Deprecated: use official image instead

A docker image for Caddy.

License

This image uses a release from github, so it is a subject to the project's Apache 2.0 license and not to the EULA license.

You can use it for almost everything. This project is licensed under MIT. See LICENSE.md for details.

Running

docker run -p 2015:2015 wemakeservices/caddy-docker

docker-compose example

This image is created to be used in docker-compose.yml. Here's an example:

version: '3'
services:
  caddy:
    image: "wemakeservices/caddy-docker:latest"
    volumes:
      - ./some/path:/root/.caddy  # to save certificates on disk
      - ./some/Caddyfile:/etc/Caddyfile  # to mount custom Caddyfile
    ports:
      - "2015:2015"
      - "80:80"
      - "443:443"
    depends_on:
      - web

  web:
    build: .
    command: python manage.py runserver 0.0.0.0:5000
    ports:
      - "5000:5000"

Changing default Caddyfile

Just specify another Caddyfile via command line:

docker run -p 2015:2015 -v `pwd`/test/Caddyfile:/etc/Caddyfile wemakeservices/caddy-docker

Backing-up certificates

Let's Encrypt has rate limits. It is wise to reuse certificates and back them up:

docker run -p 2015:2015 -v `pwd`/backup:/root/.caddy wemakeservices/caddy-docker

It is also possible to combine this trick with Changing default Caddyfile.

Changing Caddy's version

This image supports VERSION build-time argument:

docker build --build-arg VERSION=0.10.0 -t caddy:0.10.0 .

docker build -t caddy:latest .

And then run it locally:

docker run -p 2015:2015 caddy:latest
