title: How to install Certbot (Let's Encrypt) without interaction?
body: <p>I am writing a bash script which bootstraps the whole project infrastructure in the freshly installed server and i want to configure ssl installation with letcecrypt certbot. After I execute line:</p>
  
  <pre><code>certbot --nginx -d $( get_server_name ) -d www.$( get_server_name ).com
  </code></pre>
  
  <p>I get prompted for few questions. Can certbot be run without any interactions while passing some of the params as arguments or something ?</p>
