In this article I am going to show you how to run a simple webserver using Caddy and Docker.

Caddyfile #

Let's write a Caddyfile that returns a simple "Hello World".

:80 {
	respond "Hello World"
}
Caddyfile

Now using docker, run the caddy:latest container while mounting the above Caddyfile as a volume.

docker run --rm --name caddy -p 8080:80 -v ${PWD}/Caddyfile:/etc/caddy/Caddyfile caddy:latest

Docker Compose #

When developing locally you would want to run Caddy using Docker Compose. Using the above Caddyfile, let's write a docker-compose.yaml file.

version: '3.8'

services:
  caddy:
    image: caddy:latest
    ports:
      - 8080:80
    volumes:
      - ${PWD}/Caddyfile:/etc/caddy/Caddyfile
docker-compose.yaml

Now run using docker compose.

docker compose up -d

Once the container is running test it out using curl.

curl localhost:8080
Hello World
