# Caddy

Opinionated

This guide is opinionated. If you use other conventions or folder layouts, feel free to change the commands and paths.

We're using Caddy here as reserve proxy to serve `wg-easy` on https://wg-easy.example.com via TLS.

## Create a docker composition for `caddy`

    .
    ├── compose.yml
    └── Caddyfile

    1 directory, 2 files

    # compose.yml

    services:
        caddy:
            container_name: caddy
            image: caddy:2.10.0-alpine
            # publish everything you deem necessary
            ports:
                - '80:80/tcp'
                - '443:443/tcp'
                - '443:443/udp'
            networks:
                - caddy
            restart: unless-stopped
            volumes:
                - './Caddyfile:/etc/caddy/Caddyfile:ro'
                - config:/config
                - data:/data

    networks:
        caddy:
            name: caddy

    volumes:
        config:
        data:

    # Caddyfile

    {
            # setup your email address
            email mail@example.com
    }

    wg-easy.example.com {
            # since the container will share the network with wg-easy
            # we can use the proper container name
            reverse_proxy wg-easy:80
            tls internal
    }

...and start it with:

    sudo docker compose up -d

## Adapt the docker composition of `wg-easy`

    services:
      wg-easy:
        # sync container name and port according to Caddyfile
        container_name: wg-easy
        environment:
          - PORT=80
        # no need to publish the HTTP server anymore
        ports:
          - "51820:51820/udp"
        # add to caddy network
        networks:
          caddy:
        ...

    networks:
      caddy:
        external: true
      ...

...and restart it with:

    sudo docker compose up -d

You can now access `wg-easy` at https://wg-easy.example.com and start the setup.
