Unless you specify otherwise with the docker run -network= option, the Docker daemon connects containers to this network by default. In this case, control traffic (traffic related to managing the swarm and the service) is still sent across an overlay network, but the individual swarm service containers send data using the Docker daemon’s host network and ports. The bridge network represents the docker0 network present in all Docker installations. You can also use a host network for a swarm service, by passing -network host to the docker service create command. These three networks are still available to you. and again, when you try to create a Docker macvlan, will fail unless you connect it to the right interface. When you run a container you can use the -network flag to specify which network you want to run a container on. Follow-up question: do you have any networking bonding on your physical NICs This will show up as bond-system, bond0, etc. This will prevent possible network conflicts. If your equipment uses addresses from these networks, you can change the Docker settings. Multiple containers on the same host can talk to each other through the Linux bridge. By default, Docker virtualization system uses 172.17.0.0/12 networks for its operation. The interfaces on the containers talk to the bridge, and the bridge proxies to the external world. The docker network inspect command above shows all the connected containers and their network resources on a. When the Docker service is started, a Linux bridge is created on the host machine. Historically, these three networks (bridge, none, host) are part of Docker’s implementation. The docker0 bridge is the heart of default networking. You can list these networks using the docker network ls command: $ docker network ls
#Docker network interface install
When you install Docker, it creates three networks automatically.

If you have any questions, please leave a comment below. You should also check out the official Docker documentation. Look at Understand Docker container networks and Customize the docker0 bridge docker network prune -a -filter 'until12h' Conclusion We have shown you some of the common commands for removing Docker containers, images, volumes, and networks. We'll guide you through some of the more common docker run commands to help you both test and create your own Docker containers using the command line. By default, the Docker server creates and configures the host system’s docker0 interface as an Ethernet bridge inside the Linux kernel that can pass packets back and forth between other physical or virtual network interfaces so that they behave as a single Ethernet network.
