Use eyaml to decrypt secret values
==================================
Prerequisites
-------------
#. Install eyaml and create keys (All of this should be done on the slave server)
.. code-block:: bash
$ sudo yum install ruby-gems || sudo apt-get install ruby
$ sudo gem install hiera-eyaml
$ eyaml createkeys
#. Move keys to /etc/eyaml_keys
.. code-block:: bash
$ sudo mkdir -p /etc/eyaml_keys/
$ sudo mv ./keys/* /etc/eyaml_keys/
#. Set up eyaml config.yaml
.. code-block:: bash
$ mkdir ~/.eyaml/
$ cp config.yaml.example ~/.eyaml/config.yaml
Encryption
----------
#. Copy a PDF (yaml) to current directory (or edit the PDF in-place)
NOTE: There is a sample encrypted PDF located at `../pdf/pod1.encrypted.yaml`.
Data in that file is only an example and can't be decrypted without the PEM,
which is not provided.
.. code-block:: bash
$ cp ~/foo/securedlab/labs/lf/pod2.yaml .
#. Create some encrypted values
.. code-block:: bash
$ eyaml encrypt -s 'opnfv'
#. Replace values to be encrypted
.. code-block:: yaml
type: ipmi
versions:
- 2.0
user: ENC[PKCS7 ...]
pass: ENC[PKCS7 ...]
Decryption
----------
.. code-block:: bash
$ ./generate_config.py -y pod2.yaml -j ../installers/apex/pod_config.yaml.j2
