The netshoot Docker image is very helpful as it includes all the networking tools you might need to test with. I recently used it to mess around with the setup of docker ipvlan networking.

services:
  netshoot:
    image: nicolaka/netshoot
    command: sleep infinity
    tty: true
    stdin_open: true
    container_name: netshoot
    environment:
      - DEBIAN_FRONTEND=noninteractive

Docker ipvlan Networks

Docker ipvlans allow each container to have a unique IP address on a specified network. This removes the need for port mapping, etc. It also allows for some flexibility with firewalls as you can create container specific firewall rules at the network edge instead of mucking around with iptables on the container host.
