DNS & IPv6

# Create an IPv6 network:
docker network create --ipv6 --subnet 2001:0DB8::/112 --gateway 2001:db8::1 ip6net
# And use it in the containers like so:
    ports:
      - "8080:8080"
      - "8443:8443"
    networks:
      - default
      - proxy
    environment:
      - HTTP_PORT=8080
# and at the end of the compose-file:
networks:
  default:
    external:
      name: ip6net
  proxy:
    external:
      name: proxy_default

# Enable IPv6 for docker in general:
sudo nano /etc/docker/daemon.json
# Contents:
{
  "experimental": true,
  "ip6tables": true,
  "dns": ["2001:67c:1434:1:195:149:240:141"]
}
