If you have read my introduction to macvlans and tried the basic macvlan bridge mode network configuration you are aware that a single Docker host network interface can serve as a parent interface to one macvlan or ipvlan network only. One macvlan, one Layer 2 domain and one subnet per physical interface, however, is a rather serious limitation in a…

Docker Networking: macvlan bridge
Docker takes a slightly different approach with its network drivers, confusing new users which are familiar with general terms used by other virtualization products. If you are looking for a way to bridge the container into a physical network, you have come to the right place. You can connect the container into a physical Layer 2 network by using macvlan…
Docker Container Network Types
Docker provides similar network connection options as general virtualization solutions such as VMware products, Hyper-V, KVM, Xen, VirtualBox, etc. However, Docker takes a slightly different approach with its network drivers, confusing new users which are familiar with general terms used by other virtualization products. The following table matches general terms with Docker network drivers you can use to achieve the…

Bridge A bridge is a Layer 2 device that connects two Layer 2 (i.e. Ethernet) segments together. Frames between the two segments are forwarded based on the Layer 2 addresses (i.e. MAC addresses). Although the two words are still often used in different contexts, a bridge is effectively a switch and all the confusion started 20+ years ago for marketing…
