you can checkout this gem

https://github.com/lardawge/carrierwave_backgrounder

this is a little bit outdated, and I hope Chris doesnt mind me posting this, this is what you would do on an ubuntu 18.04 and nginx:

sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository universe
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update

then

sudo apt-get install certbot python-certbot-nginx

now create the certificate

sudo certbot --nginx

this will alter your nginx site-enabled/default file, so make a copy and move it outside site-enabled/default to somewhere else safe.

here is a copy of my default file, I modified it a bit to work with action cable

upstream app {
        server 127.0.0.1:3000;
}
server {
    root /var/www/app_name_here/public;
    index index.html index.htm index.nginx-debian.html;
    server_name app_name_here; # managed by Certbot
    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://app;
    #   try_files $uri $uri/ =404;
    }
location /cable {
         proxy_pass http://app;
         proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
             proxy_set_header Connection "Upgrade";
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_set_header Host $http_host;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-Proto https;
             proxy_redirect off;
    }    

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/app_name_here/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/app_name_here/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /root/dhparams.pem; # managed by Certbot
}
server {
    listen 80 ;
    listen [::]:80 ;
    return 301 https://$host$request_uri;
}

do not copy and paste the default file, its here for you to look at :)
