Caddy is a web-server, commonly used as a reverse proxy (meaning it sits in front of other services and routes traffic to them). It offers SSL certificates via Let's Encrypt.

Usage

This directory has the basic set of files needed to create a caddy server. Because caddy uses a plugin architecture, the Dockerfile builds the image that is used, which includes cloudflare's DNS provider for verifying the domain of the server in order for it to obtain SSL certificates.

Environment Variables

The .env file has the common environment variables needed in order to obtain SSL certificates, these values need to be updated.

Caddyfile

The configuration for the caddy server is found in the caddy/Caddyfile. There is a block included as an example of setting up a reverse proxy that will issue a wildcard certificate for the domains that are listed.

Network

The proxy network needs to be created prior to starting the container. You can use the following command to create the network:

docker network create --driver=bridge proxy

This allows you to place other containers running on the same host on this network and configure the reverse proxy using their container name.
