## Architecture

**Network model:** A single Cloudflare Tunnel
(`cloudflared/`) creates and owns the `cloudflare-exposed`
external bridge network. Services that need internet
exposure declare and connect to this network. Services
that don't need Cloudflare exposure should **not** declare
any network in their compose file — Dokploy attaches its
own `dokploy-network` automatically on deploy (e.g. `n8n`,
`plex`, `traccar`, `watchtower`).
**Network model:** Services don't declare networks for
exposure. Dokploy attaches its own `dokploy-network` on
deploy to every service that has a domain, and Traefik routes
from there. The
Cloudflare Tunnel (`cloudflared/`) sends every public
hostname to `http://dokploy-traefik`. What is exposed is
decided by the tunnel's hostnames, the Dokploy domains and
Cloudflare Access, not by Docker networks.

**Container management:** Watchtower handles automatic
image updates using label-based opt-in

internal Docker services to the internet without opening
ports on the host.

This service creates the shared `cloudflare-exposed` bridge
network. Any service that needs external access must join
this network.

The tunnel also attaches to the `dokploy-network` so it can
reach services that are only published on that network
(those that don't declare `cloudflare-exposed`). Dokploy
provides `dokploy-network` automatically on deploy.
The tunnel joins `dokploy-network`, which Dokploy provides
automatically on deploy, and sends every public hostname to
Traefik (`http://dokploy-traefik`). Traefik then routes the
request using the domain configured in Dokploy.

## How It Works

1. The `cloudflared` container establishes a tunnel
using your Cloudflare token.
2. The `cloudflare-exposed` Docker network is created
and shared across services.
3. Services attached to this network become reachable
through Cloudflare.
4. Routes and access policies are managed in the
[Cloudflare Zero Trust dashboard][zero-trust].
2. Each public hostname is added to the tunnel in the
[Cloudflare Zero Trust dashboard][zero-trust], pointing
to `http://dokploy-traefik`.
3. Traefik forwards the request to the service that has
that domain in Dokploy (HTTPS off, certificate None:
Cloudflare terminates TLS).
4. Access policies are managed in Cloudflare Zero Trust.

## Environment Variables

| Variable | Description |
|--------------------------|----------------------------------------|
| `CLOUDFLARE_TUNNEL_TOKEN`| Tunnel token from Cloudflare Zero Trust|

## Connecting a Service

Add the `cloudflare-exposed` network to any service
you want to expose:

```yaml
services:
my-service:
image: example/my-service:latest
networks:
- cloudflare-exposed
## Exposing a Service

A service is exposed by configuration, not by Docker
networks:
cloudflare-exposed:
external: true
```

1. Add the domain to the service in Dokploy.
2. Unless it must be public, create its Cloudflare Access
application first, so the hostname is never reachable
without it.
3. Add the hostname to the tunnel, pointing to
`http://dokploy-traefik`.

No network needs to be declared in the service's compose
file.

Traefik's ports 80 and 443 must not be reachable from the
internet. Otherwise a client could send a protected hostname
straight to Traefik and skip Cloudflare Access. On
tuckfow-cloud-01 the Hetzner firewall blocks them. At home
the router forwards no ports to the server.

Preserve standalone access to the Pi-hole widget.

With the documented standalone Compose deployment, Homepage and Pi-hole join separate networks. The documented http://pihole widget URL cannot resolve the Pi-hole container, so the widget cannot show statistics. Provide a shared network for standalone deployments or document another reachable URL and its setup.

Update the standalone Compose network configuration so Homepage can reach the

alternative and its required setup. Preserve the existing deployment behavior
for other services.

Provide a standalone proxy migration path.

If a standalone reverse proxy reaches homepage:3000 only through cloudflare-exposed, redeploying Homepage disconnects it from that network. The dashboard becomes inaccessible. Document how to attach the proxy to Homepage’s new default network before switching traffic.

Pi-hole widget: documented that Pi-hole and Speedtest must keep a Dokploy domain, which is what attaches them to dokploy-network where Homepage resolves http://pihole / http://speedtest. Standalone proxy migration: not applicable; there is no standalone proxy, Traefik is Dokploy's and lives on dokploy-network.

@finallyjay Thanks for the clarification. I withdraw the standalone proxy migration concern for your deployment.

The service READMEs now document the Dokploy domain requirements. However, README.md Line 34 still describes Dokploy as optional, and Line 41 gives standalone Compose instructions. In that setup, Homepage and Pi-hole use separate default networks, so http://pihole cannot resolve without additional networking.

Could you document a shared network or reachable URL for standalone users, or clarify that the widget example requires the Dokploy setup?
