Ansible Vault Password Validation Before Running a Playbook
Introduction
When working with Ansible, we often need to store sensitive information such as passwords, usernames, and other credentials. Keeping these values in plain text files is risky because anyone who can access those files can read the information.
Incase if you don’t have medium premium, read here:
Ansible Vault helps solve this problem by encrypting sensitive files with a password. Instead of storing readable content, the file contains encrypted data that can only be viewed or edited after entering the correct Vault password.
Ansible Vault encrypts sensitive data such as passwords and secret variables. However, running ansible-playbook with --ask-vault-pass does not guarantee that the password will be validated immediately. Ansible validates it when it needs to decrypt Vault-encrypted content.
In this blog, we will create an encrypted Vault file, verify the password, and configure a custom error message to display when an incorrect password is entered. We will also see how to validate the password before running an Ansible playbook.
