Docker Certified Associate Certification Training Course - Binding Containers with Host or Port

The video tutorial explains how Docker containers handle ports by default, which restricts external access. It discusses the need to expose and bind container ports to host ports using the -P option, allowing external access to applications like web servers. Examples of port mapping, including TCP and UDP, are provided, along with practical demonstrations using Docker run commands.

Describe the process of mapping an external port to an internal port in a Docker container.
