We run a server with Ubuntu 14.04 running in an LXContainer. We have a FPM-Suexec setup with configuration split up into individual config files for each user, all in /etc/apache2/sites-available . Until now, we used start.com certificates and did everything manually.
The keys are already there, also in this directory, as are the existing certs and intermediary files.
Now, the instructions just say that we have to download and run the installer script and then fire up certbot, but it does not explain, what certbot is actually going to do and what kind of config it can handle. I am a bit reluctant to just give it a try, as this is going to affect a number of users.
So can anyone point me to some technical documentation explaining what kind of setup certbot expects and what it will do?
Thank you very much in advance!
