iptables: How Docker Publishes Ports

This technical article explores Docker's port publishing mechanism, focusing on iptables rules for forwarding requests from host ports to containers in separate network namespaces. It provides a hands-on guide with bash commands to set up network namespaces, virtual interfaces, and demonstrate port forwarding, building on concepts from a previous post about IP address creation in Docker and Kubernetes.
