docker rootless  
docker compose  
Ubuntu 20.04 LTS

I used this setting in docker-compose:

```auto
    cap_add:
      - NET_BIND_SERVICE 

```

Or typed this in terminal

```auto
sudo setcap cap_net_bind_service=ep $HOME/bin/rootlesskit

```

the domain DNS records A point to server  
Iptables allow 80 and 443 ports

My caddy proxy server cannot open 80 or 443 ports.

I don’t thinks thats possible. Ports below 1000 required root privileges to open and since the docker daemon isn’t running as root it can’t use those ports.

Due to Docker documentation it is possible, but it doesn’t work.
