Stop Writing Repetitive Playbooks: Ansible Tags, Variables, Loops, Handlers and Conditions Decoded
Once you have written your first few Ansible playbooks, installed some packages, and started a couple of services, a natural question comes up: what else can Ansible do? The answer is quite a lot. This article walks through six features that turn a basic Ansible setup into something genuinely powerful: the Setup module, Tags, Variables, Loops, Handlers, and Conditional tasks. Each one builds on what you already know, and together they give you the tools to manage complex, real-world server environments cleanly and efficiently. Before going further, the environment being used here has one Ansible master and multiple worker nodes. Two are grouped as prod and two as dev inside /etc/ansible/hosts. SSH key-based authentication is already configured between the master and all worker nodes. If any of that is not set up yet, revisit passwordless SSH setup and inventory configuration before continuing.
