Puppet users - Jun 2013 - trying to get a 32-bit JVM on a 64-bit platform with Package provider

i was hoping I could do this with the right ensure parameter on Package,
but I''m hitting a wall.

We''ve got 64-bit servers running tomcats on RHEL that need to be 32-bit
(external vendor, JNI, funny story).

2.7 Puppetmaster and the yum repo hosts the Oracle JDKs.



Currently we just push out what we want with:

class jdk {
  package { "jdk": ensure => present }
}

which essentially does ''yum install jdk'' (some other bits too,
but
they''re not relevant).

I was hoping to include something like

class jdk::32bit inherits jdk {

  Package[''jdk''] { ensure => "1586" }
}

for these servers, but that seems to run the equivalent of : yum
install jdk-i586

Is there a way to coerce the resource to install the right thing, or
am I going to have
to go with an Exec ?

Ah cracked it!

class jdk::32bit inherits jdk {

  Package[''jdk''] { ensure => undef }

  package { "jdk.i586": ensure => present }

}

Package[''jdk''] { 
        name => ''jdk.i1586''
    }

will be a better option. Note that I wouldn''t use inheritance here but
a
simple parameter for the package name and move that somewhere else like
hiera(although I see that you are using puppet2.7)

Inheritance is almost always not the right answer.

I know, I''m starting to migrate to parameterised classes or similar,
need to unlearn some bad habits. Thanks!
