Ansible 101
summary
Ansible claims to automate reaching a desired system state using agentless SSH and YAML playbooks applied against an inventory of hosts. The demo explains modules for packages, services, users and cloud providers, privilege escalation, batching and conditional loops, and the fact collector gather_facts. It runs against different distros without target agents, handles missing packages and notifications, and scales from small labs to thousands of hosts — illustrated by a 10,000-line app with about 250 package dependencies.
