I'm still setting up my new PE 2016.4 installation and I'm running into
a problem with Hiera data per environment. I followed these steps:
https://docs.puppet.com/puppet/4.7/reference/lookup_quick.html#if-you-already-use-hiera-in-environments
Every Puppet run errors with:
Error: Could not retrieve catalog from remote server: Error 500 on
SERVER: Server Error: Evaluation Error: Error while evaluating a
Function Call, Lookup of key 'classes' failed: Cannot load backend
module_data: no such file to load -- hiera/backend/module_data_backend
in Cannot load backend module_data: no such file to load --
hiera/backend/module_data_backend at
/etc/puppetlabs/code/environments/pe/manifests/site.pp:32:1 on node
puppet4-prod.resnet.bris.ac.uk
site.pp:32 contains:
lookup('classes', Array[String], 'unique').include
My per-environment hiera.yaml contains:
---
version: 4
datadir: data
hierarchy:
- name: "Nodes"
backend: yaml
path: "node/%{trusted.certname}"
- name: "Operating System"
backend: yaml
path: "operatingsystem/%{operatingsystem}"
- name: "Operaring System Release"
backend: yaml
path: "operatingsystem/%{operatingsystem}/%{operatingsystemmajrelease}"
- name: "Virtual"
backend: yaml
path: "virtual/%{virtual}"
- name: "Manufacturer"
backend: yaml
path: "manufacturer/%{manufacturer}"
- name: "Module"
backend: yaml
path: "module/%{calling_module}"
- name: "Common"
backend: yaml
path: "common"
The file data/node/puppet4-prod.resnet.bris.ac.uk.yaml contains:
---
classes:
- 'uob_pe'
So there should definitely be a value for "classes". I tried a command
to give some debug output:
[root@puppet4-prod ~]# puppet lookup classes --node
puppet4-prod.resnet.bris.ac.uk --explain
Error: Could not run: Evaluation Error: Error while evaluating a
Resource Statement, Evaluation Error: Error while evaluating a Method
call, 'dig' parameter 'data' expects a Collection value, got String at
/opt/puppetlabs/puppet/modules/puppet_enterprise/manifests/master/puppetserver.pp:673:42
That manifest ships with PE and I haven't messed with it. Anyone know
what's going on?
Thanks!
