Vault Pillar Module

maintainer:SaltStack
maturity:New
platform:all

New in version 2016.11.0.

This module allows pillar data to be stored in Hashicorp Vault.

Base configuration instructions are documented in the execution module docs. 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.

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

$ 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:

$ salt-ssh '*' pillar.get auth

Multiple Vault sources may also be used:

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.

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

#Nesting Key not defined

    salt-passwd:
        badpasswd1
    root-passwd:

    minion-passwd:

            root-passwd:
                rootbadpasswd1
    keyname2:
        ----------
            minion-passwd:
                minionbadpasswd1
