caddy-proxy

caddy-proxy automatically generates Caddy reverse proxy configurations for docker containers like jwilder/nginx-proxy for Nginx.

Usage

The template generation only works with docker-compose file version 2.

First, you'll need to create an external docker network named 'caddy-proxy'.

$ docker network create -d bridge caddy-proxy

Then Clone this repository.

$ git clone https://github.com/kirel/caddy-proxy
$ cd caddy-proxy

Set a proper email address for LETSENCRYPT_EMAIL in caddy/docker-compose.yml.

And start the caddy and caddy-gen containers.

$ cd caddy
$ docker-compose up -d

Then set the VIRTUAL_HOST variable to a fully qualified domain name in your app (see app1/docker-compose.yml or app2/docker-compose.yml for examples).

version: "2"

networks:
  proxy-tier:
    external:
      name: caddy-proxy

services:
  app1:
    container_name: app1
    image: httpd
    networks:
      - proxy-tier
    environment:
      VIRTUAL_HOST: "<YOUR FQDN>"
      VIRTUAL_NETWORK: "caddy-proxy"
      VIRTUAL_PORT: 80
    restart: always

Start your app:

$ cd ../yourapp
$ docker-compose up -d

Please note, that this caddy configuration uses the Letsencrypt staging environment. This means your browser will warn you about an insecure connection. For use in production remove the -ca=https://acme-staging.api.letsencrypt.org/directory flag in caddy/docker-compose.yaml.
