My external node classifier returns some arrays in the list of
parameters. Example output (names have been changed to protect the
innocent):
$ ./node_classifier a.b.com
--- %YAML:1.0
"classes": ["class1", "class2", "class3"]
"parameters":
"hostname": "a"
"name": "a"
"domain": "b.com"
"fqdn": "a.b.com"
"group": "<host group>"
"clusters": ["cluster1", "cluster2", "cluster3", "cluster4"]
In my puppet manifests, I would like to be able to use the elements in
the clusters array to generate multiple files to use for the source
parameter of the file type. For example, given the above YML, I'd like
the end result of the file parameter to behave like this:
file { "/etc/somefile.conf":
source => [
"puppet://server/module/configfile.cluster1",
"puppet://server/module/configfile.cluster2",
"puppet://server/module/configfile.cluster3",
"puppet://server/module/configfile.cluster4",
"puppet://server/module/configfile.default"
];
}
However, I can't figure out how to generate the multiple sources from
the array. This (unsurprisingly) doesn't work:
file { "/etc/somefile.conf":
source => [
"puppet://server/module/configfile.$clusters"
];
}
Is what I want to do here possible using the native Puppet language?
Will I need to write a custom function to generate the source files
myself, then pass them to the file type? Is there some other step that
I'm just missing?
Thanks in advance for any help. Getting this to work will save me a
whole lot of time.
