Docker Networking

A network is a group of two or more devices that can communicate with each other either physically or virtually. The Docker network is a virtual network created by Docker to enable communication between Docker containers. If two containers are running on the same host they can communicate with each other without the need for ports to be exposed to the host machine. You may use Docker to manage your Docker hosts in any platform manner, regardless of whether they run Windows, Linux, or a combination of the two....

Network Drivers

There are several default network drivers available in Docker and some can be installed with the help of plugins, Command to see the list of containers in Docker mentioned below....

Common Operations

docker network inspects:  We may examine the configuration information of a specific network, such as the name of the network, the containers that have linked to this network, the type of driver used to construct this network, and other characteristics, by using the “docker network inspect” command. docker network ls: We can see all of the networks that are available on the current host by using “docker network ls”.  docker network creates: Using the command “docker network create” and the name of the driver, such as bridge, overlay, or macvlan, we can establish a new network.  docker network connects: In order to use this command, we must first confirm that the appropriate network has already been formed on the host. Then, using docker “network connect”, we may attach the container to the necessary network....

Conclusion

Only with the aid of the IP address, gateway, routing table, DNS service, and any other networking information can the container learn what network interface is being used. The type of network associated with a container is unknown; it might be any driver, such as “bridge, host, and null.”...
