Advanced Ansible Interview Questions and Answers

1. How do you manage role dependencies in Ansible?

• Answer: Role dependencies are managed in the meta/main.yml file of an Ansible role. You can list other roles required by a role under the dependencies section. Ansible resolves these dependencies automatically when the role is executed.

2. Explain how you can dynamically generate inventory in Ansible for a cloud environment.

• Answer: Ansible integrates with cloud services' APIs through inventory scripts or plugins, like aws_ec2 for AWS or gcp_compute for Google Cloud, to dynamically generate inventory based on the current state of cloud resources.

3. Describe the strategy you would use to encrypt sensitive data in Ansible.

• Answer: Use Ansible Vault to encrypt sensitive data. It can encrypt entire files, variable files, or specific strings within a playbook. With Ansible Vault, you can also decrypt files, edit encrypted files, and even rekey files if necessary.

4. What are the implications of using ignore_errors in Ansible playbooks, and how do you handle errors more gracefully?

• Answer: Using ignore_errors may hide underlying problems and lead to unexpected playbook behavior. To handle errors gracefully, use error handling with failed_when, rescue, and always blocks within block statements to manage failures explicitly.

5. How do you achieve idempotency in Ansible tasks and ensure a playbook can be safely run multiple times?

• Answer: Ensure tasks check the current state before making changes. Use modules designed for idempotency, such as file for file management and template for templating, which only make changes if the desired state is not met.
