Config Management for Programmers: How to Set Up Virtual Machines the Easy Way
summary
Describes using configuration-management tools Ansible, Puppet and Chef to speed up creating virtual machines and Docker containers by separating provisioning (images/machines) from configuration (packages, users, files, services). Compares agent-based vs agentless setups—agents for many-production nodes with continuous enforcement, agentless for one-off or small infrastructures—and advocates declarative languages to avoid configuration drift; includes demos of common tasks like installing packages, copying configs and asserting service state to produce reproducible, testable environments.
