puppet apply and hiera data?

I want to test out my puppet code and hiera data. Specifically, I need to see what would the contents of my ceilometer.conf be given a certain set of data in my hiera data.

So I have:

[root@vm-red modules]# tree
├── ceilometer
│   ├── manifests
│   │   └── controller.pp
│   └── templates
│       ├── ceilometer_conf.erb
│       ├── pipeline_yaml.erb
│       ├── policy_json.erb
│       └── sources_json.erb
└── controller
    └── manifests
        └── init.pp

5 directories, 7 files

I copied my hiera data to the /var/lib/hiera/defaults.yaml file. Here's the pertinent parameters used by my controller class:

    [root@vm-red modules]# grep "^ceilometer" /var/lib/hiera/defaults.yaml
    ceilometer_admin_password: "fakepass"
    ceilometer_admin_user: "ceilometer"
    ceilometer_db_host: ""
    ceilometer_db_name: "my_os_ceilo"
    ceilometer_db_pass: "fakepass"
    ceilometer_db_user: "my_os_ceilo"
    ceilometer_os_password: "fakepass"
    ceilometer_os_tenant_name: "services"
    ceilometer_os_username: "ceilometer"
    ceilometer_mongodb_dbname: "%{hiera('ceilometer_db_name')}"
    ceilometer_mongodb_pass: "%{hiera('ceilometer_db_pass')}"
    ceilometer_mongodb_user: "%{hiera('ceilometer_db_user')}"

    [root@vm-red modules]# grep controller::ceilometer /var/lib/hiera/defaults.yaml
    controller::ceilometer_admin_password: "%{hiera('ceilometer_admin_password')}"
    controller::ceilometer_admin_user: "%{hiera('ceilometer_admin_user')}"
    controller::ceilometer_db_host: "%{hiera('ceilometer_db_host')}"
    controller::ceilometer_db_name: "%{hiera('ceilometer_db_name')}"
    controller::ceilometer_db_pass: "%{hiera('ceilometer_db_pass')}"
    controller::ceilometer_db_user: "%{hiera('ceilometer_db_user')}"
    controller::ceilometer_os_auth_url: "https://%{hiera('controller_vip_name')}:35357/v2.0"
    controller::ceilometer_os_password: "%{hiera('ceilometer_os_password')}"
    controller::ceilometer_os_tenant_name: services
    controller::ceilometer_os_username: "%{hiera('ceilometer_mongodb_user')}"

My hiera.yaml is just the default one:

# cat /etc/puppetlabs/puppet/hiera.yaml 
  - yaml
  - defaults
  - "%{clientcert}"
  - "%{environment}"
  - global

# datadir is empty here, so hiera uses its defaults:
# - /var/lib/hiera on *nix
# - %CommonAppData%\PuppetLabs\hiera\var on Windows
# When specifying a datadir, make sure the directory exists.

But when I run my puppet apply like so ...

# puppet apply --hiera_config=/etc/puppetlabs/puppet/hiera.yaml --modulepath=`pwd`/modules -e 'include controller'
Notice: Compiled catalog for in environment production in 0.14 seconds
Notice: /Stage[main]/Ceilometer::Controller/File[/tmp/ceilometer.conf]/ensure: defined content as '{md5}eee090956a2ac49c98d49fca222779bd'
Notice: Finished catalog run in 0.24 seconds

the file /tmp/ceilometer.conf does not have any of the hiera data in it!

# head /tmp/ceilometer.conf 
connection = mongodb://:@:27017/

Here's part of the template file I am using:

# cat modules/ceilometer/templates/ceilometer_conf.erb 
connection = mongodb://<%= @ceilometer_db_user %>:<%= @ceilometer_db_pass %>@<%= @mongo_db_host %>:27017/<%= @ceilometer_db_name %>

Could someone point out what I am doing wrong? Is it that puppet apply just does work with hiera?

In your manifest how did you retrieve the value of that particular parameters that you interpolate on template?

Did you do a $ceilometer_db_user = hiera('ceilometer_db_user')?

Doh! I took a look at my `controller` class's `init.pp` file and I see I neglected to add the list of parameters. You know all the stuff between `class controller (` and `) {`. Thanks for getting me to the solution. :)
