsyncd.secret"]],
}

}

node 'pclient1.example.com' {
include base1
}

In dashboard parameters are assigned via group.

So basically you just create a group, assign some parameters there, include some nodes and your class in it.

Parameters created via dashboard group are at the global top scope I believe.

Hi,

I have recently installed puppet and components including dashboard on my server. I am new to puppet and what I am trying to achieve here is passing parameters via dashboard

What I can see right now is under Add Class in dashboard, I can only pass the class names. Whereas when I can include classes via nodes.pp I can also pass parameters.

How can do this from dashboard,

eg. if I want to achieve the following from dashboard how will I be able to do it

/etc/puppet/manifests/nodes.pp
class baseclass {
class { 'mysql': }
class { 'mysql::server':
#config_hash => { 'root_password' => 'mypass' }
}
mysql::db { 'mydb':
user => 'myuser',
password => 'mypass',
host => 'localhost',
grant => ['all'],
}
}

node 'pclient1.example.com<http://pclient1.example.com/>' {
include baseclass
}


And this is how my site.pp looks like

[[email protected] ~]# cat /etc/puppet/manifests/site.pp
import 'nodes.pp'
$puppetserver = 'pmast1.example.com<http://pmast1.example.com>'
filebucket { "main":
server => "puppet",
path => false,
}
File { backup => "main" }

Please suggest.

Ok.. I understand ... I can simply include the class and assign it to my
node.. but how will dashboard know which parameters refers to which class?

There could be a parameter like "ensure => present" and it could have been
used in multiple classes that I have included, how will these things be
taken care of?

As I said parameters created by dashboard is on top scope.

You can check out puppet’s doc regarding scoping.

Assuming you don’t what to rely on their dynamic lookup (which is what they recommended since the feature is retiring) In your module you can reference global variable directly with the :: prefix.
