How can secret data and confidential information be managed when using Ansible?

Ansible Vault is a built-in tool used for managing secret data in Ansible. It allows encrypting files containing confidential information (such as passwords, API keys, certificates) to store them securely in a repository.

Example of using Ansible Vault:

# Creating an encrypted file
ansible-vault create secrets.yml

# Editing an encrypted file
ansible-vault edit secrets.yml

# Running a playbook with encrypted data
ansible-playbook playbook.yml --ask-vault-pass

In addition to Vault, it is recommended to:

• Store secrets outside of code, for example in secret management systems (HashiCorp Vault, AWS Secrets Manager).
• Use environment variables or dynamic inventories to pass secrets.
• Minimize access to secrets and rotate keys.

Thus, Ansible Vault is the main and simple way to securely manage secrets in Ansible projects.
