Hierarchy in puppet classes

[AAB !!]

Hi,

 Could someone tell me how can I have hierarchy in puppet classes ?.

I have some classes for services like ntp,ssh and many more. What I want is, these classes should be included for every puppet agent/node. Could I make a parent class and include these classes into in. And then in the node file for agent I can include only this parent class.

 Now in future if I have to include any new basic service like *backup* I dont have to edit the node file for each node to include the backup class, I  will simply  include the backup class in the parent class and all of my nodes will have that backup configuration.

Regards

Hi,

this exactly is the reason why one should make use of roles and profiles
see
http://www.craigdunn.org/2012/05/239/
http://projects.puppetlabs.com/projects/puppet/wiki/Infrastructure_Design_Guidelines
http://docs.puppetlabs.com/pe/latest/puppet_assign_configurations.html#assigning-configuration-data-with-role-and-profile-modules

Personally I prefer a module with the name “role”

e.g.
role/manifests/base.pp

class role::base {
include ntp
include backup
include security
}

And within my node I am using this role:

node ‘foobar’ {
include role::base
...
}


hth,

Martin

Bundle of thanks !! But should this be a directory structure i.e.  role/manifests/base ???

and what would be the name of the file class which has 

class role::base {
  include ntp
  include backup
  include security
}

is it base.pp in role/manifests/ directory ???

This is the basic concept of puppet modules.
On your master you have configured at least one module path (look into puppet.conf on your master).
Within that directory you build your modules:
<modulepath>/<modulename>/manifests/<classname>.pp

class role::base

role = modulename
base = filename without file ending in <modulepath>/<modulename>/manifests

yes.
