Nested arrays in puppet....

[Craig Dunn]

I'm trying to nest arrays within puppet to use in an ERB template... is
this something thats supported in puppet.

Im defining my variable as:

$var = [ [ foox, fooy ], [ barx, bary ] ]

Within my erb template, I'm doing:

var.each { |x,y|
%>
X: <%= x %>
Y: <%= y %>
<%
}
%>

This seems to work when I test it with a simple Ruby script, but when my
ERB template gets it from puppet it seems to have flattened the array,
any way to stop this from happening?

Cheers
Craig

I haven't seen a way to do this, because puppet's configuration has limited datatypes.

To do something similar, I encoded the same data in strings.

I used this snippet in my manifest:

sources => ["key1/host1:1234", "key2/host2:1234"]

And this snippet in my template:

<%# syntax is "<name>/<source>" %>
<% sources.each do |source| -%>
data_source <%= source.split("/")[0] %> <%= source.split("/")[1] %>
<% end -%>
