Vault

This Ansible role performs a basic Vault installation, including filesystem structure and example configuration.

It can also bootstrap a minimal development or evaluation server or HA Consul-backed cluster in a Vagrant and VirtualBox based environment. See README_VAGRANT.md and the associated Vagrantfile for more details about the developer mode setup.

Installation

Brian Shumates transferred this role to @ansible-community/hashicorp-tools. This role resides on GitHub pending fixing the integration with Ansible Galaxy. To install this role create a roles/requirements.yml file in your Ansible project folder with the following contents:

- src: https://github.com/ansible-community/ansible-vault.git
  name: ansible-community.ansible-vault
  scm: git
  version: master

You can use git tag in the version attribute. Also you can honor its legacy name: brianshumate.ansible-vault.

Requirements

This role requires Archlinux, or FreeBSD, or a Debian or RHEL based Linux distribution. It might work with other software versions, but does work with the following specific software and versions:

Ansible: 2.8.4
Vault: 1.4.0 and above
Debian
- Debian 10 (buster)
- Debian 9 (stretch)
- Debian 8 (jessie)
FreeBSD 11
Ubuntu 18.04, 20.04
ArchLinux

Sorry, there is no planned support at the moment for Windows.

Warning

By default, this role may restart vault service when played (when there's a configuration change, OS Packages installed/updated)

When there's no auto-unseal setup on your cluster, the restart may lead to a situation where all Vault instances will be sealed and your cluster will be down.

To avoid this situation, the service restart by the playbook can be disabled by using the vault_service_restart role variable.

Setting this vault_service_restart to false will disable the vault service restart by the playbook. You may have to restart the service manually to load any new configuration deployed.

Dependencies

NOTE: Read these before executing the role to avoid certain frequently encountered issues which are resolved by installing the correct dependencies.

`gtar`

Ansible requires GNU tar and this role performs some local use of the unarchive module, so ensure that your system has gtar installed.

Python netaddr

The role depends on python-netaddr so:

pip install netaddr

on the Ansible control host prior to executing the role.

Example Playbook

Basic installation is possible using the included site.yml playbook:

ansible-playbook -i hosts site.yml

You can also pass variables in using the --extra-vars option to the ansible-playbook command:

ansible-playbook -i hosts site.yml --extra-vars "vault_datacenter=maui"

Specify a template file with a different backend definition (see templates/backend_consul.j2):

ansible-playbook -i hosts site.yml --extra-vars "vault_backend_file=backend_file.j2"

You need to make sure that the template file backend_file.j2 is in the role directory for this to work.

Vagrant and VirtualBox

See examples/README_VAGRANT.md for details on quick Vagrant deployments under VirtualBox for testing, etc.

example virtualBox playbook
