Docker networking allows containers to communicate with each other by providing a network infrastructure for containers running on the same host or across different hosts. It enables seamless communication between containers, making it easier to build distributed applications.

Docker provides various network drivers that allow you to define the network behavior for containers. Some of the commonly used network drivers are:

• Bridge Network: The default network driver for Docker containers. It creates a network bridge on the host and assigns an IP address to each container. Containers on the same bridge network can communicate with each other.
• Overlay Network: Used for creating a multi-host network across different Docker hosts. It allows containers running on different hosts to communicate with each other as if they were on the same network.

In summary, Docker networking allows containers to communicate with each other by creating a network infrastructure using different network drivers. The Bridge Network is the default network driver for Docker containers, while the Overlay Network is used for creating a multi-host network across different Docker hosts.
