So I have used the built in JSON backend which makes it easy to validate a
json file using any number of tools.
However, some of my clients prefer the default hiera yaml backend which
there is no tool to validate basic parameter values being dumped into a
hiera file, and YAML.load_file is essentially useless as a validator.
For reference:
https://github.com/gds-operations/puppet-syntax/issues/39
Things I want to check are that the user supplied the necessary syntax to
create a list, hash or other data types in yaml much like the JSON
equivalent. The difference being that JSON is a subset of YAML and by
default comes with its own validator (afaik). Since the YAML parser is so
generic I figured that puppetlabs might have already created a Kwalify
schema to validate hiera files that use the yaml backend.
I have come across a few situations where if the user fat fingers
characters into the hiera files, all hell breaks loose because the YAML
parser really doesn't care whats in the file and keys are never found.
Example:
---
{}
fsdafsdone::two::three: some_value
hiera('one::two::three') will never return some_value.

Hi,
Has anybody created a yaml Kwalify schema for hiera files. I would like
to validate my yaml files against an official hiera schema using Kwalify.
Since the YAML spec varies greatly a schema is required to validate hiera
specific keys.
Exactly which hiera files do you mean?
The format is very much up to the implementation of a particular backend.
I also wonder if what you are trying to achieve is possible to check
with Kwalify - I expect it to load the yaml using a yaml implementation,
and thus any lexical problems in your yaml files have already occured
due to differences in yaml implementations.
The result could still be valid - only not what you intended.
This lexical problem is different than validating that the structural
content follows a particular yaml schema.
