What roles have you written in Ansible?

In Ansible, I wrote roles for automating deployment and server configuration, including:

• Installing and configuring web servers (e.g., Nginx, Apache).
• Setting up databases (PostgreSQL, MySQL).
• Deploying applications and managing dependencies.
• Configuring monitoring and logging systems.

Roles typically contain tasks, templates, variables, and handlers, which allow for code reuse and structuring. For example, a role for installing Nginx includes tasks for package installation, copying configuration files, and restarting the service.

Example of a role structure:

roles/
  nginx/
    tasks/main.yml
    templates/nginx.conf.j2
    handlers/main.yml
    vars/main.yml

In tasks/main.yml, the steps for installation and configuration are described.
