How to create secured files in Puppet5 with Hiera? - puppet

Question

I want to create SSL certificate and try to secure this operation.
I am using Puppet 5.5.2 and gem hiera-eyaml.
Created simple manifest
cat /etc/puppetlabs/code/environments/production/manifests/site.pp
package { 'tree':
ensure => installed,
}
package { 'httpd':
ensure => installed,
}
$filecrt = lookup('files')
create_resources( 'file', $filecrt )
Hiera config
---
version: 5
defaults:
# The default value for "datadir" is "data" under the same directory as the hiera.yaml
# file (this file)
# When specifying a datadir, make sure the directory exists.
# See https://puppet.com/docs/puppet/latest/environments_about.html for further details on environments.
datadir: data
data_hash: yaml_data
hierarchy:
- name: "Secret data: per-node, per-datacenter, common"
lookup_key: eyaml_lookup_key # eyaml backend
paths:
- "nodes/%{facts.fqdn}.eyaml"
- "nodes/%{trusted.certname}.eyaml" # Include explicit file extension
- "location/%{facts.whereami}.eyaml"
- "common.eyaml"
options:
pkcs7_private_key: /etc/puppetlabs/puppet/eyaml/keys/private_key.pkcs7.pem
pkcs7_public_key: /etc/puppetlabs/puppet/eyaml/keys/public_key.pkcs7.pem
- name: "YAML hierarchy levels"
paths:
- "common.yaml"
- "nodes/%{facts.fqdn}.yaml"
- "nodes/%{::trusted.certname}.yaml"
And common.yaml
---
files:
'/etc/httpd/conf/server.crt':
ensure: present
mode: '0600'
owner: 'root'
group: 'root'
content: 'ENC[PKCS7,{LOT_OF_STRING_SKIPPED}+uaCmcHgDAzsPD51soM+AIkIlv0ANpUXzBpwM3tqQ3ysFtz81S0xuVbKvslK]'
But have en error while applying manifest
Error: Evaluation Error: Error while evaluating a Function Call, create_resources(): second argument must be a hash (file: /etc/puppetlabs/code/environments/production/manifests/site.pp, line: 12, column: 1) on node test1.com
I really dont know what to do )

Answer 1

The problem appears to be that the indentation in common.yaml isn't right - currently, file will be null rather than a hash, which explains the error message. Also, the file should be called common.eyaml, otherwise the ENC string won't be decrypted. Try
---
files:
'/etc/httpd/conf/server.crt':
ensure: present
mode: '0600'
owner: 'root'
group: 'root'
content: 'ENC[PKCS7{LOTS_OF_STRING_SKIPPED}UXzBpwM3tqQ3ysFtz81S0xuVbKvslK]'
There is an online YAML parser at http://yaml-online-parser.appspot.com/ if you want to see the difference the indentation makes.

Answer 2

Found another solution.
Its was a problem with lookup and hashes. When I have multiply lines in hiera hash, I must specify them https://docs.puppet.com/puppet/4.5/function.html#lookup
So i decided use only 'content' variable to lookup
cat site.pp
$filecrt = lookup('files')
file { 'server.crt':
ensure => present,
path => '/etc/httpd/conf/server.crt',
content => $filecrt,
owner => 'root',
group => 'root',
mode => '0600',
}
and Hiera
