Hi,
Seems it is not possible, well, I cannot make it work.
Depending on some class parameter, some exported resources should be collected
or not.
eg.
class X (
$collect_tags = ['cond1', 'cond2']
) {
$my_cond = my_magic_function($collect_tags) # returns the string "tag ==
'cond1' or tag=='cond2'"
My_exp_res <<| $my_cond |>>
}
But the only result I get : Error 400 on SERVER: Syntax error at '|>>';
expected '}'
Whatever i tried, nothing gave me the desired result. Using single quotes,
double quotes, escaping quotes ....
And <<| tag == $collect_tags |>> ( <<| tag == ['cond1','cond2'] |>> does not
give me the desired result, only one exported resource is collected. But I try
to ovoid this, because the behavior of this i unpredictable, as documented in
the docs.
I already I'm a big fan of iteration, but this needs to work on puppet 3.[7|8].x
For now I will change my parameter to a single string and us an if clause like
...
if ( $collect_tag =~ /all$/ ) {
My_exp_res <<| |>>
} else {
My_exp_res <<| tag == $collect_tag >>
}
I will loose the ability to collect on multiple nodes this way, but we can live
with this for the moment.
Peeking to puppetdbquery as an alternative ....
