Ansible Modules Hashivault

Ansible modules for Hashicorp Vault.

Install this Ansible module:

• via pip:

pip install ansible-modules-hashivault

• via ansible-galaxy (requires hvac>=0.7.0):

ansible-galaxy install 'git+https://github.com/TerryHowe/ansible-modules-hashivault.git'

Note: The hashicorp lookup plugin does not work with this last install method (ansible/ansible#28770). You can fallback to the build-in lookup plugin: hashi_vault

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

Environmental Variables

The following variables need to be exported to the environment where you run ansible in order to authenticate to your HashiCorp Vault instance:

• VAULT_ADDR: url for vault
• VAULT_SKIP_VERIFY=true: if set, do not verify presented TLS certificate before communicating with Vault server. Setting this variable is not recommended except during testing
• VAULT_AUTHTYPE: authentication type to use: token, userpass, github, ldap, approle
• VAULT_TOKEN: token for vault
• VAULT_ROLE_ID: (required by approle)
• VAULT_SECRET_ID: (required by approle)
• VAULT_USER: username to login to vault
• VAULT_PASSWORD: password to login to vault
• VAULT_CLIENT_KEY: path to an unencrypted PEM-encoded private key matching the client certificate
• VAULT_CLIENT_CERT: path to a PEM-encoded client certificate for TLS authentication to the Vault server
• VAULT_CACERT: path to a PEM-encoded CA cert file to use to verify the Vault server TLS certificate
• VAULT_CAPATH: path to a directory of PEM-encoded CA cert files to verify the Vault server TLS certificate
• VAULT_NAMESPACE: specify the Vault Namespace, if you have one

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

Ansible does not handle binary data well, so these modules are provided for convenience to read/write files:

---
- hashivault_read_to_file:
    secret: 'ssl_certs'
    key: 'der_format'
    dest: 'ssl_cert.cer'
- hashivault_write_from_file:
    secret: 'ssl_certs'
    key: 'der_format'
    path: 'ssl_cert.cer'

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'

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
