The differences between certbot-auto and letsencrypt-auto are kind of driving me nuts. I wish they were documented (if they are I am unable to find it)
I maintain a docker container with nginx/letsencrypt based on ubuntu 14.04: https://hub.docker.com/r/aptalca/nginx-letsencrypt/
With letsencrypt-auto, I could easily install it during container build with the --help option. With certbot-auto, this option no longer installs or updates it. Running it without an option (or with just the --non-interactive option) produces an error, that breaks the container build.
Is there a way to just install with the auto script without running anything?
EDIT: Another reason for wanting to uncouple the script/dependency updates from cert renewals is that in my container, I have to stop the webserver during renewals (have to use port 443, so I have to use standalone as the webroot only works through port 80). I would like to minimize the down time. If updating occurs at the same time as the cert renewal, the downtime can be much longer.
