Practice interview questions on this topic →Ansible Fundamentals

intermediateProHow playbooks organize plays and tasks, the modules you'll reach for most, and how idempotency shows up in a real playbook's output.
Variables and Templates
intermediateProHow Ansible variables are scoped and layered, how Jinja2 templating drives per-environment configuration files, and a worked example templating an nginx config across environments.
Roles and Reusability
intermediateProHow to break large playbooks into reusable roles, the standard role directory layout Ansible expects, and when to pull a role from Ansible Galaxy versus writing your own.
Ansible in Production
intermediateProHandlers for change-triggered restarts, tags for selective execution, Vault for secrets, and how Ansible fits alongside Terraform in a real infrastructure pipeline.
