Ansible for the Absolute Beginner - Hands-On - DevOps

Learn yaml files as a data serialization language used for writing configuration and ansible playbooks, plus rules like three dashes, spaces for indentation, and maps or lists.

Explore ad hoc commands in Ansible to perform quick one-line tasks on managed nodes, using -m modules and -a arguments, with state checks to avoid unnecessary changes.

Demonstrates a simple Ansible playbook using debug and copy modules to print messages and copy a sample text file to remote servers, then validates changes with ad hoc commands.

Explore ansible modules and task plugins, learn how modules accept arguments and return information to Ansible, and see an example restarting the Apache web server with cli and yaml.

Identify the smallest unit of action in an Ansible playbook: a task, executed in order to achieve a goal such as setting up a web server or deploying an application.

Explore how Ansible playbooks deliver repeatable, reusable configuration and multi-machine deployments using YAML-based plays, each with hosts, variables, and tasks to automate complex setups.

Learn to create a yaml playbook that installs apache and starts the server on localhost, describe the playbook, and use the service module with become.

Explore Ansible inventory and host files, covering ini and yaml formats, default locations, and group-based host management, with ad hoc ping commands.

Understand host groups in Ansible, including all and specific hosts, and how to target multiple groups with a colon, exclude nodes, and intersect groups like web servers and staging.

Explore how Ansible uses variables to parameterize playbooks, including simple and list variables, registered facts, and runtime overrides via external files and extra-vars.

Roles split a playbook into multiple files, simplifying complex playbooks and enabling reuse. Rules group variables, tasks, files, templates, and modules into independent or interdependent collections.

Explore the Ansible role directory structure, including default, files, handlers, meta, tasks, templates, tests, and galaxy role, and learn how to name, namespace, and run an apt update playbook.

Discover the eight standard directories of an Ansible role and include at least one. Use include role to reuse roles and the Ansible Galaxy client to create role directory structures.

Master Ansible templates by using jinja variables in files with curly braces, and apply them with the template module to render src to dest on remote hosts under cluster conditions.

Master Ansible templates by creating a template with variables (my IP, my host, and my username) and running a localhost playbook to verify the destination file shows substituted values.

Learn how Ansible handlers run only after a task notifies a change, execute once after all tasks, and start, reload, restart, or stop services.

Learn how to use Ansible handlers within a demo playbook to update packages and copy inline content, with notify directives triggering update and data handlers and verifying file creation.
