 This only talks about integration through Compose,
 but it also applies to docker cli options.

Currently, Anubis doesn't have any Traefik middleware,
so you need to manually route it between Traefik and your target service.
This routing is done per labels in Traefik.

In this example, we will use 4 Containers:

- `traefik` - the Traefik instance
- `anubis` - the Anubis instance
- `target` - our service to protect (`traefik/whoami` in this case)
- `target2` - a second service that isn't supposed to be protected (`traefik/whoami` in this case)

There are 3 steps we need to follow:

1. Create a new exclusive Traefik endpoint for Anubis
2. Pass all unspecified requests to Anubis
3. Let Anubis pass all verified requests back to Traefik on its exclusive endpoint

## Diagram of Flow

This is a small diagram depicting the flow.
Keep in mind that `8080` or `80` can be anything depending on your containers.

traefik-->|:8080 - Passing to Anubis|anubis
anubis-->|:3923 - Passing back to Traefik|traefik
traefik-->|:80 - Passing to the target|target
```

## Create an Exclusive Anubis Endpoint in Traefik

There are 2 ways of registering a new endpoint in Traefik.
Which one to use depends on how you configured your Traefik so far.

**CLI Options:**

```yml
--entrypoints.anubis.address=:3923
```

**traefik.yml:**

```yml
entryPoints:
  anubis:
    address: ":3923"
```

It is important that the specified port isn't actually reachable from the outside,
but only exposed in the Docker network.
Exposing the Anubis port on Traefik directly will allow direct unprotected access to all containers behind it.

## Passing all unspecified Web Requests to Anubis

There are cases where you want Traefik to still route some requests without protection, just like before.
To achieve this, we can register Anubis as the default handler for non-protected requests.

We also don't want users to get SSL Errors during the checking phase,
thus we also need to let Traefik provide SSL Certs for our endpoint.
This example expects an TLS cert resolver called `le`.

We also expect there to be an endpoint called `websecure` for HTTPS in this example.

This is an example of the required labels to configure Traefik on the Anubis container:

```yml
labels:
  - traefik.enable=true # Enabling Traefik
  - traefik.docker.network=traefik # Telling Traefik which network to use
  - traefik.http.routers.anubis.priority=1 # Setting Anubis to the lowest priority, so it only takes the slack
  - traefik.http.routers.anubis.rule=PathRegexp(`.*`) # Wildcard match every path
  - traefik.http.routers.anubis.entrypoints=websecure # Listen on HTTPS
  - traefik.http.services.anubis.loadbalancer.server.port=8080 # Telling Traefik to which port it should route requests
  - traefik.http.routers.anubis.service=anubis # Telling Traefik to use the above specified port
  - traefik.http.routers.anubis.tls.certresolver=le # Telling Traefik to resolve a Cert for Anubis
```

## Passing all Verified Requests Back Correctly to Traefik

To pass verified requests back to Traefik,
we only need to configure Anubis using its environment variables:

```yml
environment:
  - BIND=:8080
  - TARGET=http://traefik:3923
```

## Full Example Config

Now that we know how to pass all requests back and forth, here is the example.
This example contains 2 services: one that is protected and the other one that is not.
