Docker Networks

The following drivers exist:

• Default Bridge Network
• User defined Networks
  • enable Docker DNS
• The Host Network
  • share IP with Host, like a regular application
  • Run Wireguard directly on the Host with a container as
• MACVLAN (Bridge Mode)
  • receive IP adresses similar to the HOST
  • generated MAC adress
  • like a VM on the same network stack
  • requires subnet, gateway and specifying your host NIC
  • no DHCP
  • requires specifying unused IP for each container
  • issue: sharing multiple mac adresses on one switch port (needs promiscious mode)
    • run on host: sudo ip link set enp0s3 promisc on
  • still uses docker internal DNS
• MACVLAN (802.1q mode)
  • Specify subnets for VLAN
  • Router on a Stick, with Docker Container, on a Host
• IPVLAN (Layer 2)
  • like MACVLAN but use MAC from Host
• IPVLAN (Layer 3)
  • separate isolated Networks, L3 Links
  • networks with the same parent network can talk to each other
  • allows broadcast isolation
• Overlay Network for Docker Swarm
• None
