url
Url to your Vault installation. Required.
verify
For details please see
http://docs.python-requests.org/en/master/user/advanced/#ssl-cert-verification
.. versionadded:: 2018.3.0
role_name
Role name for minion tokens created. If omitted, minion tokens will be
created without any role, thus being able to inherit any master token
policy (including token creation capabilities). Optional.
For details please see:
https://www.vaultproject.io/api/auth/token/index.html#create-token
Example configuration:
https://www.nomadproject.io/docs/vault-integration/index.html#vault-token-role-configuration
auth
Currently only token and approle auth types are supported. Required.
Approle is the preferred way to authenticate with Vault as it provide
some advanced options to control authentication process.
Please visit Vault documentation for more info:
https://www.vaultproject.io/docs/auth/approle.html
The token must be able to create tokens with the policies that should be
assigned to minions.
You can still use the token auth via a OS environment variable via this
config example:
.. code-block: yaml
vault:
url: https://vault.service.domain:8200
auth:
method: token
token: sdb://osenv/VAULT_TOKEN
osenv:
driver: env
And then export the VAULT_TOKEN variable in your OS:
.. code-block: bash
export VAULT_TOKEN=11111111-1111-1111-1111-1111111111111
policies
Policies that are assigned to minions when requesting a token. These can
either be static, eg saltstack/minions, or templated, eg
``saltstack/minion/{minion}``. ``{minion}`` is shorthand for grains[id].
Grains are also available, for example like this:
``my-policies/{grains[os]}``
If a template contains a grain which evaluates to a list, it will be
expanded into multiple policies. For example, given the template
``saltstack/by-role/{grains[roles]}``, and a minion having these grains:
.. code-block: yaml
grains:
roles:
- web
- database
The minion will have the policies ``saltstack/by-role/web`` and
``saltstack/by-role/database``. Note however that list members which do
not have simple string representations, such as dictionaries or objects,
do not work and will throw an exception. Strings and numbers are
examples of types which work well.
Optional. If policies is not configured, ``saltstack/minions`` and
``saltstack/{minion}`` are used as defaults.
keys
List of keys to use to unseal vault server with the vault.unseal runner.
