Docker does not exist: processes and reliability

Stop believing the magic. We are told that Docker containers are lightweight Virtual Machines, but that is actually a lie. In this Deep Dive, we deconstruct the Docker architecture to prove that "containers" don't exist—they are just a carefully orchestrated stack of isolated processes. I will show you what actually happens when you run docker run. We will inspect the process tree to find dockerd, containerd, and the unsung hero of resilience—the containerd-shim. Finally, we will conduct an experiment: killing the Docker daemon in real-time to see if our Nginx application survives. By the end of this video, you will understand: Why dockerd is just an API server, not the runtime. How containerd and runc actually spawn your processes. The critical role of containerd-shim in keeping your apps alive during updates. How to enable "Zero Downtime" updates using the live-restore configuration.
