Docker Web Manager

Tool to simplify the management of web container in Docker.

Setup

1. Create the web network by running the command ./bin/create-network.sh
2. Run docker-compose up -d

How it works

This is based on the jwilder/nginx-proxy Nginx proxy docker container, which will automatically proxy traffic when new containers come online. The container will watch the VIRTUAL_HOST environment variable on containers and proxy traffic from the domain specified in the variables value to the container. This also supports SSL with letsencrypt automagically. For SSL set the LETSENCRYPT_HOST and LETSENCRYPT_EMAIL environment variables.

VIRTUAL_HOST=example.com
LETSENCRYPT_HOST=example.com
LETSENCRYPT_EMAIL=web@example.com

Example website with docker-compose.yml

Here is an example docker-compose.yml that will get a site working quickly with the nginx proxy.

version: '2'

services:
  whoami:
    image: jwilder/whoami
    environment:
      - VIRTUAL_HOST=example.com
      - LETSENCRYPT_HOST=example.com
      - LETSENCRYPT_EMAIL=web@example.com

networks:
  default:
    external:
      name: web
  web:
    external: true

Troubleshooting

DNS does not resolve

Web browsers tend to aggressively cache DNS info. If you are getting a message that the domain cannot resolve, but the container is running, try flushing the DNS cache.

On Mac: sudo killall -HUP mDNSResponder
