I totally disagree with this reply, and agree with the thread starter... I really, really do not see the point of this.

One command? Did you read the github page?

At the end, this doc even has you hand editing your nginx for SSL?!? Why on earth... why not just use certbot automation? This seems totally counter to the idea. Again, am I being dense? Is this just "look what I can do with docker that makes my life more complicated"? Honestly, at this point it feels like more work for less output.

This seems way harder than installing nginx and certbot, and now I have a hard dependency on docker and whatever else you pulled in.
