ansible-playbooks

Ansible playbooks automate configuration management by defining tasks in YAML files executed across your inventory of hosts. Write playbooks with task modules, run them with ansible-playbook, and Ansible handles idempotent application across web servers, databases, and other environments without requiring agents.

Organize playbooks using roles to group related tasks, handlers, and templates. Define separate inventory files per environment, use group variables for environment-specific settings, and structure roles hierarchically so playbooks remain modular, reusable, and maintainable across diverse infrastructure.

Define hosts and groups in inventory files, then reference those groups in playbooks to target specific servers. Ansible executes tasks against matched groups, letting you configure web servers, databases, or custom groups independently. Variables can be set per-host or per-group for fine-grained control.

Yes. Ansible playbooks are idempotent—running them multiple times produces the same result. Use handlers to restart services only when needed, version-control your playbooks, and leverage roles for reproducible deployments across staging and production environments.

Inline tasks work for simple playbooks, but roles encapsulate related tasks, handlers, templates, and variables into reusable units. Roles scale better for complex infrastructure, enable sharing across playbooks, and enforce consistent structure for maintainability and orchestration.

No. Ansible is agentless and requires only SSH access and Python on target hosts. This reduces deployment complexity and security surface compared to agent-based tools, making Ansible lightweight for orchestration across heterogeneous infrastructure.
