Ansible Flashcards

Ansible is an open-source automation tool for configuration management, app deployment, and orchestration.

A playbook is a YAML file that defines tasks to be executed on hosts in a structured format.

Modules are discrete units of code in Ansible used to perform specific tasks like installing packages or managing files.

Roles are a way to group tasks, variables, handlers, and templates into reusable components.

An inventory is a file listing the hosts and groups of hosts that Ansible manages.

Ansible Vault allows you to encrypt sensitive information such as passwords or keys in your playbooks.

Idempotency means running a task multiple times will not change the system beyond the initial application.

You can use the `–check` flag for dry runs to simulate playbook execution without making actual changes.

Handlers are special tasks that run only when notified by other tasks (e.g., restarting a service).

Ansible uses SSH for communication with remote Linux/Unix systems and WinRM for Windows systems.

Variables are used to customize tasks and are defined in playbooks, inventories, or external files.

Collections are a distribution format for Ansible content like roles, playbooks, and plugins, enabling sharing and reuse.
