=== Open: ===

<syntaxhighlight>nano ~/projects/caddy/docker-compose.yml

</syntaxhighlight>

Replace the caddy service with:

<syntaxhighlight lang="yaml">services:
  caddy:
    image: caddy:latest
    container_name: wsi-caddy
    restart: unless-stopped
    expose:
* "80"
    volumes:
* ./Caddyfile:/etc/caddy/Caddyfile
* ./site:/usr/share/caddy
* caddy_data:/data
* caddy_config:/config
    networks:
* npm-net

</syntaxhighlight>

Important changes:
* ❌ removed ports: 80:80, 443:443
* ✔ added expose: 80 → makes Caddy reachable INSIDE Docker
* ✔ allows NPM to connect to Caddy on port 80 INSIDE THE NETWORK

=== <syntaxhighlight>Host: wsi-caddy ===
Port: 80

</syntaxhighlight>

Or sometimes:

<syntaxhighlight>IP: 172.22.0.x   (Caddy’s internal docker IP)
Port: 80

</syntaxhighlight>

But hostname-based upstream (<code>wsi-caddy:80</code>) is best.

=== <syntaxhighlight>cd ~/projects/caddy ===
docker compose up -d --remove-orphans

</syntaxhighlight>

Check status:

<syntaxhighlight>docker ps | grep caddy

</syntaxhighlight>

Now Caddy should start without errors.
