Bridge should be able to route DHCP requests out to pi. Docker rules disallow it.

#cat /etc/NetworkManager/dispatcher.d/99-bridge
#!/bin/sh

INTERFACE=$1
ACTION=$2

if [ "$INTERFACE" = "nm-bridge" ]; then
  if [ "$ACTION" = "up" ]; then
    iptables -A FORWARD -i nm-bridge -j ACCEPT
  fi
fi

  osUbuntu:
    type: os
    attribute: ubuntu

... and /etc/ansible/ansible.cfg contains

[inventory]
enable_plugins = auto

... and ~/.config/lxc/ contains client.crt and client.key generated earlier

Start the containers

SERVER_NAME=:80  docker-compose up -d

Container limits

lxc profile set cricket limits.memory 256MB
lxc profile set cricket limits.memory.swap false
lxc profile device set cricket root size 1GB
lxc profile set cricket limits.cpu.allowance 10%

Git bunch update

for i in `git branch`; do git checkout $i; git checkout set_immune .gitignore; git add .; git commit -m ".gitignore";git push;done
