I never saw it as a problem for nginx to just serve web content and let certbot handle cert renewals. Whatever happened to doing one thing well and making it composable? Fat tools that try to do everything inevitably suck at some important part.

This optional module makes simple cases simpler.

Having distinct tools for serving content and handling certs is not a problem, and nothing changes on this side. Moreover, the module won't cover every need.

BTW, cerbot is rather a "fat tool" compared to other acme tools like lego. I've had bad experiences with certbot in the past because it tried to do too much automatically and it's hard to diagnose – though I think certbot has been rewritten since then, since it has no more dependency on python zope.

It's kind of annoying to set up. Last I remember certbot could try to automatically configure things for you but unless you had the most default setup it wouldn't work. Just having Nginx do everything for you seems like a better solution.

Certbot can just as easily work with a directory you have nginx set up to point .well-known/acme-challenge/ to. No automatic configuration magic needed.

I wonder about the same thing. I've come to the conclusion that it's driven a lot by Management-Ideal definition of devops: developers who end up doing OPs without sufficient knowledge or experience to do it well.

Nginx with certbot is annoying to setup. Especially with HTTP challenge. Mostly because of a circular dependency. You need nginx to clear the challenge and once verboten gets a cert you need to reload nginx.

I switched to Lego because it has out of the box support for my domain registrar so I could use DNS instead of HTTP challenge. It’s also a single go binary which is much simpler to install than certbot.

There is no circular dependency since the HTTP challenge uses unencrypted port 80 and not HTTPS. Reloading nginx config after cert updates is also not a problem as nginx can do that without any downtime.

There’s dependency in the nginx config. You have to specify where your certs are. So you have to have a working config before you start nginx, then you need to get certs and change config with the cert/key location before you can HUP nginx. This is extremely brittle, especially if you have a new box or a setup where you regularly bring up clean nodes as that’s when you can get all sorts of unexpected things to happen. It’s much less brittle when you already have a cert and a working config and just renew the certificate but not all setups are like that. I can’t even confidently say that most are like that.
