I think you are saying that for each Tomcat instance you want to ensure the
same files present in the same directory (rather than in distinct,
instance-specific directories). The key problem with your approach to that
is you are trying to manage the driver files as if they belong to
individual instances, whereas they actually belong to Tomcat overall.
The available solutions fall into two categories:
1. Give each Tomcat instance its own, separate copies of the files.
2. Factor the affected file resources out of your Tomcat instance
definition, and instead manage them in one central place for all
instances. The most likely way to do this would be to put them into a
class that the instance definition declares (which works because Puppet
classes are idempotent).
Example:
class tomcat::db_drivers {
include 'tomcat'
file { "$tomcat_root/lib/mysql.jar":
ensure => 'present',
source => 'puppet://modules/tomcat/mysql.jar'
}
...
}
define tomcat::instance(...) {
include 'tomcat'
include 'tomcat::db_drivers'
# instance-specific resources ...
}

[Puppet Users] Re: Copying multiple files to multiple locations
Hi Matthijs,
You can try using array variable in file resource.This may solve your
issue. Can you explain in detail. I mean the location of files and
directory structures.
If you want to copy the same file content in several files refer following
code snippet,You can use various files path in array.
$file_names = ['/root/t1',/root/t2',/root/t3',/root/t4']
file { $file_names:
ensure => file,
content => 'xyz',
}
You can also use source => '/root/xyz.txt' tag/attribute of file resource
for coping whole file.
This copied the 'xyz' content in all the files present in $file_name array
variables.
Thanks & Regards,
