Where is the official ACME v.2 client?

Hello, boulder engineer. I was trying to use the Certbot. But it is said that there is no package for nginx after the command sudo yum install certbot-nginx. After that I tried another method from here: https://certbot.eff.org/lets-encrypt/centos6-nginx but it is also said that “Certbot’s DNS plugins which can be used to automate obtaining a wildcard certificate from Let’s Encrypt’s ACMEv2 server are not available for your OS yet.”

I am not expert in all this staff and the idea of using the Docker seams to be very complicated for me.

Do you have any idea of simplifying the process? I created the request in the help topic here: Error whyle trying to install Cerbot for the Nginx
