Re: Hiera cannot interpolate non-string values
Perhaps we should have something identical to the strict_alias proposed in PUP-8593?. Given that an interpolation without any function is identical to scope, we could make strict imply a strict lookup in scope. E.g.
docker::selinux_enabled: "%{strict('facts.selinux.enabled')}"
would give the desired result.

Jira (HI-599) Hiera cannot interpolate non-string values
Title: Message Title Henrik Lindberg commented on HI-599 Re: Hiera cannot interpolate non-string values The solution is to write a simple hiera backend function (in the puppet language) that returns the value. Alternatively if the String form can be parsed (for example for Integer, Boolean and Float values), the existing type casting feature in lookup_options works - i.e. transforming the string value back to the original data type. This in wait of the possible alias feature mentioned above (possibly) being introduced.

Title: Message Title Henrik Lindberg commented on HI-599 Re: Hiera cannot interpolate non-string values Rune Juhl Jacobsen Modifying YAML to be non standard is not a happy path. Going there, you would need to invent a new hiera format. Note that if you write a lookup_key kind of hiera backend function you handle interpolations yourself, and you can either call the built in standard "hiera 3 like" interpolation or do it some other way. That means you can process results with your own interpolation mechanism.

Jira (HI-599) Hiera cannot interpolate non-string values
Title: Message Title Rune Juhl Jacobsen commented on HI-599 Re: Hiera cannot interpolate non-string values Since you're already using YAML, maybe it would make sense to make use of the existing syntax for YAML anchors? Instead of making the Hiera-specific syntax more convoluted by adding an optional argument for type coercion, as suggested in comment #1, this would keep the syntax (relatively) simple. According to the YAML 1.2 spec there shouldn't be any problem with anchors containing any of the valid characters for Puppet identifiers, i.e. an anchor like *::some::weird_identifier::here is perfectly fine. With that it would be possible to use any types in facts without having to explicitly state the type. I imagine it's possible to hook into the YAML deserialization to make this possible. Of course, this means that Puppet YAML breaks the YAML spec by abusing anchors, but I imagine that not many people use YAML anchors, and even less people use YAML anchors with :: in them, making this less of an issue.

Title: Message Title Trevor Vaughan commented on HI-599 Re: Hiera cannot interpolate non-string values Henrik Lindberg I think that scope should work the same way as alias. It makes sense. I can see that some people might rely on that but that seems like a bug and should be treated as such. In theory, your Hiera data is getting passed into your classes and everything should be strongly typed at this point (hopefully).

Jira (HI-599) Hiera cannot interpolate non-string values
Title: Message Title Henrik Lindberg commented on HI-599 Re: Hiera cannot interpolate non-string values I could argue that scope should work the same way as alias - it is not backwards compatible though to make such a change as some may rely on it interpolating the variable as a string. I am very reluctant to introduce new interpolation functions (especially when they are not actual string interpolations) and I am also very reluctant to introduce any syntax into the data values used in hiera data. What we could do is to solve this with lookup_options - we have a ticket for a real alias expressed in lookup_options. Would not be terribly hard to also support a variable/dig reference (mutually exclusive with use of alias).

Re: Hiera cannot interpolate non-string values
In a custom backend you can do whatever you want. The lookup_key kind does not automatically perform hira interpolation of the returned values. For a data_hash you would return a hash where the variable reference is already resolved using for example the {[dig}} function to drill down into the value.

Re: Hiera cannot interpolate non-string values
Right, alias does not actually work because that is a lookup in hiera, not a variable reference. The documentation shows that there also is a scope interpolation function (See https://puppet.com/docs/puppet/5.0/hiera_interpolation.html#using-interpolation-functions). Have you tried:
docker::selinux_enabled: "%{scope(facts.selinux.enabled)}"
That seems to be what you are after? Not sure if it retains the data type of the variable though.

Re: Hiera cannot interpolate non-string values
It would be ideal if, instead of overriding particular lookups at the configuration layer, that this could be exposed at interpolation time so that it is less confusing for users. For instance, something like the following would be nice: "%{typed('facts.selinux.enabled', 'Boolean')}"

Hiera cannot interpolate non-string values
Issue Type:
Bug
Assignee:
Unassigned
Created:
2018/04/05 8:43 AM
Priority:
Normal
Reporter:
Carl Caum
It is not possible for Hiera to interpolate non-string values from Facter. For example, the `selinux.enabled` fact has a Boolean value. However, in Hiera you cannot do something like:
docker::selinux_enabled: %{facts.selinux.enabled}
Instead, the user has to quote the facter fact code so it can be interpolated, like this:
docker::selinux_enabled: "%{facts.selinux.enabled}"
which inadvertently casts any non-string values to a string. Example of a user experiencing this problem: https://github.com/puppetlabs/puppetlabs-docker/issues/212
