Puppet users - Dec 2010 - What am I doing wrong?

Hello

I need some help with a problem I cant figure out. I tried to look for the
same problem in the puppet forums but I couldn''t find anything.
I have created a custom Type and a custom Provider but I keep getting the
same error not matter what I do. So any help will very appreciated.

My Type is called ''servicemanager''
My Provider is called ''hostmanager''

Please see attachment for these files. And my manifest file looks like:

servicemanager{
    "some_name":
        artifact        =>      "some_name",
        action          =>      stopped,
        release         =>      $releases_file,
        provider        =>      hostmanager;
  }


But I keep getting the following error message:
err: /Stage[main]/some_name/Servicemanager[some_name]: Could not evaluate:
No ability to determine if servicemanager exists

OR
err: Could not run Puppet configuration client: No ability to determine if
servicemanager exists

I even tried adding a def exists? function in hostmanager.rb and that didnt
help.

BTW.. I have "pluginsync = true" on both client and the master in
puppet.conf. Also
my Type "servicemanager.rb"  is in "
/etc/puppet/modules/custom/lib/puppet/type",
and my Provider "hostmanager.rb" is in "
/etc/puppet/modules/custom/lib/puppet/provider/servicemanager"

Thanks
Umair

Puppet handles states not actions. So if you want to define that a service is
running, puppet must have the ability to query if it''s running already.

my comments (your problem is #3 and #4)
1. you use one property for two things. What if you want to say
that your service is installed and running?
2. restarted is not really a state. But you can define that your restart
method should get called upon refresh (look in service.rb how such a
refresh method can be defined)
3. you said ensurable. That''s just a shortcut to say that you have an
ensure property which handles absent and present. This means that your
type (or preferable the provider) must have three functions:
- exists? to retrieve the current state
- create to create your type if it does not exist while it should
- destroy to delete your type if it does exists while it should not
If an ensure property doesnt make any sense for your type dont say
ensurable
4. Your action property doesnt have any retrieve method so puppet cannot
check if this property is in sync or not. Because I guess a
servicemanager resource can be installed AND running, you should split
that at least in two properties. Then you have to define a retrieve
method. The default (defined in property.rb) is to just call
provider.propertyname so just add a method called »action« in
hostmanager.rb. That method must return a valid value
(:stopped or :running).
5. If you define commands :hostmanager => ''...'' you get a
hostmanager
method for free so you can just say:
  hostmanager ''-s'', @resource[:name], ''-r'',
@resource[:release], ''--install''
If you want to have the command as a string #{:hostmanager} just
converts the symbol hostmanager to a string (which is "hostmanager").
I
think what you wanted to say is #{command(:hostmanager)} which will give
you "/usr/local/bin/hostmanager.py"

Hope that helps.

YES ...that helped alot...I got it working now..
Thank you very much

One more question. How can I run hostmanager as a particular user? By
default it runs it as user root.

Thanks

I never used that one but puppet has a util function for that purpose
(asuser defined in util/suidmanager.rb). This SHOULD work:

  Puppet::Util::SUIDManager.asuser(myuid, mygid) do
    hostmanager ''-s'', @resource[:name],
      ''-r'', @resource[:release], ''--install''
  end

You should also test @resource[:release].nil? because the user might not
provide every parameter. Or you should define a default value.

-Stefan

this works...thanks again..
