Custom Caddy Image

A containerized build of Caddy with pre-installed plugins.

Included Plugins

• nginx-adapter: Converts Nginx config to Caddy
• caddy-teapot-module: Returns HTTP 418 I'm a teapot responses
• Cloudflare DNS: Supports Cloudflare DNS provider for ACME challenges

Supported Architectures

• linux/amd64 (x86-64)
• linux/arm64 (ARM v8)

Usage

Pull from GitHub Container Registry:

docker pull ghcr.io/rdiazlugo/caddy

Or from Docker Hub:

docker pull reinaldo122/caddy

Build Locally

docker build -t my-caddy .

How It Works

The Dockerfile uses a multi-stage build:

1. Builder stage: Compiles Caddy with plugins using xcaddy
2. Runtime stage: Uses the official Caddy image with the custom binary

This approach keeps the final image minimal while including all necessary functionality.
