define hostclass with special characters

[sateesh]

Hi,

I need to define the hostclass with special character for ex:
"swift::proxy-ring"

I have tried following ways but not worked:

1) hostclass :swift::proxy-ring do
2) hostclass 'swift::proxy-ring' do
3) hostclass "swift::proxy-ring" do

When I am using the 2 and 3 options it is giving following erroe:

undefined method `[]' for Class:Class at line 1 on node puppet-
swproxy.persistent.co.in

Thanks in advance,
Sateesh B.

Uhm...why? Dashes are not allowed in any puppet classes. Why do you want
them so much? Can you not simply substitute and underscore (_) ?

Cheers,

Hi Felix,

Even I tried to remove that Hiphen and tried. Stil I am getting the
same error.

dir structure is

/modules/swift/manifests/proxyinstall.rb

in this I have declared the class

hostclass "swift::proxyring" do
#code here
end

Still I am getting same error.

Can you give an example for that.

Thanks,
Sateesh B.

sorry the dir structure is /modules/swift/manifests/proxyring.rb

Please give me any example for implementing this. Also when I am
writing Puppet DSL, it is allowing me the dashes.

Sorry, I have no idea what you're trying to do. I never heard of
"hostclass". I just reacted to your statement that "special characters"
were your issue, which struck me as odd.

Also no idea what you are trying to do, but your manifest should have
.pp as it's extension.

Hi,

I found what is the issue. The issue is in exec I am using require
attribute in which I specified

:require => Class['swift::proxy-install']

How should I need to specify this in Ruby DSL.

Thanks,
Sateesh B.

FYI: According to this bug-report, Ruby does not allow a dash in a class name, so neither does Puppet

Try underscore instead: proxy_ring

He is writing in Ruby DSL, not Puppet DSL, which is why the file has
extension .rb. "hostclass" in Ruby DSL is analogous to "class" in
Puppet DSL.

I am by no means well-versed in Ruby DSL, but it seems suspicious to
me that he is passing a String object to the hostclass() function when
that function's usual first argument is a symbol. It is possible that
manually converting the string to a symbol would solve the issue:

hostclass "swift::proxy_ring".to_sym do
# ...
end

Of course, that begs the question of why he wouldn't just write

hostclass :'swift::proxy_ring' do
# ...
end

My Ruby-fu is mediocre at best, but I think the quotes are required
because the symbol's string value contains colons. The initial colon
is definitely required as part of the syntax for a symbol literal.

Hi John,

I have solve that class issue. I have specified that as
hostclass :'swift::proxy-ring' and it worked. My problem is I have to
run the exec command in the script for which the Class "swift::proxy-
install" is required. So, in general puppet DSL we will write that as
follows:

exec {"somelabel":
command => "command here",

require => Class['swift::proxy-install']
}

I need the equivalent Ruby DSL code. I have written the following:

create_resource :exec, "some label", :command => "command
here", :require => Class['swift::proxy-install'].

Here I got error because I place Class['swift::proxy-install'] in
require attribute. As Class is pre-defined in Ruby, we need to write
it another way in Puppet DSL. I want that statement in Ruby DSL.

Thanks in advance,
Sateesh B.

Sateesh,

Still not following why you need to use the Ruby DSL.

There are many great reasons to ultimately use the Ruby DSL, but right now you are seemingly struggling to learn/understand Puppet fundamentals.  I would strongly suggest that the Puppet DSL is there for a reason - it will help you structure your thinking to match the infrastructure you're working with.
