Https with let's encrypt behind a vpn?

Hi @Stephen

We are using LDAP authentication for the discourse. If credentials are stolen then someone could access everything else relating to the student at the University.

Would you know if I follow these instructions: Generating a Certificate Signing Request (CSR) in Ubuntu 16.04 | Liquid Web that is will work with discourse? I’ve setup https before, but never with a docker app, so I’m not sure if I need to do something different.
