ModSecurity

Pre-configured with rules from OWASP CRS on my default. If you want to disable it for a particular location simply set it to off

server
{
  listen 80;
  listen [::]:80;
  listen [::]:443 ssl http2;
  listen 443 ssl http2;

  server_name insecure.example.com;

  set $upstream "http://10.0.0.1:9000";

  include /etc/nginx/defaults/https.conf;
  include /etc/nginx/defaults/resolver.conf;

  location /
  {
    include /etc/nginx/defaults/proxy.conf;
    proxy_pass $upstream;
    modsecurity off;
  }

  include /etc/nginx/defaults/error-page.conf;

  ssl_certificate /etc/letsencrypt/live/insecure.example.com/fullchain.pem; # managed by Certbot
  ssl_certificate_key /etc/letsencrypt/live/insecure.example.com/privkey.pem; # managed by Certbot

  ssl_trusted_certificate /etc/letsencrypt/live/insecure.example.com/chain.pem; # managed by Certbot
  ssl_stapling on; # managed by Certbot
  ssl_stapling_verify on; # managed by Certbot

}

Certbot

Easily add SSL security to your nginx hosts with certbot. docker exec -it nginx-modsecurity /bin/sh will bring up a prompt at which time you can certbot to your hearts content.

or

docker exec -it nginx-modsecurity certbot --no-redirect --must-staple -d example.com

It even auto-renew's for you every day!
