Vault Pillar Module
:maintainer: SaltStack
:maturity: New
:platform: all
.. versionadded:: 2016.11.0
This module allows pillar data to be stored in Hashicorp Vault.
Base configuration instructions are documented in the :ref:`execution module docs <vault-setup>`.
Below are noted extra configuration required for the pillar module, but the base
configuration must also be completed.
After the base Vault configuration is created, add the configuration below to
the ext_pillar section in the Salt master configuration.
.. code-block:: yaml
ext_pillar:
- vault: path=secret/salt
Each key needs to have all the key-value pairs with the names you
require. Avoid naming every key 'password' as you they will collide:
If you want to nest results under a nesting_key name use the following format:
ext_pillar:
- vault:
conf: path=secret/salt
nesting_key: vault_key_name
.. code-block:: bash
$ vault write secret/salt auth=my_password master=127.0.0.1
The above will result in two pillars being available, ``auth`` and ``master``.
You can then use normal pillar requests to get each key pair directly from
pillar root. Example:
.. code-block:: bash
$ salt-ssh '*' pillar.get auth
Multiple Vault sources may also be used:
.. code-block:: yaml
ext_pillar:
- vault: path=secret/salt
- vault: path=secret/root
- vault: path=secret/minions/{minion}/pass
You can also use nesting here as well. Identical nesting keys will get merged.
.. code-block:: yaml
ext_pillar:
- vault:
conf: path=secret/salt
nesting_key: keyname1
- vault:
conf: path=secret/root
nesting_key: keyname1
- vault:
conf: path=secret/minions/{minion}/pass
nesting_key: keyname2
The difference between the return with and without the nesting key is shown below.
This example takes the key value pairs returned from vault as follows:
path=secret/salt
Key Value
--- -----
salt-passwd badpasswd1
path=secret/root
Key Value
--- -----
root-passwd rootbadpasswd1
path=secret/minions/{minion}/pass
Key Value
--- -----
minion-passwd minionbadpasswd1
.. code-block:: yaml
#Nesting Key not defined
local:
----------
salt-passwd:
badpasswd1
root-passwd:
rootbadpasswd1
minion-passwd:
minionbadpasswd1
#Nesting Key defined
local:
----------
keyname1:
----------
salt-passwd:
badpasswd1
root-passwd:
rootbadpasswd1
keyname2:
----------
minion-passwd:
minionbadpasswd1
