Vault

Build Status Ansible Galaxy Average time to resolve an issue Percentage of issues still open

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.

Requirements

This role requires 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: 2.4.2.0
  • Vault: 0.9.1
  • Debian: 8
  • FreeBSD 11
  • Ubuntu 16.04

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

OS Distribution Variables

The consul binary works on most Linux platforms and is not distribution specific. However, some distributions require installation of specific OS packages with different naming, so this role was built with support for popular Linux distributions and defines these variables to deal with the differences across distributions:

vault_pkg

  • Vault package filename
  • Default value: {{ vault_version }}_linux_amd64.zip

vault_centos_url

  • Vault package download URL
  • Default value: {{ vault_zip_url }}

vault_centos_os_packages

  • List of OS packages to install
  • Default value: list

vault_pkg

  • Vault package filename
  • Default value: "{{ vault_version }}_linux_amd64.zip"

vault_debian_url

  • Vault package download URL
  • Default value: "{{ vault_zip_url }}"

vault_sha256

  • Vault download SHA256 summary
  • Default value: SHA256 SUM

vault_debian_os_packages

  • List of OS packages to install
  • Default value: list

vault_pkg

  • Vault package filename
  • Default value: "{{ vault_version }}_linux_amd64.zip"

vault_redhat_url

  • Vault package download URL
  • Default value: "{{ vault_zip_url }}"

vault_sha256

  • Vault package SHA256 summary
  • Default value: SHA256 SUM

vault_redhat_os_packages

  • List of OS packages to install
  • Default value: list

vault_pkg

  • Vault package filename
  • Default value: "{{ vault_version }}_linux_amd64.zip"

vault_ubuntu_url

  • Vault package download URL
  • Default value: "{{ vault_zip_url }}"

vault_sha256

  • Vault package SHA256 summary
  • Default value: SHA256 SUM

vault_ubuntu_os_packages

  • List of OS packages to install
  • Default value: list

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_backed=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.

Vault Enterprise

The role can install Vault Enterprise based instances.

Place the Vault Enterprise zip archive into {{ role_path }}/files and set vault_enterprise: true or use the VAULT_ENTERPRISE="true" environment variable.

Aditionaly enable or disable the UI with the vault_enterprise_ui option (default true).
