Puppet users - Dec 2011 - Using array's in Puppet (in combination with Augeas).

Hi,

I have been struggling with arrays in puppet in combination with
Augeas. I have written a define to configure network interfaces on
Debian based distributions using Augeas. One of the requirements is
the possibility to use the up/down mechanism.

This where I run into a snag. Everything works fine until I try to
setup more than than one up rule.  First some code examples of the
define:

-- Node Configuration --
networking::managed_interface { ''eth1'':
            int            => ''eth1'',
            ipaddr      => ''192.168.1.123'',
            netmask   => ''255.255.255.0'',
            up             => ''route add -net 172.16.1.0/24 gw
192.168.1.1''
    }

-- networking::managed_interface (only the up segment) --
    if $up != '''' {

        augeas{ "up-${device}" :
            context   => ''/files/etc/network/interfaces'',
            changes => [
                "set iface[. = ''${device}'']/up[. =
''${up}'' ] \"${up}
\"",
            ],
         }

    }

So this works fine but I would like to be able to add multiple up
rules. I was thinking about passing multiple rules as an array:

   up      => [''route add -net 172.16.1.0/24 gw
192.168.3.1'', ''route
add -net 192.168.12.0/24 gw 192.168.3.1'']

And use some kind of for/while loop in Puppet to iterate over the
array but to my surprise Puppet has no way of doing this... I searched
the documentation, google and the google-group but there seems to be
no way of iterating over an array or even get the size of an array.

So now I am kind of stuck. I could write a separate define for the up
rules but I would rather have this within the define for interfaces.

I am probably not the first to have run into this and I am curious as
how others have solved this "problem"

Regards,

Adrian.

No, that''s how you generally do it.

Make a defined type that does the required augeas to add an
''up'' rule,
then have your interfaces define make one of those ''up''
resources per
array element.

Sorry For The Inconvenience ;-)

Cheers,
Felix
