AHA! - Finally I found what was missing from a pure Juju install vs a conjure-up install.

lxc profile create netfilter
$ lxc profile set netfilter linux.kernel_modules br_netfilter
$ lxc profile show netfilter
  name: netfilter  
  config:

lxc profile apply juju-91f454-4 default,juju-default,juju-default-kubernetes-worker-590,netfilter

lxc restart juju-91f454-4
lxc restart juju-91f454-5
