This is a docker nginx config based on https://github.com/matthiasnoback/nginx-multi-host-docker which itself seems to be based on https://github.com/jwilder/nginx-proxy
Our copy has various modifications:
- nginx-data service is simplified to allow for more streamlined updates to the template (nginx.tmpl) by bind mounting ./nginx-data
- nginx-static and nginx-certs volumes to hold static files and certs respectively
- nginx-vhost dir in this repo contains per virtual host configs
- nginx.tmpl handles new "protocol" "http+static", and adds advanced logging
- nginx service logs directly to graylog (see infra/docker-graylog)

If you change nginx-data/nginx.tmpl then push, you need to trigger a rebuild of the config files (which will also reload nginx as a side effect):

$ docker-compose restart nginx-gen

If you update the configs in nginx-vhost then push, you need to ask nginx to reload the config:

$ docker-compose exec nginx "nginx -r && nginx -s reload"

If you need to force renewal of the letsencrypt certificates:

docker-compose exec nginx-letsencrypt /app/force_renew

Original README

Setup for running multiple websites on a single server

Uses nginx as a proxy server, and the docker-gen and docker-letsencrypt-nginx-proxy-companion container utilities.
Serves secure websites with automatically generated and renewed Let's Encrypt certificates.
Only exposes one web server, connects to other web servers using a custom network.

Usage

If you didn't do so already, set up a server using docker-machine create.
Export the name you used for the server as the environment variable DOCKER_MACHINE_NAME, e.g.:

export DOCKER_MACHINE_NAME=personal-websites
Run ./deploy.sh to install the Nginx proxy server.

Now for every website you want to expose on the same server:

Write a Dockerfile for the website server, for example (assuming that copying some files to the default document root is sufficient):
```
FROM nginx:1.11-alpine
RUN rm -rf /usr/share/nginx/html
COPY web /usr/share/nginx/html
```

Define a service for that container in docker-compose.yml:

version: '2'

services:
    website:
        image: your-username/your-website-name
        build:
            context: .
            dockerfile: Dockerfile
        restart: always
        environment:
            - VIRTUAL_HOST=your.hostname.com
            - VIRTUAL_NETWORK=nginx-proxy
            - LETSENCRYPT_HOST=your.hostname.com
            - LETSENCRYPT_EMAIL=your@email.com
        networks:
            - proxy-tier

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

Deploy the website by running the following commands (of course it would make sense to automate this):

eval $(docker-machine env $DOCKER_MACHINE_NAME)
docker network create --driver bridge nginx-proxy || true
docker-compose pull
docker-compose up -d --force-recreate --no-build
docker-compose ps
eval $(docker-machine env -u)

It may take a minute or so before the secure site can be reached (because the certificate has to be created first).
