configuration:

The salt-master must be configured to allow peer-runner configuration, as well as configuration for the module.

Add this segment to the master configuration file, or /etc/salt/master.d/vault.conf:

vault:
    url: https://vault.service.domain:8200
    verify: /etc/ssl/certs/ca-certificates.crt
    role_name: minion_role
    auth:
        method: approle
        role_id: 11111111-2222-3333-4444-1111111111111
        secret_id: 11111111-1111-1111-1111-1111111111111
    policies:
        - saltstack/minions
        - saltstack/minion/{minion}
        .. more policies

        - 3pPK5X6vGtwLhNOFv1U2elahECz3HpRUfNXJFYLw6lid
url

Url to your Vault installation. Required.

verify

For details please see http://docs.python-requests.org/en/master/user/advanced/#ssl-cert-verification

New in version 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:

And then export the VAULT_TOKEN variable in your OS:

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:

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.

Add this segment to the master configuration file, or /etc/salt/master.d/peer_run.conf:

peer_run:
    .*:
        - vault.generate_token

salt.modules.vault.delete_secret(path)

Delete secret at the path in vault. The vault policy used must allow this.

CLI Example:

salt '*' vault.delete_secret "secret/my/secret"

salt.modules.vault.list_secrets(path)

List secret keys at the path in vault. The vault policy used must allow this. The path should end with a trailing slash.

CLI Example:

salt '*' vault.list_secrets "secret/my/"

salt.modules.vault.read_secret(path, key=None)

Return the value of key at path in vault, or entire secret

Jinja Example:

my-secret: {{ salt['vault'].read_secret('secret/my/secret', 'some-key') }}
{% set supersecret = salt['vault'].read_secret('secret/my/secret') %}
secrets:
    first: {{ supersecret.first }}
    second: {{ supersecret.second }}

salt.modules.vault.write_raw(path, raw)

Set raw data at the path in vault. The vault policy used must allow this.

CLI Example:

salt '*' vault.write_raw "secret/my/secret" '{"user":"foo","password": "bar"}'

salt.modules.vault.write_secret(path, **kwargs)

Set secret at the path in vault. The vault policy used must allow this.

CLI Example:

salt '*' vault.write_secret "secret/my/secret" user="foo" password="bar"
