Hiera YAML含括号内容在Puppet生成Icinga2配置时的引号异常问题

Looks like you're hitting a quirk in how Puppet handles string escaping when generating Icinga2 config from Hiera YAML. The issue here is that your notes field contains parentheses, which throws off Puppet's automatic quoting logic—it incorrectly adds quotes inside the parentheses instead of wrapping the entire string.

Here are a few straightforward fixes to resolve this:

1. Explicitly Quote the notes Field in Hiera #

The simplest solution is to wrap the notes value in double quotes directly in your Hiera YAML. This tells Puppet to treat the entire content as a single string, preventing it from misinterpreting the parentheses:

vars:
  psuName: xxxxx
  liveCustomers: 100
  notes: "some notes here (more info in brackets)"
  uplink: uplink01

When Puppet generates the Icinga2 config, this should produce the correct output:

vars.notes = "some notes here (more info in brackets)"

2. Force Quoting in Your Puppet Template #

If you can't modify the Hiera data (e.g., it's auto-generated), adjust your Puppet ERB template to explicitly wrap the notes variable in quotes. For example:

vars.notes = "<%= @vars['notes'] %>"

If your notes might contain double quotes later, use an escaping method to ensure valid syntax:

vars.notes = "<%= @vars['notes'].escape('json') %>"

This guarantees the entire string is enclosed in quotes, regardless of special characters inside.

3. Check Your Icinga2 Puppet Module #

If you're using a community Puppet module for Icinga2, the automatic quoting logic might have a bug with special characters. Check the module's documentation to see if there's a parameter or setting to enforce consistent string quoting, or consider filing an issue with the module maintainers if this is a recurring problem.
