Introduction to Ansible Vault

In the vast landscape of automation, security is paramount. Ansible Vault is your shield, protecting sensitive information and ensuring that your secrets remain safe and sound. In this blog post, we'll unravel the significance of Ansible Vault, understanding its role in secure data storage, and mastering the art of encrypting confidential information.

Understanding Ansible Vault

What is Ansible Vault?

Ansible Vault is a feature that allows you to encrypt sensitive data, such as passwords or API keys, in your Ansible projects. It provides a secure way to store and manage confidential information, ensuring that only authorized users can access and decrypt the encrypted data.

Why Use Ansible Vault?

  • Secure Storage: Protect sensitive information from unauthorized access.

  • Version Control Compatibility: Vault integrates seamlessly with version control systems like Git.

  • Granular Access Control: Grant access to specific users or teams for managing encrypted files.

Encrypting Sensitive Information

Creating an Encrypted File

To create an encrypted file using Ansible Vault, use the following command:

ansible-vault create secrets.yml

This command will open an editor for you to input your secrets. Once you save and exit, the file will be encrypted.

Editing an Encrypted File

To edit an existing encrypted file, use:

ansible-vault edit secrets.yml

Encrypting a String

Encrypting individual strings is useful for tasks like password prompts. Use the ansible-vault encrypt_string command:

ansible-vault encrypt_string 'your_secret_string' --name 'variable_name'

This command outputs the encrypted string in a format suitable for inclusion in your playbook.

Using Encrypted Files in Playbooks

Referencing Encrypted Variables

In your playbook, you can reference encrypted variables by including the !vault tag:

- name: Playbook with Encrypted Variables
  hosts: web_servers
  become: yes
    - name: Ensure Nginx is configured with a secret
        src: nginx.conf.j2
        dest: /etc/nginx/nginx.conf
        secret_api_key: !vault |

Running Playbooks with Encrypted Variables

When running a playbook with encrypted variables, use the --ask-vault-pass option to provide the vault password:

ansible-playbook my_playbook.yml --ask-vault-pass -u your_username

Replace your_username with your actual username.


Ansible Vault stands as a formidable guardian, ensuring that your automation secrets remain confidential and secure. As you embrace Ansible Vault in your projects, you fortify the foundations of your automation endeavors.
