How to install ssl certificate on clean ubuntu 18 with minimal effort?

Question

ubuntu

By minimal effort, I mean not installing too much. On Ubuntu 18 server and docker. Tell me the optimal configuration, manuals - links.
Upd: There are certificate files. I just don't understand the setup. There was an experience of installing in nginx, but in the system, there is only a docker, and there is too little reluctance to hang it.

Answer 1

this question is better to be deleted, I didn’t formulate it exactly here, more precisely How to install an ssl certificate on Ubuntu + docker?

Answer 2

cp certfile.crt /etc/ssl/certs
cp certfile.key /etc/ssl/private
cd /etc/ssl/certs
ln -s certfile.crt `openssl x509 -hash -noout -in certfile.crt`.0

Answer 3

Wow, docker was mastered, but letsencrypt did not succumb.
