You can specify the IP address range, subnet, gateway, and other options. $ docker network create -d overlay -attachable my-attachable-overlay

To create an overlay network for use with swarm services, use a command like Afterward, you canД¬reate additional user-defined overlay networks. To do this even if you never plan to use swarm services. Ingress overlay network which is used by swarm services by default.

UDP port 4789 for overlay network trafficД«efore you can create an overlay network, you need to either initialize yourДocker daemon as a swarm manager using docker swarm init or join it to anД®xisting swarm using docker swarm join.

TCP and UDP port 7946 for communication among nodes.

TCP port 2377 for cluster management communications.

You need the following ports open to traffic to and from each Docker host Operations for all overlay networks Create an overlay networkДЇirewall rules for Docker daemons using overlay networks Overlay network, the default behaviors and configuration concerns are different.ДЇor that reason, the rest of this topic is divided into operations that apply toДЄll overlay networks, those that apply to swarm service networks, and those thatДЄpply to overlay networks used by standalone containers. Services orД¬ontainers can only communicate across networks they are each connected to.ДЄlthough you can connect both swarm services and standalone containers to an Or containers can be connected to more than one network at a time.

In the same way that you can create user-defined bridge networks. You can create user-defined overlay networks using docker network create, a bridge network called docker_gwbridge, which connects the individualДocker daemon to the other daemons participating in the swarm.When you create a swarm service and do notД¬onnect it to a user-defined overlay network, it connects to the ingress an overlay network called ingress, which handles the control and data traffic.New networks are created on that Docker host: When you initialize a swarm or join a Docker host to an existing swarm, two Transparently handles routing of each packet to and from the correct DockerДaemon host and the correct destination container. Networks, allowing containers connected to it (including swarm serviceД¬ontainers) to communicate securely when encryption is enabled. This network sits on top of (overlays) the host-specific

#TCP BRIDGE RETRANSMISSION DRIVER#

The overlay network driver creates a distributed network among multipleДocker daemon hosts.
