One issue that Docker seeks to resolve is incompatibility. Why Docker networking is importantĭocker allows network administrators to configure multiple networks and add containers to one or more of these networks. For instance, APIs and other resources can be connected to containers through networking. The portability aspect aims at allowing applications to behave the same way in different environments.ĭocker also provides a tremendous amount of functionality and technology through extensibility. The Docker networking design focuses on two major areas portability and extensibility. Network isolation also ensures that everything is executed the right way. This, therefore, serves as an extra layer of security. A huge advantage of the Docker network is that it isolates containers from the internet. The criteria for choosing a network depends on the purpose and function of your container. They include bridge, overlay, and Macvlan network drivers. The model outlines the required steps to provide networking for containers using drivers.ĭocker relies on several drivers for networking. This is achieved through the use of a container network model (CNM). Docker networkingĭocker networking initiates communication between Docker containers and the external world through the host machine.

You can learn more about Docker networking from here. To follow along with this article, you need a comprehensive understanding of Docker. Therefore, having excellent networking skills can help you become more productive. Networking is a critical aspect of container deployment and management.

This article will help you understand how to manage connections between Docker containers. Furthermore, it supports communication to the same or different hosts and the outside world. This process can be achieved through Docker networking.ĭocker has a networking model that allows containers to communicate automatically.

In some cases, containers need to communicate with one another.
