Explain the architecture and main components of the Ansible project.

Ansible is a tool for automation of configuration management and application deployment.

The main components of Ansible architecture:

• Control Node — the machine from which Ansible commands and playbooks are run.
• Managed Nodes (hosts) — target servers managed by Ansible.
• Inventory — a list of managed hosts, which can be in the form of a file or a dynamic script.
• Modules — individual scripts that perform specific tasks on managed hosts (e.g., installing packages, copying files).
• Playbooks — YAML files describing a sequence of tasks to be executed on hosts.
• Plugins — extensions for various functions, such as callback, connection, lookup.

Ansible operates based on SSH connections, without the need to install agents on managed hosts.

Example of a playbook:

- hosts: webservers
  tasks:
    - name: Install nginx
      apt:
        name: nginx
        state: present
