Usage of Docker Compose (docker-compose) with NGINX proxy and Letsencrypt

Docker Compose (docker-compose) for docker-letsencrypt-nginx-proxy-companion

Purpose

This docker-compose file, version '3', was built to help using NGINX as web proxy to your containers, integrated with LetsEncrypt certification, using the great work of @jwilder with docker-gen and nginx-proxy along with the ultimate tool docker-letsencrypt-nginx-proxy-companion designed by JrCs to integrate the great SSL Certificates from the best LetsEncrypt.

Usage

In order to use, you must follow these steps:

Clone this repository:

git clone https://github.com/evertramos/docker-compose-letsencrypt-nginx-proxy-companion.git

Or just copy the content of docker-compose.yml, as of below:

version: '3'
services:
  nginx:
    image: nginx
    labels:
        com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy: "true"
    container_name: nginx
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ${NGINX_FILES_PATH}/conf.d:/etc/nginx/conf.d
      - ${NGINX_FILES_PATH}/vhost.d:/etc/nginx/vhost.d
      - ${NGINX_FILES_PATH}/html:/usr/share/nginx/html
      - ${NGINX_FILES_PATH}/certs:/etc/nginx/certs:ro

  nginx-gen:
    image: jwilder/docker-gen
    command: -notify-sighup nginx -watch -wait 5s:30s /etc/docker-gen/templates/nginx.tmpl /etc/nginx/conf.d/default.conf
    container_name: nginx-gen
    restart: unless-stopped
    volumes:
      - ${NGINX_FILES_PATH}/conf.d:/etc/nginx/conf.d
      - ${NGINX_FILES_PATH}/vhost.d:/etc/nginx/vhost.d
      - ${NGINX_FILES_PATH}/html:/usr/share/nginx/html
      - ${NGINX_FILES_PATH}/certs:/etc/nginx/certs:ro
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - ./nginx.tmpl:/etc/docker-gen/templates/nginx.tmpl:ro

  nginx-letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion
    container_name: nginx-letsencrypt
    restart: unless-stopped
    volumes:
      - ${NGINX_FILES_PATH}/conf.d:/etc/nginx/conf.d
      - ${NGINX_FILES_PATH}/vhost.d:/etc/nginx/vhost.d
      - ${NGINX_FILES_PATH}/html:/usr/share/nginx/html
      - ${NGINX_FILES_PATH}/certs:/etc/nginx/certs:rw
      - /var/run/docker.sock:/var/run/docker.sock:ro
    environment:
      NGINX_DOCKER_GEN_CONTAINER: "nginx-gen"
      NGINX_PROXY_CONTAINER: "nginx"

Create an .env file and say where you will locate the nginx files:

NGINX_FILES_PATH=/path/to/your/nginx/data

Change the file docker-compose.yml with you own settings:

3.1. Set your PROXY Network

Your wordpress container must be in the same network of your nginx proxy.

networks:
  default:
    external:
      name: your-network-name

3.2. Set your IP address (optional)

On the line ports add as follow:

    ports:
      - "YOUR_PUBLIC_IP:80:80"
      - "YOUR_PUBLIC_IP:443:443"

Get the latest version of nginx.tmpl file (only if you have not cloned this repostiry)

curl https://raw.githubusercontent.com/jwilder/nginx-proxy/master/nginx.tmpl > nginx.tmpl

Make sure you are in the same folder of docker-compose file, if not, you must update the the settings - ./nginx.tmpl:/etc/docker-gen/templates/nginx.tmpl:ro.

Start your project

docker-compose up -d

Please note that when running a new container to generate certificates with LetsEncrypt it may take a few minutes, depending on multiples circunstances.

Your proxy is ready to go!

Next Step

If you want to test how it works please check this working sample (docker-compose.yml)

wordpress-docker-letsencrypt

Or you can run your own containers with the option -e VIRTUAL_HOST=foo.bar.com alongside with LETSENCRYPT_HOST=foo.bar.com, exposing port 80 and 443, and your certificate will be generated and always valid.
