Docker for the Absolute Beginner - Hands-On - Docker PID - Demo

The video tutorial demonstrates the concept of namespace process IDs in Linux and Docker. It explains how a Docker container can have its own set of processes with a root process ID of 1, while the same process on the host system has a different ID. The tutorial includes a practical demonstration of running a Docker container with Tomcat, executing commands inside the container, and comparing process IDs inside and outside the container. The use of namespaces to isolate processes in Docker is highlighted, showing how containerization technology allows processes to run with different IDs in different environments.
