I'm trying to use a trick similar to the one here https://docs.puppet.com/hiera/1/variables.html where (instead of a fact) I define a variable in my node definition, and then use the value of that variable to possibly find a data source in hiera.
My hiera.yaml looks like this:
:hierarchy:
- %{hostname}
- "sts_%{::sts}"
- global
global.yaml includes this line:
test3::one: global
sts_1.yaml includes this line:
test3::one: sts_1.yaml
and my test3 class is
class test3
(
$one = "xxxxx one",
)
{
notify { "module $hostname $module_name: \$one $one" : }
}
When I use this node
node 'agent3'
{
include test3
}
I get the answer I expect
> Notice: module agent3 test3: $one global
But when I set my variable
node 'agent3'
{
$sts=1
include test3 <- this is line 25
}
I get an error
> Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Evaluation Error: Error while evaluating a Function Call, Error from DataBinding 'hiera' while looking up 'test3::one': can't convert Fixnum into String at /etc/puppet/manifests/site.pp:25:3 on node agent3
When I change my node
node 'agent3'
{
$sts="1"
include test3
}
Then it works again
> Notice: module agent3 test3: $one sts_1.yaml
So clearly, the problem is the variable being passed as the number 1 rather than the string "1".
However, the doc https://docs.puppet.com/hiera/1/variables.html tells me that it should be OK to do this:
> Hiera can only interpolate variables whose values are strings. (Numbers from Puppet are also passed as strings and can be used safely.)
So ... what am I doing wrong?
