Docker Networks (EN)

Architecture

Docker Networks are isolated networks that enable communication between containers while enhancing security. They allow containers to communicate with each other without being directly connected to the host network or the internet. Docker Networks can be custom-configured to meet specific requirements for isolation, security, and performance, and are an essential component of container orchestration.
