ufw allow: permission denied #2

Configuring iptables gives me this error:

ERROR: initcaps
[Errno 2] iptables v1.6.0: can't initialize iptables table `filter': Permission denied (you must be root)
Perhaps iptables or your kernel needs to be upgraded.

In hindsight, it may not be such a good idea to configure ufw within a docker container reference.

If I have to configure ufw within a docker container, I will have to start the container, giving it elevated capabilities (e.g NET_ADMIN).
this will go against the inbuilt security features that isolate a container from its host environment.
