Caddy

!!! note "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 reverse 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 [email protected]
}

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.
