Ansible replaces repeated shell work with readable declarations of the state you want on managed hosts. This hands-on course builds that workflow from SSH access and inventory through playbooks, Jinja2 templates, and reusable roles.
You will manage localhost as the target so you can focus on Ansible’s structure rather than external infrastructure. Guided labs install and start Nginx, render a host-aware page, and package an installation task as a role; the final challenge combines Apache, a template, and a MariaDB role on the same host.
What You Will Learn
- Install Ansible and verify the control-node tooling
- Configure key-based SSH access to a managed host
- Create an INI inventory, group a host, and test it with Ansible’s ping module
- Write and run YAML playbooks with privilege escalation, package, and service tasks
- Define custom variables and use Ansible-provided inventory variables
- Render a Jinja2 template to a protected destination with a specified file mode
- Initialize, populate, syntax-check, and invoke an Ansible role
- Combine web-server tasks, a homepage template, and a database role in one play
Who This Course Is For
This intermediate course is for Linux users, junior system administrators, and DevOps learners who want to move from manual server commands to structured Ansible automation.
Prerequisites: Comfort with the Linux shell, SSH concepts, sudo, package and service management, basic YAML indentation, and simple HTML. Prior Ansible experience is not required.
Learning environment: A Debian-based Linux terminal with Ansible and administrator access. The control node and managed host are the same localhost, reached through SSH or a local connection depending on the lab.
Frequently Asked Questions
Will I automate multiple remote servers in this course?
No. You learn inventory groups and Ansible’s managed-host model, but all exercises target one lab machine named localhost. Multi-host topology, cloud inventory, and fleet orchestration are not covered.
What does the final “full-stack” challenge deploy?
It installs and starts Apache, deploys a Jinja2-rendered homepage, and uses a role to install and start MariaDB on the same host. It does not deploy application code, initialize a database schema, or connect an application to the database.
Does the course cover production Ansible architecture?
It introduces the core building blocks and a standard role layout. Advanced topics such as Vault, handlers, collections, dynamic inventory, testing, CI, and large-scale variable precedence remain outside the scope.
