In this article, we will delve into the realm of encrypting secrets with Ansible Vault, exploring its features and demonstrating step-by-step how to secure your sensitive information.

Getting Started:

Ansible Vault operates seamlessly with Ansible playbooks, allowing users to encrypt entire files or specific variables within their scripts. To start encrypting secrets, follow these steps:

1. Install Ansible:

Ensure Ansible is installed on your system. If not, install it using your package manager or a virtual environment.

# For example, using pip
pip install ansible

2. Create a New Ansible Vault:

Create a new Ansible Vault file using the command:

ansible-vault create secrets.yml

This will prompt you to set a password for encrypting and decrypting the vault file. Choose a strong password and keep it secure.

Managing Secrets:

3. Edit the Vault File:

Edit the vault file to add your sensitive data. Use a text editor of your choice:

ansible-vault edit secrets.yml

This will open the file in an encrypted state. Add your variables in the YAML format.

database_password: your_secure_password
api_key: your_api_key

4. View Encrypted Content:

To view the encrypted content of the vault file:

ansible-vault view secrets.yml

This will display the encrypted data, ensuring that your secrets are well-protected.

Integrating with Playbooks:

5. Include Vaulted Variables in Playbook:

In your Ansible playbook, reference the vaulted variables:

- name: Playbook Example
hosts: servers
- secrets.yml
- name: Ensure database is configured
password: ""

This ensures that your sensitive information is seamlessly integrated into your automation workflow.

Working with Multiple Vault Files:

6. Create Multiple Vault Files:

For better organization, you can create multiple vault files for different purposes:

ansible-vault create database.yml
ansible-vault create api.yml

7. Reference Multiple Vault Files:

In your playbook, reference multiple vault files:

- name: Playbook Example
hosts: servers
- database.yml
- api.yml
# Your tasks here
