Docker Networking: Design, Implementation, and Best Practices

Overview

Explore Docker networking and secure container management in data centers and cloud environments in this 59-minute video. Gain insights into overlay networking and best practices for secure Docker container deployments. Discover the fundamentals of Docker networking, including bridge and overlay networking, MACVLAN, service discovery, and routing mesh. Learn about the HTTP Routing Mesh (HRM) for native application layer load balancing. Understand Docker's network design philosophy, goals, and architecture, including the Container Network Model (CNM). Examine the differences between Linux and Windows networking in Docker environments. Dive into topics such as port mapping, VXLAN, network separation, and sub-interfaces. By the end of this video, you'll have a comprehensive understanding of Docker networking concepts and their practical applications in modern containerized environments.
