Eyaml hiera configuration for puppet, as promised

Morning,

We managed to configure also the hiera backend in order to have eyaml module active. It is related to the following past article http://log-it.tech/2017/05/29/install-eyaml-module-on-puppet-master/. So in the hiera.yaml you bassicaly need to add the following configuration before hierarchy:

:backends:
  - eyaml
  - yaml
  - puppetdb

and

:eyaml:
    :datadir: /etc/puppetlabs/hieradata
    :pkcs7_private_key: /etc/puppetlabs/puppet/eyaml/private_key.pkcs7.pem
    :pkcs7_public_key:  /etc/puppetlabs/puppet/eyaml/public_key.pkcs7.pem 
    :extension: 'yaml

at the botton. After this is done, the most essential part is that you created the required symlinks so that the backend is enabled.
This should be done easily with a bash script like:

#!/bin/bash
ln -s /opt/puppetlabs/puppet/lib/ruby/gems/2.1.0/gems/hiera-eyaml-2.1.0/lib/hiera/backend/eyaml /opt/puppetlabs/puppet/lib/ruby/vendor_ruby/hiera/backend/eyaml
ln -s /opt/puppetlabs/puppet/lib/ruby/gems/2.1.0/gems/hiera-eyaml-2.1.0/lib/hiera/backend/eyaml_backend.rb /opt/puppetlabs/puppet/lib/ruby/vendor_ruby/hiera/backend/eyaml_backend.rb
ln -s /opt/puppetlabs/puppet/lib/ruby/gems/2.1.0/gems/hiera-eyaml-2.1.0/lib/hiera/backend/eyaml.rb /opt/puppetlabs/puppet/lib/ruby/vendor_ruby/hiera/backend/eyaml.rb
ln -s /opt/puppetlabs/puppet/lib/ruby/gems/2.1.0/gems/highline-1.6.21/lib/highline /opt/puppetlabs/puppet/lib/ruby/vendor_ruby/highline/
ln -s /opt/puppetlabs/puppet/lib/ruby/gems/2.1.0/gems/highline-1.6.21/lib/highline.rb /opt/puppetlabs/puppet/lib/ruby/vendor_ruby/highline.rb

After this is done, it is advised for a puppetdb and puppetserver restart, and you can try testing it by putting a string in hiera and see if a notice prints the required output. Something like

profiles::test::teststring: '[string generated with eyaml ecrypt -s 'test']'

and then creating a small class like :


class profiles::test{
$teststring = hiera('profiles::test::teststring')
notice {"${teststring}":}
}

That should be most of you need in order to do this. Hope it works! ­čÖé

Cheers!

Install eyaml module on puppet master

Hi,

Today i will show how i installed module used for data encrypt in order to safely include it in hiera yaml files)
It really simple as described on https://github.com/voxpupuli/hiera-eyaml. The actual step that i couldn’t find explicitly written in the doku and i had to figure it out myself is that you need to modify the┬áconfig.yaml needed by the module.

  1. gem install hiera-eyaml
  2. puppetserver gem install hiera-eyaml
  3. eyaml createkeys
  4. mv ./keys /etc/puppetlabs/puppet/eyaml
  5. $ chown -R puppet:puppet /etc/puppetlabs/puppet/eyaml
    $ chmod -R 0500 /etc/puppetlabs/puppet/eyaml
    $ chmod 0400 /etc/puppetlabs/puppet/eyaml/*.pem
    $ ls -lha /etc/puppetlabs/puppet/eyaml
    -r——– 1 puppet puppet 1.7K Sep 24 16:24 private_key.pkcs7.pem
    -r——– 1 puppet puppet 1.1K Sep 24 16:24 public_key.pkcs7.pem
  6.  vim /etc/eyaml/config.yaml and add following content:
    ---
    pkcs7_private_key: '/etc/puppetlabs/puppet/eyaml/private_key.pkcs7.pem'
    pkcs7_public_key: '/etc/puppetlabs/puppet/eyaml/public_key.pkcs7.pem'

If the last step is not executed, you will get the error:┬á[hiera-eyaml-core] No such file or directory – ./keys/public_key.pkcs7.pem

After these configurations you should be able to encrypt files or strings. Short example:

eyaml encrypt -s 'test'
[hiera-eyaml-core] Loaded config from /etc/eyaml/config.yaml
string: ENC[PKCS7,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]

Will write something similar for Hiera configuration to use the desired backend.

Cheers!
