Hi,
I'm trying to create a squid url_regex ACL source file for various
different sites. Each site needs a slightly different configuration, so
my plan was to create the a bunch of files on the server, then drag them
down and concatenate them into a single file on the client.
I found http://reductivelabs.com/trac/puppet/wiki/CompleteConfiguration
and i've been trying to understand its approach to constructing a file
out of fragments. Am i right in thinking that i need to distribute an
entire directory from the server, then use concatenated_file to combine
those files into one file on the puppet agent?
I'd rather not distribute the entire directory from the server, since it
contains custom content for each node. Is there a way i can do this
with templates that include other files? (Or templates that are plain
text rather than .erb?) I'd really like to find a technique that
doesn't require separately copying the file fragments to the client also...
I've had 3 or 4 tries at getting the right approach and am still no
closer to a working solution. Attached is my non-working attempt at a
class to do this - what am i doing wrong? (Comments about what's not
working can be found after the @@@ comments.) I thought this was a
fairly simple problem, but i've been banging my head against it all day
without any success.
