Aaron, I think this is a completely sane request.  We've talked about
it before, but I can't find an existing ticket.  This one seems close,
but very old; will you take a look?
http://projects.puppetlabs.com/issues/1858

If we can work out a good syntax we'll put this on the roadmap.  I
know some of our PS guys are eager for it, too.

Re: [Puppet Users] Virtual resources and hashes

2011-06-08 Thread Aaron Grewell
The request in the ticket is related but might not solve the same problem.
What I think I'm looking for is the generic ability to specify an array of
hashes as a resource title and have Puppet handle it intelligently (that is,
produce a locally scoped hash split from the array and easily accessible
inside the resource specification as well as knowing what value it should
use for $name or supporting e.g. $alias = hash[key] for specifying the
appropriate value).  The reason I think that's preferable to the ability to
transform a hash to a resource is because it will work everywhere.  What I
don't know is whether the hash - resource transform can be made to declare
an instance of a define().  If so, it would handle my needs quite well.  If
OTOH it will only declare native resource types then it won't do all of what
I'm looking for.  It would be a step in the right direction though.

[Puppet Users] Virtual resources and hashes

2011-06-07 Thread Aaron Grewell
Hmmm, either I'm doing something wrong or virtual resources are incompatible
with hashes.

When I do this:
$users = [{ username = bill, uid = 12345 },
 { username = ted,  uid = 12346 }]

define usertest ($alias = $name[username]) {
user {$name[username]:
ensure = present,
uid= $name[uid]
}
}
@usertest { $users: }
realize Usertest[bill]

I get this:
warning: alias is a metaparam; this value will inherit to all contained
resources
Failed to realize virtual resources Usertest[bill] on node

Which seems unfortunate.  Hash support is a really cool idea but I keep
tripping over parts of Puppet that don't handle it well.
