Hi all,
I have a couple of "basic" questions on classes.
In a class, what's the diff between:
*don't take in count syntax, please.
----------------------------------
class class_B {
package { fortune }
file { dummy }
}
----------------------------------
example 1)
class class_A {
import class_B
package { foo }
example 2)
class class_A {
file { bogus
before = > Package [foo],
}
package { foo
require => Class["class_B"],
}
}
example 3)
class class_A inherits class_B {
package { foo }
In first example class_B will be evaluated before ALL class_A.
so package fortuen and dummy file will be installed/created before
package foo.
In second one, class_B will be evaluted ONLY when package
foo. So, first bogus package, then, before foo, fortune and summy file.
And on third example? same as first one?
I don't see difference between example 1 and 3.
All comes from some examples from David Schmitt:
http://git.black.co.at/?p=module-ssh;a=blob;f=manifests/init.pp;h=9c87f5956b9c10a5fa422044a43ba38b27a4b96f;hb=9ccdd6ed46031db9001f9b71285455c297f56dfc
5 class ssh::common {
6 file {
7 "/etc/ssh":
8 ensure => directory,
9 mode => 0755, owner => root, group => root,
10 }
11 group {
12 ssh:
13 gid => 204,
14 allowdupe => false,
15 }
16 }
17
18 class ssh::client inherits ssh::common {
19 package {
20 "openssh-client":
21 ensure => installed,
22 require => [ File["/etc/ssh"], Group[ssh] ],
23 }
[...]
Why is he requering File and Group if class ssh::client inherits
ssh:common?
Oh, if I include class_B in class_A, node def should be enough with:
node "node.bogus.com" {
include class_A
}
right?
TIA,
Arnau
