Introduction To Ansible Vault

Hi readers, in this blog we will be discussing Ansible vault. Also, we will be looking at how to encrypt different playbooks and how they can be decrypted.

Introduction

The “Vault” is a feature of Ansible that allows you to keep sensitive data such as passwords or keys protected at rest, rather than as plain text in playbooks or roles.

Why use Ansible Vault?

Ansible is used for automation, the playbooks contain certain credentials, SSL certificates ,or other sensitive data. Usually, we store our sensitive data in the variable of vault.

How Ansible Vault help us?

It helps us to encrypt or decrypt sensitive variables that contain information and there are 2 ways to take care of sensitive data :

  1. encrypt variables and embed them into the playbook.

  2. encrypt the entire playbook.

Creating an Encrypted File

To create an encrypted file, use the ansible-vault to create command ,and enter the filename.

When prompted, create a password and then confirm it by re-typing it.

$ ansible-vault create example.yml 
New Vault password: 
Confirm New Vault password: 

After confirming our password, a new file is created and will open an editing window. By default, the editor for Vault is vi. Also, we can add data, save ,and exit.

we can see out newly created file

$ cat example.yml 
$ANSIBLE_VAULT;1.1;AES256
39386238346630643735373664346130303866386233366364336633316237393764393465616362

Encrypting Unencrypted Files

Suppose we have a file which we wish to encrypt, we can use the ansible-vault encrypt command.

$ ansible-vault encrypt oldfile.yml
New Vault password: 
Confirm New Vault password: 

Then, you will be prompted to insert and confirm the password after then your file is encrypted.

Editing Encrypted Files

If we want to edit our encrypted file, we can edit it using ansible-vault edit command.

$ ansible-vault edit example.yml 
Vault password:

Viewing Encrypted File

If we want to view our encrypted file, we can use the ansible-vault view command.

 ansible-vault view example.yml
Vault password: 
- name: mukesh
  hosts: WORKSPACE
  tasks:
    - name: copying a file.
      copy:
        src: /home/knoldus/example.yml
        dest: /home/

Rekeying Vault Password

Also, we can change the vault password for which we can use the **ansible-vault rekey **command.

decrypt

We will be prompted with the vault’s current password and then we will add a new password and finally confirming the new password.

Decrypting Encrypted Files

If we want to decrypt an encrypted file, we can use ansible-vault decrypt command. Then, we will be prompted to insert the vault password.

$ ansible-vault decrypt example.yaml 
Vault password: 
Decryption successful

Securing your secrets using vault in Kubernetes — Part 2

In Part 1 of this series, we have learned how to Install Vault-k8s and enable the Kubernetes Auth Mechanism. In this tutorial let’s learn how automatically inject these secrets into our Kubernetes Deployments/Pods.

I have used Helm to create the manifests files. Helm charts are easier to create, version, share, and publish. Copying-and-Pasting the same manifests across multiple environments can be avoided and the same charts can be re-used by maintaining a different final overrides file.

Securing your secrets using vault-k8s in Kubernetes — Part 1

Kubernetes secrets let you store and manage sensitive data such as passwords, ssh keys, Tls certificates, etc. However, there are few limitations to using the build-in secret management for Kubernetes. So, we often tend to rely on some third-party tools to handle secret management. One such tool is HashiCorp Vault. In this series of articles let’s learn to secure our secrets using HashiCorp Vault-k8s in Kubernetes.

Ansible Installation & Configuration on AWS

In this video you will learn Ansible Installation & Configuration on AWS and how to install & configure ansible on ec2 step by step.

Why DevOps is important?

DevOps implementation is going through the roof with most of the largest software organizations around the world invested heavily in its implementation. The core values of devops is effectively based on the Agile Manifesto but with one slight change which moves the focus from creating a working software to one that is more interested in the end-to-end software service mechanism and delivery.

Why should you opt for a DevOps career?

For very long times the development and the operations teams of any software enterprise have stayed at arm’s length. But this organizational cultural shift thanks to devops a lot of changes are happening in forward-thinking enterprises.

Ansible Vault: Ansible Lookup Plugin for Secrets Stored in Vault

ansible-vault lookup module 

This is a lookup module for secrets stored in HashiCorp Vault. Supports Ansible 1.9.x and 2.x

Deprecation notice

ansible-vault has been deprecated due to lack of personal usage of ansible and vault over the last years. There are other plugins such as hashivault which provide the same functionality and are better maintained.

Installation

lookup plugins can be loaded from several different locations similar to $PATH, see lookup_plugins. An example setup can be found in the tests directory.

The source for the plugin can be pointed to via a requirements.yml file, and accessed via ansible-galaxy.

Configuration

The address to the Vault server:

export VAULT_ADDR=http://192.168.33.10:8200/

The plugin supports both Vault auth token and GitHub auth token. To use Vault auth token:

export VAULT_TOKEN=56f48aef-8ad3-a0c4-447b-8e96990776ff

If your Vault server is configured to use GitHub auth token:

export VAULT_GITHUB_API_TOKEN=56f48aef-8ad3-a0c4-447b-8e96990776ff

The plugin also supports Vault's CA-related environment variables, to enable use of a server certificate issued by a not-widely-trusted Certificate Authority. Use of this feature in the plugin requires Python 2.7.9.

export VAULT_CACERT=/etc/ssl/certs/localCA.pem
export VAULT_CAPATH=/etc/ssl/localCA

The Vault address, CA certificate, and path can also be set via the Ansible variables vault_addr, vault_cacert, and vault_capath, respectively.

export VAULT_CAHOSTVERIFY="no"

This avoid the hostname check for Vault certificate (useful with self-signed certicates). This option can also be set via the Ansible variable vault_cahostverify.

export VAULT_SKIP_VERIFY=1

This will disable ssl certs validation. VAULT_CACERT, VAULT_CAPATH and VAULT_CAHOSTVERIFY have to be unset. Can also be set via Ansible variable vault_skip_verify: <bool>.

For more information on setting variables in Ansible, see the variables docs.

The Vault token intentionally can not be set via an Ansible variable, as this is generally checked into revision control and would be a bad security practice somewhat defeating the purpose of using Vault. The token can be read from the file $HOME/.vault-token, as documented at Vault environment variables.

If any such parameter is set by both an environment variable and an alternative means, the environment variable takes precedence.

Caching

By default secrets fetched from Vault will be cached in memory, unless you specify

export ANSIBLE_HASHICORP_VAULT_USE_CACHE=no

Note that secrets will be fetched once per fork (defaults to 5). If you turn off this feature by toggling above variable, all lookups will be done per node instead.

Approle support

If you want to use the Approle auth backend, you can do this by setting the follwing environment variables. If those vars are set, it is tried to get an approle token. If caching is enabled, the token is stored in the cache, so that it can be reused.

export ANSIBLE_HASHICORP_VAULT_ROLE_ID=ba78195c-12c9-557f-f8e2-75705b9b52ec
export ANSIBLE_HASHICORP_VAULT_SECRET_ID=5a4d079b-e6aa-ad54-8b0c-09dd35b740ee

Per default the authentication will be done against ${YOUR_HOST}/v1/auth/approle/login You can change this to fit your layout by setting the following var to your value:

export ANSIBLE_HASHICORP_VAULT_ROLE_PATH=v1/auth/my/role/path/approle/login

Usage

ansible-vault works as any other lookup plugin.

- debug: msg="{{ lookup('vault', 'secret/foo', 'value') }}"
# templates/example.j2

# Generic secrets
{{ lookup('vault', 'secret/hello').value }} # world
# Generic secrets with parameters
{{ lookup('vault', 'pki/issue/example-dot-com common_name=foo.example.com format=pem_bundle').certificate }}
# Specify field inside lookup
{{ lookup('vault', 'secret/hello', 'value') }} # world
# This syntax for Ansible 1.9.x
{{ lookup('vault', ['secret/hello', 'value']) }} # world

# Dynamic secrets
{% set aws = lookup('vault', 'aws/creds/deploy') %}
access_key = {{ aws.access_key }} # AKSCAIZSFSYHFGA
secret_key = {{ aws.secret_key }} # 4XSLxDUS+hyXgoIHEhCKExHDGAJDHFiUA/adi

If the desired value is stored within Vault with the key 'value' (like 'value=world' shown above), within a task, the lookup can be performed with:

with_vault:
- secret/hello

And then referenced with "{{ item.value }}"

Alternatively, the lookup can be performed with:

with_vault:
- secret/hello
- value

And then referenced with "{{ item }}"

Both of these forms work with both Ansible 1.9.x and 2.x. They only work within tasks, though. You can not use the with_vault: syntax within a variable definition file.

Troubleshooting

If you use the version of Ansible shipped with Ubuntu 16.04 (2.0.0.2-2ubuntu1) and get the error Error was sequence item 0: expected string, dict found then you should install Ansible from the PPA instead. Related to this Ansible PR

What's the difference between ansible-vault and hashi_vault

  • (Ansible Vault) No external dependencies; (hashi_vault) requires hvac
  • (Ansible Vault) Uses the same environment variables as vault itself
  • (Ansible Vault) Quicker update cycle
  • (Ansible Vault) Supports dynamic secrets
  • (Ansible Vault) Supports custom fields
