Nginx reverse Proxy Lets Encrypt

Docker configuration to use letsencrypt automatically with jwilder nginx reverse proxy

TL;DR

A configuration to generate and renew your certificates automatically with ets Encrypt and Jwilder nginx reverse proxy.

You need docker 1.12+ and docker-compose 1.8+ (v2)

• Reverse proxy container name => michel
• Reverse proxy network name => nginx-proxy
• Starting the stack => make install

The reverse proxy is connected to the default bridge network thanks to the Makefile.

docker network connect bridge michel || true

Start

git clone git@github.com:ypereirareis/nginx-proxy-letsencrypt.git
cd nginx-proxy-letsencrypt
make install

Docker compose configuration

version: '2'
services:
  michel-nginx:
    image: jwilder/nginx-proxy
    container_name: michel
    restart: always
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "/var/run/docker.sock:/tmp/docker.sock:ro"
      - "/etc/nginx/conf.d"
      - "/etc/nginx/vhost.d"
      - "/usr/share/nginx/html"
      - "./conf/proxy.conf:/etc/nginx/conf.d/my_proxy.conf:ro"
#      - "PATH_TO_PASSWORDS:/etc/nginx/htpasswd"
#      - "PATH_TO_CERTS/certs:/etc/nginx/certs:ro"
#      - "PATH_TO_CUSTOM_CONFIG:/etc/nginx/conf.d/custom.conf:ro"
    networks:
      - nginx-proxy

  michel-letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion
    restart: always
    container_name: michel-letsencrypt
    volumes_from:
      - michel-nginx
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - "PATH_TO_CERTS/certs:/etc/nginx/certs:rw"
    networks:
      - nginx-proxy
#    environment:
#     - ACME_CA_URI=https://acme-staging.api.letsencrypt.org/directory

networks:
  nginx-proxy:
    external:
      name: nginx-proxy

How it works

Configuration based on those repositories:

• https://github.com/JrCs/docker-letsencrypt-nginx-proxy-companion
• https://github.com/fatk/docker-letsencrypt-nginx-proxy-companion-examples

I advise you to read the documentation of those repositories... and this section in particular.

Volumes

/etc/nginx/conf.d

Nginx configuration files are generated into this repository by the reverse proxy.

/etc/nginx/vhost.d

The "letsencrypts" docker container generates temporary virtual hosts to allow https://letsencrypt.org/ to verify the domain name.

/usr/share/nginx/html

The "letsencrypts" docker container generates a file into this volume. The file is accessed by https://letsencrypt.org/ during the domain validation process.

PATH_TO_CERTS/certs:/etc/nginx/certs:ro

The path where Letsencrypt certificates are going to be generated. The certs generation can be long.... please wait before killing everything !

PATH_TO_PASSWORDS:/etc/nginx/htpasswd
PATH_TO_CUSTOM_CONFIG:/etc/nginx/conf.d/custom.conf:ro

Those two volumes are here to add custom configuration, see https://github.com/jwilder/nginx-proxy
