nginx-auto-ssl

Docker nginx proxy for swarm with auto LE ssl processing.

Run:

Clone repo.
Create nginx configuration file for ssl virtual hosts, like this (note the path to the certificate):

server {
    listen       443 ssl;
    server_name  domain.example.com;

    auth_basic "Restricted";
    auth_basic_user_file /etc/nginx/conf.d/htpasswd;

    ssl_protocols           SSLv3 TLSv1 TLSv1.1 TLSv1.2;
    ssl_certificate         /etc/nginx/ssl/domain.example.com/fullchain.pem;
    ssl_certificate_key     /etc/nginx/ssl/domain.example.com/private.key;

    location / {
        proxy_pass        http://my-web-service:8080;
        proxy_redirect    off;
        proxy_set_header  X-Forwarded-For       $remote_addr;
        proxy_set_header  Host      $host;
    }
}

Create stack.yml:

version: '3'
services:
  nginx:
    image: nginx-le-ssl
    volumes:
      - ./nginx/conf.d:/etc/nginx/conf.d/configs
      - ./nginx/ssl:/etc/nginx/ssl
    environment:
        DOMAINS_LIST: "domain.example.com"
    ports:
      - "80:80"
      - "443:443"

  my-web-service:
     image: my-web-swervice-image

my-web-service should listen on same port as set in nginx vh proxy_pass

proxy_pass        http://my-web-service:8080;

(do not publish port to outside).

Mount nginx config(s) to path /etc/nginx/conf.d/configs inside container. Its nessesery to mount the directory /etc/nginx/ssl as persistent volume.

docker stack deploy -c stack.yml mystack
