Welcome to Docker ARP Analysis Documentation!

I’ve been immersing myself in CI/CD pipeline studies lately, and now that I’ve gotten a good grasp of it, I can finally dedicate my full attention to understanding container technologies. To start, I decided to focus on networking, which is the stack I’m most familiar with. In this simple how-to guide, I’ll walk you through observing the Address Resolution Protocol (ARP) in action within a Docker environment. An Address Resolution Protocol(ARP) allows a container to learn the MAC address of another device (in this lab, it’s the bridge and other containers) dynamically. Without an ARP, a ping between containers, external networks, or even a web request between containers and other devices fails.
