![]() ![]() The specified gateway is external to the host provided by the network infrastructure.Įach Macvlan Bridge mode Docker network is isolated from one another and there can be only one network attached to a parent interface at a time. 10 representing VLAN 10) or even bonded host adaptors which bundle two Ethernet interfaces into a single logical interface. Examples are a physical interface such as eth0, a sub-interface for 802.1q VLAN tagging like eth0.10 (. Macvlan driver networks are attached to a parent Docker host interface. ![]() Macvlan Bridge mode has a unique MAC address per container used to track MAC to port mappings by the Docker host. Macvlan Linux kernel v3.9–3.19 and 4.0+.To check your current kernel version, use uname -r to display your kernel version.o parent interfaces can also be left out of the docker network create all together and the driver will create a dummy interface that will enable local host connectivity to perform the examples. Any examples using a sub-interface like eth0.10 can be replaced with eth0 or any other valid parent interface on the Docker host. The examples on this page are all single host and setup using Docker 1.12.0+Īll of the examples can be performed on a single host running Docker. ![]() This result is easy access for external facing services as there is no port mappings in these scenarios. Removing the bridge that traditionally resides in between the Docker host NIC and container interface leaves a very simple setup consisting of container interfaces, attached directly to the Docker host interface. Two high level advantages of these approaches are, the positive performance implications of bypassing the Linux bridge and the simplicity of having less moving parts. Macvlan offers a number of unique features and plenty of room for further innovations with the various modes. ![]() The Linux implementations are extremely lightweight because rather than using the traditional Linux bridge for isolation, they are simply associated to a Linux Ethernet interface or sub-interface to enforce separation between networks and connectivity to the physical network. Macvlan is a new twist on the tried and true network virtualization technique. For overlay deployments that abstract away physical constraints see the multi-host overlay driver. The VLAN drivers build on top of that in giving operators complete control of layer 2 VLAN tagging for users interested in underlay network integration. Libnetwork now gives users total control over both IPv4 and IPv6 addressing. The Macvlan driver is in order to make Docker users use cases and vet the implementation to ensure a hardened, production ready driver. ![]()
