Each new Docker container is automatically attached to this network.
In case you’re completely new to Docker networking, when Docker is installed, a default bridge network named docker0 is created. Do check it out.ĭocker 17.06 Swarm Mode: Now with built-in MacVLAN & Node-Local Networks support Last year, I wrote a blog post on “How MacVLAN work under Docker Swarm?” for those users who want to assign underlying physical network address to Docker containers which runs various Swarm services. Scenario: Say, you have built Docker applications(legacy in nature like network traffic monitoring, system management etc.) which is expected to be directly connected to the underlying physical network. In this type of situation, you can use the macvlan network driver to assign a MAC address to each container’s virtual network interface, making it appear to be a physical network interface directly connected to the physical network.
