Docker Certified Associate Certification Training Course - Macvlan Network

The video tutorial introduces the Macvlan driver, a lightweight network driver that connects container interfaces directly to host interfaces without using Linux bridging or port mapping. It is beneficial for legacy applications and those monitoring network traffic. The tutorial explains how to configure Macvlan networks, including setting up DHCP to avoid IP conflicts. It also covers the two modes of Macvlan traffic: bridge mode and 802.1Q trunk bridge mode, and discusses advanced configurations for extending multiple L2 VLANs to containers, highlighting the flexibility and control over network policies.

What is a key characteristic of the Macvlan driver that makes it lightweight?

• It uses virtual IP addresses.

• It requires extensive port mapping.

• It connects container interfaces directly to host interfaces.

• It uses Linux bridging.

Why is the Macvlan driver particularly useful for legacy applications?

• It uses a unique subnet for each container.

• It requires no IP address configuration.

• It allows containers to appear directly connected to the physical network.

• It provides a virtual network interface.

What must be designated on the Docker host to use the Macvlan network?

• A network gateway

• A physical interface

• A virtual interface

• A software bridge

In which mode does Macvlan traffic go through an 802.1Q sub-interface?

• Direct mode

• Virtual mode

• Trunk bridge mode

• Bridge mode

What flexibility does the Macvlan driver offer in terms of VLAN configuration?

• It allows only one VLAN per host.

• It can extend multiple L2 VLANs through the host interface.

• It restricts VLANs to a single container.

• It requires VLANs to be configured externally.
