  • 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 |

### **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]

< TASK [ansible vault test] >

    \   ^__^
     \  (oo)\_______
        (__)\       )\/\
            ||----w |
            ||     ||

ok: [192.168.121.107] => { "msg": "my_credential_data" }

< PLAY RECAP >
