Ansible

ELI5 — The Vibe Check

Ansible is a tool that lets you automate the setup of servers by writing scripts called playbooks. Instead of SSH-ing into 50 servers and manually running commands, you write what you want done and Ansible does it on all of them at once. It's like writing a checklist that robots follow.

Real Talk

Ansible is an agentless IT automation tool that uses YAML-based playbooks to configure systems, deploy applications, and orchestrate infrastructure tasks over SSH. Unlike Terraform (which provisions infrastructure), Ansible focuses on configuration management of existing servers.

  tasks:
    - name: Install nginx
      apt:
        name: nginx
        state: present
    - name: Start nginx
      service:
        name: nginx
        state: started
