Ansible module for Hashicorp Vault.

Ansible Modules Hashivault

Ansible modules for Hashicorp Vault.

In most cases the Hashicorp Vault modules should be run on localhost.

Reading and Writing

The following example writes the giant secret with two values and then reads the fie value:

---
- hosts: localhost
  vars:
    foo_value: 'fum'
    fie_value: 'fum'
  tasks:
    - hashivault_status:
      register: 'vault_status'
    - hashivault_write:
        secret: 'giant'
        data:
            foo: '{{foo_value}}'
            fie: '{{fie_value}}'
      register: 'vault_write'
    - hashivault_read:
        secret: 'giant'
        key: 'fie'
      register: 'vault_read'

The lookup plugin:

looky: "{{lookup('hashivault', 'giant', 'foo')}}"

By default, the hashivault_write, hashivault_read and the lookup plugin assume the /secret mount point. If you are accessing another mount point, start the secret with a '/':

---
- hosts: localhost
  tasks:
    - hashivault_write:
        secret: '/stories/stuart'
        data:
            last: 'little'
    - hashivault_read:
        secret: '/stories/charlotte'
        key: 'web'
    - set_fact:
        book: "{{lookup('hashivault', '/stories/charlotte', 'web')}}"

Get a list of secrets:

---
- hosts: localhost
  tasks:
    - hashivault_list:
        secret: '/stories'
      register: vault

Initialization, Seal, and Unseal

You may init the vault:

---
- hosts: localhost
  tasks:
    - hashivault_init:
      register: 'vault_init'

You may also seal and unseal the vault:

---
- hosts: localhost
  vars:
    vault_keys:  "{{ lookup('env','VAULT_KEYS') }}"
  tasks:
    - hashivault_status:
      register: 'vault_status'
    - block:
        - hashivault_seal:
          register: 'vault_seal'
      when: "{{vault_status.status.sealed}} == False"
    - hashivault_unseal:
        keys: '{{vault_keys}}'

Policy

Policy support:

---
- hosts: localhost
  vars:
    name: 'terry'
    rules: >
        path "secret/{{name}}/*" {
          capabilities = ["create", "read", "update", "delete", "list"]
        }
        path "secret/{{name}}" {
          capabilities = ["list"]
        }
  tasks:
    - hashivault_policy_set:
        name: "{{name}}"
        rules: "{{rules}}"
      register: 'vault_policy_set'
    - hashivault_policy_get:
        name: '{{name}}'
      register: 'vault_policy_get'
    - hashivault_policy_list:
      register: 'vault_policy_list'

User Management

Add and delete users for userpass:

---
- hosts: localhost
  vars:
    username: 'portugal'
    userpass: 'Th3m@n!!'
  tasks:
    - hashivault_userpass_create:
        name: "{{username}}"
        pass: "{{userpass}}"
        policies: "{{username}}"
      register: 'vault_userpass_create'

    - hashivault_userpass_delete:
        name: "{{username}}"
      register: 'vault_userpass_delete'

Authentication Backends

Handle auth backends:

---
- hosts: localhost
  tasks:
    - hashivault_auth_list:
      register: 'vault_auth_list'
    - block:
      - hashivault_auth_enable:
          name: "userpass"
        register: 'vault_auth_enable'
      when: "'userpass/' not in vault_auth_list.backends"

Audit Backends

Handle audit backends:

---
- hosts: localhost
  tasks:
    - hashivault_audit_list:
      register: 'vault_audit_list'
    - block:
      - hashivault_audit_enable:
          name: "syslog"
        register: 'vault_audit_enable'
      when: "'syslog/' not in vault_audit_list.backends"

Rekey Vault

Various rekey vault operations:

---
- hashivault_rekey_init:
    secret_shares: 7
    secret_threshold: 4
- hashivault_rekey:
  key: '{{vault_key}}'
  nonce: '{{nonce}}'
- hashivault_rekey_status:
  register: "vault_rekey_status"
- hashivault_rekey_cancel:
  register: "vault_rekey_cancel"

Secret Backends

Enable and disable various secret backends:

---
- hashivault_secret_list:
  register: 'hashivault_secret_list'
- hashivault_secret_enable:
    name: "ephemeral"
    backend: "generic"
- hashivault_secret_disable:
    name: "ephemeral"
    backend: "generic"

Token Manipulation

Various token manipulation modules:

---
- hashivault_token_create:
    display_name: "syadm"
    policies: ["sysadm"]
    renewable: True
    token: "{{vault_root_token}}"
  register: "vault_token_admin"
- hashivault_token_lookup:
    lookup_token: "{{client_token}}"
  register: "vault_token_lookup"

Action Plugin

If you are not using the VAULT_ADDR and VAULT_TOKEN environment variables, you may be able to simplify your playbooks with an action plugin. This can be some somewhat similar to this example action plugin.

Developer Note

One of the complicated problems with development and testing of this module is ansible/module_utils/hashivault.py is not a directory in itself which in my opinion is a problem with ansible. Because of this limitation with ansible, pip install -e . does not work like it would for other projects. Two potential ways to work around this issue are either use the link.sh script in the top level directory or run for every change:

rm -rf dist; python setup.py sdist
pip install ./dist/ansible-modules-hashivault-*.tar.gz
