Cloudflared "legacy" tunnels have been deprecated. A switch to named tunnels is needed.

This image mimics the "niceness" of legacy tunnels, but uses named tunnels internally.

All that is needed is a cert.pem, `TUNNEL_HOSTNAME` and `TUNNEL_URL` or `TUNNEL_UNIX_SOCKET`

```yml

services:

  cloudflared:

    image: firecow/cloudflared:${FCF_IMAGE_VERSION}

    environment:

      TUNNEL_HOSTNAME: https://somesub.example.com

      TUNNEL_URL: http://webserver:8080

    volumes:

      - ./example.com.cert.pem:/etc/cloudflared/cert.pem

``` 

These environment variables have other defaults than original.

```shell

TUNNEL_TRANSPORT_LOGLEVEL="error"

TUNNEL_METRICS="0.0.0.0:2000" # See Dockerfile healthcheck

```

Dockerfile CMD is set to `firecow_cloudflared`, overriding this in `docker-compose.yml` or `docker run` will bypass the DNS and named tunnel auto process. 

`TUNNEL_URL: http://webserver:8080` can be replaced with `TUNNEL_UNIX_SOCKET: unix://var/run/origin.sock`
