DevOps: Automate your infrastructure using Ansible and IaC

Learn to automate your infrastructure with Ansible by exploring playbooks, YAML basics, and validation, then install, configure, and verify Ansible.

Explore Ansible as an IT automation and configuration management tool, learn YAML foundations, and see how playbooks and roles automate provisioning and software deployment without agents.

Explore YAML basics, including lists, dictionaries, and complex data structures, and how Ansible playbooks rely on valid YAML. Use YAML lint to validate and catch formatting errors.

Set up a test environment for Ansible using three Ubuntu servers and a control host, review playbook and YAML formats, and note hardware requirements such as 256 megabytes of RAM.

Download all course resources from the provided URL, including the demos code and slides, and review them offline on your local machine for upcoming demos.

Set up an ansible environment in AWOS with an ansible host and two test nodes in a single VPC in Asia Pacific Singapore, then install and verify ansible.

Discover how ansible configuration files and a defined priority order control behavior—from ANSIBLE_CONFIG to /etc/ansible/ansible.cfg—covering inventory, ssh, facts, host key checking, and vault settings.

Explore how ansible inventory groups hosts and defines host variables to target playbooks. Learn default inventory locations such as /etc/ansible/hosts and how patterns map private ips to test nodes.

Verify your ansible setup by using ssh-agent with the private key and testing connectivity with the ping module across all hosts and inventory groups.

Learn to run commands and execute tasks on remote hosts with Ansible, explore options and variables, and dive into playbooks with sections like the target variable and task sections.

Learn to run Ansible commands with ad hoc approaches or playbooks, using modules from the module library and enabling parallel execution across multiple hosts.

Explore ansible ad-hoc commands for tasks like ping and copy, and review module documentation to understand the open-source module library and when ad-hoc commands fit playbooks.

Explains ansible facts and the setup module, showing how system details drive playbooks and enable OS, RAM, IP addresses, and network interfaces filtering.

Explore Ansible variables as temporary placeholders to avoid hard coding, learn naming rules (underscores, no hyphens), and see how to define and use variables in inventories, playbooks, and roles.

Explore building and running an Ansible playbook, defining hosts and variables, and installing packages with the apt module. Learn about become privileges, update cache, and reading module documentation.

Execute an ansible playbook to install engine X and gather remote facts, then add a file copy task and verify changes across nodes, highlighting infrastructure as code and versioned playbooks.

Dive into writing a standalone Ansible playbook, examining its structure with target variable, tasks, and handlers, and exploring loops and conditionals.

Explore Ansible playbooks from basics to complex configurations, including creating a new playbook to install Apache, using the service module, templates, debug statements, and loops.

Learn to install Apache web server on remote nodes using an Ansible playbook. Verify the inventory, ping hosts, and ensure idempotent deployment.

Automate apache webserver setup with an Ansible playbook, use the copy module to place index.html in /var/www/html, configure the web portal host group, and run with sudo privileges.

Validate that the Apache service is running on node 0 1 by curling the default document from localhost to obtain a valid response, after opening AWOS security groups for port 80.

Learn how to manage the Apache web server with Ansible by stopping and starting service using the service module, validate with curl, and apply handlers and notifications for idempotent changes.

Use the Ansible template module to create dynamic configuration files from Jinja templates, substituting variables like ansible_host, and trigger handlers via notify to manage Apache.

Automate infrastructure with Ansible templates, multiple handlers, and notifiers, using dry run check mode to verify changes while templating host-specific configurations.

Learn to debug Ansible playbooks by using register variables and the debug module to print task outputs, validate changes with check mode, and troubleshoot with uptime and copy status.

Explore Ansible loops and conditionals to automate repeated tasks in playbooks, using with_items and until to install multiple packages with the apt module and control task execution.

Master conditionals and until in an Ansible playbook for Apache install. Use when directives to target hosts, test conditions, and retry with delay until the service is active.

Practice using an ansible playbook to start the Apache service, observe until conditions, and verify active running status, while exploring loops, conditionals, and roles.

Combine playbooks, Galaxy, modules, loops, and conditionals to automate infrastructure with Ansible and deploy WordPress using Ansible rules and playbook.

Secure sensitive data with Ansible vault, decrypt with a master password, and use encrypted information in playbooks, while exploring modular playbooks with tags and roles and a Sipple galaxy.

Explore how to use ansible vault to encrypt and decrypt data. Create a vault, store sensitive information in a yaml file, and view decrypted contents with the master vault password.

Master common Ansible modules such as set up, file, yum, service, copy, user, and command, and learn to gather host facts, manage files and permissions, and use vault for security.

Explore common ansible modules, including apt, yum, app, service, copy, and user modules, with hands-on user creation examples and guidance on command versus shell modules and module docs.

Master Ansible command line usage for ad hoc commands and playbooks, using -m and -a with the shell module to tail logs, grep errors, and monitor multiple nodes for troubleshooting.

Explore how Ansible roles organize tasks, files, and handlers into structured groups for reuse across playbooks. See how roles enable sharing and improve maintainability.

Explore the ansible roles directory structure, including tasks, handlers, vars, and templates. Centralize common roles on a remote file server and organize WordPress, Apache, and common packages.

Deploy WordPress using an Ansible playbook that orchestrates multiple roles, including server and WordPress. Set up pre_tasks and post_tasks, and use an inventory with web_hosts and db_hosts to target hosts.

Automate WordPress deployment with an Ansible role by downloading and extracting WordPress, updating Apache site configuration, and configuring WordPress settings via database credentials defined in defaults and vars.

Automate WordPress deployment with Ansible roles and a main playbook, installing packages, configuring Apache and WordPress, and verifying the site on the web host.

Discover how Ansible roles boost automation by reusing community-driven Galaxy roles, search and install engine X roles, inspect role structures and templates, and publish your own roles.
