Ansible Vault Quick Start

• Ansible Vault encrypts variables and files so you can protect sensitive content such as passwords or keys rather than leaving it visible as plaintext in playbooks or roles.

• 5 steps or less to quick start with ansible vault

1. Create password stored file to hold the master key

passwd_file

~: cat passwd_file
pLECtontABre

2. Generate encrypted password and data conent

• Password for ssh-login

  $ ansible-vault encrypt_string --vault-id vagrant@passwd_file 'rootroot' --name vagrant
  vagrant: !vault |
          $ANSIBLE_VAULT;1.2;AES256;vagrant

• Update the encrypted things to var.yaml ``` vagrant: !vault |

      $ANSIBLE_VAULT;1.2;AES256;vagrant

### **3. Create ansible task to test decryption**
- [`test.yml`](https://github.com/vumdao/ansible-vault/blob/master/test.yml): Variable `my_data_encrypted` as encrypted value

⚡ $ cat test.yml

• hosts: all become: true vars_files:
  • var.yaml tasks:
  • name: ansible vault test debug: msg: "{{ my_data_encrypted }}" ```
• inventory: variable vagrant as the encrypted value ``` ⚡ $ cat inventory [ubuntu] 192.168.121.21

[all:vars] ansible_connection=ssh ansible_user=vagrant ansible_ssh_pass={{ vagrant }}

### **4. Run ansible-playbook**

⚡ $ ansible-playbook test.yml --vault-id dev@passwd_file -i inventory -e @var.yaml ok: [192.168.121.107]

---
