Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

In that case, running Certbot in this way won't work. Certbot can't see or configure nginx from outside of the container.
There aren't really any one-size-fits all instructions for Docker + Let's Encrypt. Every Docker environment is slightly different.
I would suggest looking up some articles on how other people have configured Let's Encrypt certificates inside Docker containers. If you're following some instructions/setup guide already for this Docker-based application, it's possible that the authors have already written instructions to setup SSL.
